[Q] 3G in one direction but only 2G in reverse. - General Questions and Answers

So I take the train every day to work and I've noticed that in the morning I usually have a solid 3G signal the whole way but on the way back I barely get 2G and browsing is practically impossible a lot if the time.
I know that signals can somewhat rubber band and be slow to hand over. However half way through my trip I stop at a station and the train sits there for about 5 min yet my phone (Nexus5) will still not attach to 3 or 4G (rebooting does not help). In the mornings going the other way I don't have this problem and always get at least a good 3G signal. What gives?

Ask your carrier. They most likely drop speeds to allow more users to use their data but that's only a guess. Only your cell provider will be able to answer this.

[Q] Radio Problems anyone else?

I live in Manhattan, so my day consists of going underground for subway, and then back out at least 4 times per day. I have noticed several times that my radio never RE-grabs a signal when coming above ground it just sits with the bars and an X signifying no signal, in broad daylight...until i reboot the phone and it then promptly grabs signal. I have a buddy with a NS and he noticed this too...we also noticed it happens mostly when we are listening to something when emerging back above ground. Not sure if that has anything to do with it, or if it isjust cooincidence...however, has anyone else noticed their NS radio not grabbing a signal when back in range??? It is SO annoying to be walking around for 10-15min after coming above ground, to notice you have been cut off the whole time.
just instal the airplane mode on/off toggle
and hit it when you are back out on the surface
some times it's slow for the machine to grab signal
yes, i have noticed
like when i go into the basement, or server room, or other places with NO signal
and go back out to a place that I Know there is signal, yet it still in X mode
so, i just swap on/off airplane mode, and it works right away

I'm also a metro north commuter and the same thing happens to me randomly as well. I can go days without it occurring once, however sometimes it'll happen twice in the same day. Attempting to cycle Airplane Mode just locks up the device as well, so rebooting is the only option to restore network connectivity.
Noticed this as well when I'm in and out of subway stations. It hasn't been happening recently but sometimes playing around with the settings in the *#*#4636*#*# menu might help, like selecting GSM PRL or WCDMA preferred.
Anyway, I had the same problem with my Vibrant... never had the problem with my Nexus One or MyTouch 4G. Maybe HTC's hook onto networks better?

I normally loose signal completely when I am in the underground parking lot of my condo building. But as soon as I am outside it connects almost immediately.

I've got the exact same problem, not sure how to resolve it. Really wish they would push out an update and fix these annoying issues.
I've set my phone to WCDMA Only ( since and on boot up it doesnt connect to a network ) & WCDMA Perferred doesn't seem to want to stick.

i have the same problem
Same problem with my Nexus S. Toggling airplane mode don't help. I have to power off/on my Nexus S then I get the signal again.

Bad reception, disconnects and 4G to 2G....

I hope its my network and not the phone because I love it! At my home in my house I get frequent disconnects and the 4G keeps shifting to 2G. Outside in my driveway it gives me 1-2 bars and none sometimes until I drive out about 10 blocks then it gets better If I'm out and around with in 1-2 miles it get better but still it keeps dropping to 2G intermittantly. I get 3 miles out and I get 2500 down and 500 up when the 4G stays on and 3 bars. Now before I got this phone I had MetroPCS and I had a bad connection from my home always, then my Virgin Mobile phone was better. Now with T-Mobile I would think it woud be better but no...it's worse. T-Mobile says they are going to send a technician with in 3-4 days to check out the problem if there is one. I guess if within 1 week nothing gets better and T-Mobile has nothing more to say I'm returning the phone. I called LG but they cant help, there powerless due to the tornados. The representative said, that based on my explanation it seems to be a network problem. Any ideas? Anyone else having problems? I see some other threads with some issues but not too much detail. I'll update when something happens

Constant network issues

I am on my 3rd device in 3 days. First one was rooted, second one was not. This current one is also not rooted as well.
Unless I am very unlucky, I am going to assume there is a definite issue with the network configuration on this device. Status says I have 3 bars of 4G coverage, however I cannot connect to the internet at all.
Network Signal Info says I am on UMTS with a -93DBM, data is connected. However nothing will load. If I put the phone into airplane mode and then turn airplane mode off the networking comes back online. Speeds are slow though, barely able to perform basic mobile web browsing and watching youtube and such isnt possible. Too slow an too long to buffer.
This doesn't only happen at my house, it happens in other areas as well but it does happen constantly at home. I a not a heavy data user on my account, 1-2GB monthly, so Tmo says they arent throttling me. They have replaced the SIM every time with the devices as well.
Suggestions? If I cannot figure this out soon I am going to cancel my service as I cannot pay for a service and phone that just doesnt work. Tmo seems stumped. They just keep replacing phones since I am within my 14 day return/exchange period.
However, 3 devices all having the same issues sure seems to either prove the phone has an issue, or m general area of Tmo service.
I live in downtown Tempe, AZ.
Your wifi works?
I have the same issue in my house... I have a weak signal and 4g drops down to 2g which is terrible.... 4g downloads are 3Mbps, but uploads are under 100kps
I changed the network mode to wcdma only which helps significantly. 4g drops, but quickly returns...
Give it a try...
I'm having the same issue here in Orlando. I've had 2 phones now (first one was just a bad unit) and both have had horrible network connectivity and reception. I take my SIM card out and put it in my 2 year old MT3G and it gets perfect reception and fast data transfers while the G2x is choking on network transfers.
Go complain here in LG forum. This is software issue.
http://www.lgforum.com/forum/boards/general/lg/topics/g2x-wifi-problems
have full bars but cant download anything. just sits at waiting for data connection.
We really need a baseband modem that works better. My bars goes to zero then to edge and then to 3g constantly. Any time it switches between the connections then the the bars goes to zero and it says there is no conection. Also noticed that 3g connection fluctuates very bad while doing a speed test.

