EXTREMELY slow connection speeds

I have an HTC Inspire 4G.
I am using it for the FIRST time, and for the first time in the Philippines.
It was an AT&T locked phone, so I had to root it to unlock it.
I followed the ace hack kit v9 instructions to get it to root. Everything worked relatively as planned except that installing CM7 resulted in a looping boot screen. I fixed that by clearing the cache, but I wasn't too thrilled with the new look. I didn't try my mobile internet yet at that point (I was on WiFi).
I decided to flash the ClearDroid ROM since I just wanted stock with root.
Everything works great. Except my cellular connection is AMAZINGLY unusably slow. I had to manually enter in the APN settings for the wireless carrier here (Globe), and that was a little bit of a pain in itself. I took the phone to one of the local stores here and they confirmed the settings were correct. Regardless, I CAN connect. It just takes sometimes 5 minutes to load CNN's mobile site, for instance. Android Market times out.
I had an iPhone 3GS here on the same service and same locations, so I know what I should be expecting as far as speeds here.
What could be causing this?

Philippine cell phone providers use 900/1800 bands.
Inspire 4G supports 850/1900
iPhone 3gs supports 850/900/1800/1900 so thats why you got better data speeds.
Im sure the phone shows an E for data connection next to the signal bars.

I do get G next to the signal bars mostly, actually.
Calling and texting works fine also ... is the data connection that much more sensitive to frequency?
Also, this HTC's page says the Inspire supports all bands for GSM and GPRS. (I'm a new user so can't post link)

What are your data speeds with the inspire, and what are they with the iphone?
One thing you may need to do is to edit your build.prop
http://forum.xda-developers.com/showthread.php?t=982082

where can i test my data speeds? using test servers outside of the Philippines will probably not be very accurate.
edit: ok i downloaded the SpeedTest.net app for Android. It seems to have several test servers in the Philippines including one 7 miles away. On WiFi I get 1600k down and 450k up (which sounds about right). On 3G I got 999ms ping and -0k down and -0k up. Note that it actually did "run" through the tests, even though it took a really long time. If I disable my connections it won't actually run through the test and will instead give me an error saying it could not connect to the network.
but i should reiterate again that my connection is EXCEPTIONALLY SLOW. when trying to access the Android market, it seems to time out waiting. when trying to use it as a tethered modem, Windows doesn't see a connection to the Internet. loading google.com takes about 10 seconds to load the text, another 30 seconds just to load the google logo. a page like CNN.com took about 5 minutes just to start to appear. data is getting transfered (i guess that is why the connection doesn't time out), but at a very very very slow speed
i no longer have the iPhone, so I can't test, but as far as overall feel, I could get speeds comparable to what I got in the USA in some areas.

G is for GPRS, which has a max top speed around 60kbps down.

which should still be WAAAAAY faster than what i'm seeing. this feels like 1kbps

ok it looks like it was something to do with the ROM.
I did a nandroid backup and installed CM7 again. Internet works fine right off the bat without ANY configuration (didn't even have to define my APNs).
The thing is I personally don't like CM and would rather use something closer to stock. With this new info, what changes when installing CM or ClearDroid that would be killing my internet?

Flash a stock Rom and see what happens. Make sure you do a full wipe. Clear cache and dalvic too.

As it turns out, the CM APN list is over 3 times the size of mine, which would explain why yours would work out of the box. Thank you for the heads up, I'll incorporate their list in the next build, and hopefully it will make everything work for you also!

well, i decided to copy the APN info from CM7. that seems to have fixed my problem...

Hi ZippyDan
I noticed that you wer able to resolve this issue. Im also using an Inspire 4g but cant get 3g. I wonder what u did to resolve it

Sticky or Slow WiFi issue...?

Hi Guys,
My return to HTC from the Rezound days to the U11 have been less than smooth, it seems. First I have the strange SD card corrupt issue... And now I've got this "sticky" WiFi issue...
Let me try to explain:
So, I'm on Stock phone, straight set up as I got it from Amazon. My Internet bandwidth speed tests around 250mbps on an average. And the speeds remain the same when I experience the issue. Essentially what happens is that randomly my internet starts to "stick" meaning, I'd click on a link, it'll take forever and a half and then the page loads out of nowhere. Similarly, I'd be syncing files to Google Drive and my file upload or download starts crawling ?...
The fix: Toggle WiFi on and off and starts flying again! I haven't noticed the issue while on data (I think)...
I have optimizations off for WiFi. WiFi stays fast on other devices... So I'm not sure what's going on? Anyone else experiencing this?
Thanks!

Haven't experienced it for now on 11.
WiFi was something "messy" on my 10, but all good so far on 11.
Might be some router compatibility issues, from top of my head and without first morning coffee see if it happens on both 2.4 and 5 ghz frequencies and if you can disable ipv6 on your router..

Thanks for your response. I believe it's the Comcast XB3 the big black router with the phone lines and 4 computer ethernet ports and etc... In the background, it might be a Cisco router... Have you found a fix for this?

hi. i have the exact same problem as you but only on the 5ghz band. no option to select just 2.4 GHz band is a letdown. i use a virgin media hub 3.0 CH7465, ipv6 in stateless mode. had to disable 5ghz band from router to use the phone on wifi. no issues with mobile data. another issue, unrelated, is the vibration feedback on key press every now and again.

Thanks for reporting and sharing, friend... I'm wondering why more people aren't seeing this or we just got a bad unit? Hopefully HTC finds out and does something about it... ?

Hello !
I am Naphtaline, owning a Sony Xperia XZ Premium and we are experiencing some of your issues there too.
It looks-like the problem could be related to Snapdragon 835 or Android Nougat but we can't be sure yet.
While our problem are not always exactly the same as you, we can say that it could be possible that there are Wifi issues on every snapdragon 835 based device yet on the market.
So, I made a survey to help us understanding this problem. We could then send the results to our brands to help them resolve it.
Please share this link to every people you know owning a flagship device, even if they don't experience the issue. This is very important !
If there are moderators here, if you could make a pinned topic about this survey, this would be marvelous !
https://goo.gl/forms/xePus2lCrjrBjk9b2
Thank you !

this issue is hard to replicate, I tried doing 20 or so speed tests yesterday trying to get it to fail but wouldn't...I know in the past when the issue was present, I switched to 2.4 with no change...I don't have this issue on most routers, only my home router (TP-Link Archer C7) but there again, the issue is so intermittent that it's possible it could happen on other routers but just not noticing.

Pretty sure I've been having this issue since day 1, but I'm trying to tell myself it's just my router, which it's not, as it happens on any wifi network. Also, phone suddenly decided to drop my Verizon signal, and now it won't reconnect. HTC has no fixes for either issue, and Verizon says it's HTC's fault for the signal. Definitely my last HTC phone.

With 5Ghz, if i go to a room little far from where the router is, it would not work but the Speedtest would show amazing speed. Whereas the 2.4Ghz works fine in that room.

FWIW guys the dropped connection effect is happening on my 2.4 SSID as well... Only, momentary fix is toggling off and on.... Have any of you tried a replacement? Maybe we got flawed units?

I am also experiencing this issue and it's driving me nuts! The quick fix is to toggle WiFi on/off, but I shouldn't have to do that.
I have the Xfinity XB3 router, but I do not think it's the router because I also have an S7 Edge where I am not experiencing this issue. I'm going to try using the 2.4 SSID, but from what I've read in this thread so far, it does not sound like that's going to help.

I too am experiencing this issue on the 5Ghz channel of my router. It seems to work initially, but only after a few minutes, it starts to have connection issues. When I switch to the 2.4 Ghz channel, it works just fine, always, no connection issues whatsoever. I just did the survey. Thanks for compiling this, I hope a fix is determined. I have the US Unlocked version, Viper U11 1.3.0 w/ Magisk v12 and module v1.10.1.

The problem is wifi drop-off. Even though the device is showing a good signal the data throughput is weak. If you move closer to the router the wifi will jump back into life. Its due to not having an iso standard for signal strength displays.

You sure about that? I can be 10' from the router and have the issue

Same here..