How are you getting 3g? Unless you meant to say 4g?

T-mobile only has 3g connection avaliable where I live, of course it says 4g on the phone but in reality it is only 3g.

I wonder if there is an issue with our network in Arizona?? I live in Chandler, and work in Scottsdale. my data times out ALLL THE TIME. Both here at home, and at work. Same with my text messaging. Literally, I do exactly what you do with the "airplane" mode. That's the only way to get my data and text working again (besides restarting).
Here are the issues I posted in the LG Forum:
http://www.lgforum.com/forum/boards/carriers/t-mobile/topics/few-issues-with-g2x#26861
(first issue posted is what you are talking about)
I dont think this is a regional issue. Downtown Minneapolis here, and I cant get it to stay on wifi or Edge/4g for more than a few minutes at a time. G1 has no trouble and shows strong 3g while my sisters mt4g shows full 4g. 4g/E symbol just flickers on my g2x leaving me with no connection. I can connect to wifi fine, but even with wifi sleep set to never it still disconnects every few minutes, and has to be toggled on/off to reconnect. Until toggling it just sits flickering 4g/E with no data connection.
I've never seen my Evo drop a E/4g/wifi connection and struggle to reconnect once in the year I've had it. My g2x does it almost every time I pick it up.
Did you try going into Mobile Networks in Settings and changing the mode to WCDA Preferred or something? That'll stop the flip flopping. That's what I have it on and that's what the phone came with out of the box.Also try Auto in that menu.

Data dropping

My phone has dropped data randomly two times this morning. I could only get it back by doing a switch to airplane mode. Anyone else with this problem? Is this a phone issue that I need to get a new one?
Sent from my HTC One X
Mine has dropped several times. when coming to and from work. It seems to always happen when it connects to wifi. when i leave work and its wifi, i lose all signal entirely.
I don't use wifi though that's the thing. I called ATT and they said it may need a new simcard......which this was. So I swung by and got one and the lady at the store said that my phone may be going bad! LOL wow I love how they train their people.
YES. Most definitely, this is the same problem I'm experiencing. I had another thread posted about how the 4G icon was lit but there was no signal. The icon now seems to be a little more accurate...But still.
At home I switch on WiFi so I don't run up my data but if I look at the settings for mobile network the status underneath in gray text keeps showing that it connects and disconnects. Endlessly. The phone isn't moving. My wife has signal on her iPad and iPhone (I know those are 3G).
I have to turn on airplane mode and then off...Then mobile network on and it seems to help a little. However it's still super spotty.
This is pretty much only indoors but I don't know. I'm going to go around town and try it out. On their coverage map I'm in a big zone of LTE coverage. Outside I have seen 30Mbps on LTE using speedtest.net app. So I don't know. I thought it was very odd given the houses here in CA don't exactly have super thick insulation and every other cell phone (Sprint, my wife's on AT&T, etc.) seem to be AOK. It's just this new One X that just can't stay connected to the 4G.
Going under settings > about > network ...
I see my signal strength....some readings are...
-109 dBm 4 asu
-101 dBm 6 asu
-107 dBm 2 asu
I have no idea what values I should be seeing - what is considered good?
Mobile network type says HSPA. Service state says in service. Icon up top is 4G with one bar. If I turn off WiFi I could not load a web page or anything. That's what annoys me. I usually see like 2 bars and that's fine...But if I see the damn bars and the 4G icon....I sure as hell expect the data to work, even if a little slower.
It's just SUPER flaky. Again outside seems to help but to be honest I haven't sat and watched it. For all I know it could be connecting and disconnecting over and over outside as well but just have a stronger connection when it is actually "on."
I'm annoyed and speechless. I'm not in the boonies. I've never experienced anything like this before. I'm actually at my desk in front of a window. Uh...WTF?
Just picked up lunch and watched the data while on the trip.
This phone is unusable. It's gotta go back. Well, I guess it's welcome back Sprint. Sooooo disappointed.
All I got was HSPA. The only time I get LTE and those fast 30Mbps down is at night time. AT&T is such a joke and their network is NOT ready for this phone.
I'm in Palo Alto, CA. It's not the middle of no where. This is embarrassing. Either that or somehow I have a defective phone or SIM card or something I have no clue here...It's really really bad and I'm obviously not the only one.
3 days and it's been horrible, the only reason why I didn't notice sooner is because I've been using the phone on WiFi most the time.