For me it happens only with my home router networks (Linksys WRT1900ACS).
I found that this drop issue only happens when I'm far from my router when the signal is below -65dBm and only if the 5GHz network is on 80MHz-bandwidth and 2.4GHz is on 40MHz-bandwidth.
Lowering to 40MHz for 5GHz and 20MHz for 2.4GHz solves this problem completely for me.
Two important notes:
1) This behavior only happens with the U11. With other devices like the G6, iPhone 6s and etc. everything works fine at the same time when my wifi networks are on 5GHz 80MHz and 2.4GHz 40MHz.
2) On other 2.4GHz 40MHz-bandwidth networks that I've connected (other than my home's) I don't experience this drops at all with the U11, even when I'm very far away from the router and the signal is very weak.
So this problem seems to be only between the U11 and some routers on some configurations. Very strange

Yall have these Verizon OnePlus 8 issues?

Is anyone else getting freezing using chrome browser? If so what browser do you recommend? I've tried Firefox to and Opera for some reason this phone hates. I don't get why this phone is so slow. Mine takes a minute to process anything. Really hope they fix these software hickups. I guess FR but that would be a big job. The battery consumption seems to be the only best feature on this phone.

Yes, seems like it's a OnePlus problem. No one has a solution that I've seen yet.
I just minimize Chrome and reopen it and it works again.

It's not just on this phone. I just came from the Essential phone and Chrome's been doing that for months. It's Chrome, not the phone. I don't think the built in webview is playing nice with the os. Maybe try Chrome beta?
Question: are you using a custom DNS or VPN?

It's also happening to me, I don't use any VPNs nor DNS. I think this is a OnePlus Problem, maybe they'll address it in the next update. Let's report this problem guys
Edit : I'm not on a Verizon version, mine is IN2010

Funny thing is whenever chrome freezes, going to the home screen and returning back to the app fixes the issue ??*

It's not OnePlus, it's Chrome. Acts the same way on the Essential PH-1. Try Safari or Microsoft Edge browser, or any one that uses Android web view.

Nice. Glad I came across this noticed it instantly when I first got this phone back in April course I couldn't find anything about it then. And oddly it seems like it is way worse and 90htz. Was about to return too vzw. Honestly was thinking it may be a device issue Till I read posts Any suggestions? Gonna try brave

Not really sure where to ask this question but Verizon OnePlus 8 UW. No root or anything outta the norm. Constantly having intermittent data loss, intermittent hotspot loss, calls and texts as well I'm sure since they pushed an update couple weeks back. Message I get from there network troubleshooter says( Your phone can't auto switch too a faster network if it's available. Your better off too use Cdma/Lte or global mode for better signal strength). Far as I know Cdma had been reserved for EMT/Fire etc. Problem seems too arise only when the silly 5g icon comes up. So thinking when it tries too switch too 5g its having that intermittent loss going back to global mode an getting hung up somehow as a simple restart fixes it temporarily. If I was rooted I believe a prl or apn change would fix it maybe. So tired of dealing with Verizon techs, Any help it fix would be great

Sorry ta hear I've done a lot of searching and can't seem to resolve it. Dealing with Verizon it's just getting so old I believe I'm going to just try an root, flash, etc. That or go T-Mobile. If I may ask are you in the States? I'm in Florida btw. Very populated city Clearwater is a big fact and it's a problem all around

I've had Verizon family plan for 20 years now. So I have to deal with it. I remember buying old Galaxy s3 and moding the hell out of it. But I'm older and don't have time like I did when I was younger so I'm stuck. The problems on my OP8 5G UW just accelerated. I'm pretty sure it's software related. Last system update was a "network improvements" haha- yeah right! Since after I've been in hours and hours in Verizon chats, calls, I've spoke to OnePlus techs, I've done replacements, sim swaps, clean resets. Nothing is working to resolve my 1mbps download speed network is slow as hell, 17 Meg's 20 min. Tomorrow I'm talking Verizon tech to get my 4th replacement turned in and hopefully get a Galaxy S10 FE. I always wanted ONEPLUS but not this way. I'm done

I'm in Frederic Michigan, near Grayling. Rural area, but Verizon is king up here. And, with a low population density, I've had really great service for years. Up until recently. Wife has a Galaxy Note 9 and doesn't have half the issues.

So update. I wasn't allowed to move on to another phone with old big red. I exhausted my replacements with Verizon my only option now is to pay this off and move on. I did get some slight improvements turning the automatic to manual in Network Mode. It seems like I don't have the constant 5g/4g fight. As for original topic, I use the Samsung browser and I don't have any hanging or freezing.

Yea I'm kinda and the same boat got a phone didn't work good paid it off early got the OnePlus and now this I did switch to manual too and it helped a little bit. But not a lot we can do I definitely won't be buying any more Vzw phones. I can't even maintain consistent hotspot for over 30 40 minutes ever since past update. I have the 5G icon now that's not really 5G speed at all. I've gotten true 5G on this phone a couple times and it's amazingly fast. The 5G icon fades an drops too 4g when it does it kicks me off discos hotspot an network sometimes. I just don't have the will to deal with tier 3 tech anymore lol. I had prepaid for seven years with Verizon and it worked flawless many different phones over the years soon as I got postpaid went to hell

I'm in New Orleans and delt with all Network connection problems too. I'm on my 3 rd replacement and spent hours, days, and weeks ping-ponging through Verizon finest bull**** techs, Verizon sent me to OnePlus tech where the tech there referred me CDMA LESS and after a long work about found out that I was already on CDMA LESS. The only thing that helped other than bazilion factory resets and it's not the solution by any means is turn the automatic best Network set it to manual Verizon 4g. You still get the stupid 5g emblem but I've noticed an improvement as in connectivity. Not stable, I get interference and dropped calls all the time. Also i read something on how Verizon used cheaper antennas for their fake 5g push. Also could this be a conflict with Oxygen? I'm reading a lot of similar Network issues after updates.

Right on thanks, Not sure if manual mode actually sticks. Does it just switch back? But yes I too figured it'd help out. When I do let's say Run a diagnostic from Verizon's app one of the first things it says is this phone cannot auto connect to use lte/cdma for better signal. And that's wild it's connected and automatic mode. So it's obvious it's a hardware issue or software issue on their end. If they would allow you to control the phone we could fix it. Just got my first replacement today. Fixing the boot it up soon and see what the deal is software wise etc etc. The connectivity issue were both having is just 1 issue lol. I've got six or eight more easy. Mine seems like it's good data connection wise either with the fake 5g icon or without it. Bars will start fluctuating pretty rapidly (It's searching) I'll lose the 5G icon in turn lose hotspot lose date connection etc. Then it will come back with no 5G icon, connect, Be gr8 for about 10min or I reset prl & net setting. Someone tell me there 5g for most parts like here & there is basically just a glorified 4G LTE. There 5g coverage map clearly says or did there's no 5g here. I believe this to be true as I have connected to real vzw 5g in Tampa an you can tell big time!! This 5g even with there signal booster they sent me is not any if all better than 4g. Could kinda care less about the 5g it's the consistent intermittent network issues. Pls lmk what you find out either by p.m. or what have ya. I'll do the same. I'm gonna try this new vzw root I believe an switch too global or whatever I need too do weather it voids certain things or not lol. Sorry 4 the long read but wanted give ya what I knew. Here's a shot of there diagnostic mess. From vzw. An a shot of real 5g speed test before the updated deal that displays the 5g icon

Question GSM issues, sudden disconnection?

Hey guys,
So I've received my P7P a couple days ago. Ordered in Romania from the official Amazon Store. 5G, VoLTE, and VoWiFi don't work, as you all know.
But the biggest problem I have is that the network just completely disconnects if I leave the phone on the desk for a couple minutes. I have people messaging me and asking why they can't call me. When I look at the phone, there's no GSM signal of any kind. This is in a location where I have full 5G coverage otherwise.
I had to go into airplane mode 2 times before I was able to receive a call. The first time it connected to LTE for a couple seconds and then it completely dropped again.
Not to mention it takes forever to connect again after going in an area with weak signal.
I've updated to the Beta and the issue persists.
Great software, great camera, whatever, all useless when you can't fulfill your main purpose of being A PHONE.
Anyone else with issues like this? This is all I've found: https://piunikaweb.com/2022/10/20/pixel-7-7-pro-no-network-or-no-service-connectivity-issue/

Does the phone have the LTE bands it needs to even work where you live? If not, then I doubt there will be anything you can do but return it and look to another OEM.

oh LTE works well. 5G doesn't work.
It just gets disconnected from any kind of cellular network and gets no signal after a while.