how fast is the HSPA you're getting?
1-3.56Mbps down and 0.04-1.03Mbps up.
Out on the street downtown.
Best I've ever had was at night on LTE 30Mbps down and like 17Mbps up.
All to the same test server. Trying servers several states away it varied, sometimes I'd even see 20Mbps down to a far away server.
Again this is all WHEN I'm actually connected to the data network.
The thing just can't hold a connection. Constantly dropped.
edit-- ok so right now same time of day, servers, etc. Sprint's 3G is a little slower, but at least I'm not getting dropped.
and on a side note, i got a REALLY helpful lvl1 tech support lady on the phone. much better experience than i thought. there was an issue in the area before. but basically i'm going to give it another shot. if no good tomorrow, swap for a new phone. they'll call me back friday and we'll see... crossing my fingers.
Any update on this? I've got a new One X and work night shifts twice a week. I've notived tonight that the data drops when the phone is idle and obviously nothing pushes.
There's got to be a way of turning this off. I can see why HTC would call it a feature, but there has to be a flag or a switch somewhere....

3G cell reception issue and fix

I just want to write this post maybe it will help anyone that has or will have the same problem. I looked all over the internet and could not find a fix, so here is my fix. Hope it works.
I work over seas on oil rig sites (remote locations) so I talk to my wife and family back home via different VOIP apps so its important to get a 3G signal, usually I lock WCDMA only network and get at least 1 bar which is sufficient. All of a sudden I started experiencing very weak 3G signal on my phone, weirdly this was at the same location where it had full bars in the past. This only applies for 3G, I could get 2G signal no problem.
In other areas that I know had good 3G signals and towers were close, it would work alright outdoors but once I get behind a door or a window 3G disappears even if I have it locked. I put in my sim card in my old Galaxy Nexus and it had 3G indoors with no problems at the same place and right next to the N5. So I started testing with both phones right next to each other when I lock 3G with the same SIM the Galaxy nexus would get 3 bars while the Nexus 5 would get the empty triangle (emergency calls only).
I couldn't get out of my mind that I dropped my Nexus 5 a hard drop, but I have a rubber case that took all the shock and the phone didn't get a scratch on it. This was before the 3G signal starts getting funny. Couldn't help but feel that I broke it somehow though. I felt like this might have got something loose inside. What didn't make sense to me is that if the antenna didn't work it wouldn't get 3G at all, indoors and outdoors.
So Step 1, I assumed it was a software issue. I went through a painful hard reset. To my surprise it still had the same issue afterwards.
Then out of desperation I saw this dude's video on how he couldn't lock GPS until he opened the back of the phone and found that the GPS antenna was not connecting straight.
youtube com/watch?v=K1-uCIb-t8I[/url]
So I started searching for where the 3G or 2G antennas are on the N5, but couldnt find anything that points that out. The phone was worthless to me like that so... I took a deep breath and decided to open the phone. Keep in mind, i'm an oilfield engineer and I still had a feeling i might [email protected]#k the phone up, specially that I did not have any tools with me.
So I watched this video on how to open up the back cover:
youtube com/watch?v=mkbmtu-1KSQ[/url]
and went through this guide on what's inside the N5:
theregister co uk/2013/11/05/nexus_5_teardown_shows_a_light_touch_thats_easy_to_fix/[/url]
Then I opened it, couldn't find anything to do, except maybe clean the minor dust off and blow on the ICs a bit. There is alot of pins that connect to antennas located on the back cover itself, so I closed it up, made sure its closed tight and all the pins touching, put in my SIM, and GOD DAMN!! IT WORKS AGAIN... I was getting full bars 3G!!!
So what I figured is that when I dropped it, one of those pins moved a little bit away and broke the connection between the antenna and the IC. Works great for the last 5 hours, solid connection.
Hope I would help anyone with this

Thats nice , but lots of ppls have the signal issues with nexus 5 , and it isn't antena disconect for 90 % if us. I have separated the phone many times. , done about 5 hard resets's tried diffrent verions of radio's diffrent ROM's etc... nothing work's. Frineds have nexus 5 2 of them , and they can get 3g and 4g when they want, and i can only get Edge which is 2g. which is unusable..... I noticed that i have 3g only when i am in other towns, but not mine home town.... I tried diffrent sim cards, and diffrent netowrks, nothing seams to get the 3g at home, plus the gsm sucks, it interupts the calls.. So i must be the frequencies of the working 3g network in mine home town ? Then how i don't get 4g ? Why other ppl with the same phone, and same network have 3g when put next to mine ? NO one knows...
Same Issue
i am having the same issue, just having "E" Edge and cannot connect to 3G/4G, done everything to resolve the issue, took apart the antenna part of my phone but all the connectors and wires are intact, did hard reset several times, tried different ROMS including stock ROMS, tried the *#*#4636#*#* selected all the Radios but no luck, used 2 different sim cards but no use, same damn "E" in the status bar, APNs are all in place, nothing is wrong with the settings so far, dont know wots da problem with this set.
Please help us.