Have you taken the day one OTA? That fixed the problem for most of us. I haven't seen any X or ! since the first day. Before that update I was having my connection drop every 10 minutes or so.
If you already have taken this update, you may have a defective model.

Try force stopping Carrier Services and Google Play Services and deleting the storage for both. That help me tremendously with connectivity issues with Pixel 6 Pro.
Might want to try Carrier Services beta as well.
Another thing to check is your APN settings. Make sure they're what your service provider recommends

I immediately updated before unlocking the bootloader and rooting, I don't have network outage or anything. 5G seems to be working as well, at least available in settings, I'm yet to test it in 5G area but where I live, there's no 5G actually so it would not bother me much anyways. I'm so far very happy with it

Question Mobile Data extremely slow on Samsung Galaxy S22 Ultra (Snapdragon)

I have a Samsung Galaxy S22 Ultra with Snapdragon processor.
I use dual SIMs from different network providers, and both support 5G.
When I'm on mobile data, I find that the internet connection becomes extremely slow, and sometimes doesn't work at all. Switching to the other data SIM under SIM Manager Settings sometimes helps, but often the speed is pathetic. Even though the status bar shows 5G or LTE+ or LTE, the speeds I get most of the time on either SIM is like 2G.
I'm not sure if this has anything to do with the problem, but please note:
1. I use Netguard to block most system apps from connecting to the internet.
2. I use private DNS (dns.adguard.com) and I often get this notification Network has no internet access (Private DNS server cannot be accessed) which goes away after a few seconds.
Is there anything that can be done to resolve this?
Thanks.

Not yet.

adguard is what is causing that, I couldn't find a workaround so have to stop using it, for what I saw, looks like any dns causes the same issue

I have tried turning OFF the dns, but that didn't help.

I have bad news for you, I bought one yesterday and it made calls without problems, but the internet is terrible, and it turned out that the cell phone is on a blacklist in Canada by a cell phone company there and hence the problem.

I'm not in Canada and the S22U isn't on the blacklist of any telecom company here.
At best, this is a software issue.
At worst, this is an issue with the network modem/ radio on the device.
And I hope it is a software issue.

disable 5G and use NEXTDNS ultrafast servers
my LTE is 30-160 MBPS
my 5G is 60-280 MBPS
5G is draining battery like a crazy--so its off for me

I hope all basic troubleshooting is done on this matter. Even if this is not the issue with the operator then for sure it is a Software issue, because, in my S22 Ultra, everything is running perfectly;y fine.

Me, 908B Europa.
When i reiceive a small video on whatsapp it takes a minuteto open or fail..
Youtube, is like is charging with a shovel... Like a 50 euro phone..
I use Private DNS dns.adguard.com. I disable it and is ok now.
Thank you for the tip.

Try this: Improve your 4G.

Have bookmarked it. I use dns.adguard.com. I'll give it a shot sometime.

It is most likely a software issue only.

Turning OFF private DNS helps, but only rarely. When i have the problem, nothing i do solves it, including reboot. And when it works, it's pretty much on its own.

Interesting. I see that I can uninstall it (as opposed to disabling). For now, I have deleted it's app data, restricted battery usage and blocked it from accessing internet using Netguard. I'll see how it goes from here. Thanks for this tip.

I was using dns.adguard.com. I disable it and it works. At least much better than witn dns private dns.
Dns.adguard.com work super fine on my Oneplus phones since 2015.. till s22u.
Also i uninstall Google's Carrier Services, like our friend say. Don't see much difference for my phone..
