Tether connectivity issues - General Questions and Answers

I'll lay out the devices and then we'll go from there.
Droid 4- stock rom, rooted, running wifi tethering.
Tab 2- stock rom, rooted
Droid 2 global- CM9, CM7, and Miui rom's, rooted
Compaq laptop- vista 32 bit
Mifi 4g- no mods, just updated software
S3- stock rom, no root
iPhone 5- stock OS, no jailbreak
Ps3- just updates, no hacks
The d4 is obviously my hotspot as well as the mifi. All devices connect to the mifi without issue. All devices except the d2g connect to the d4 without issue. Occasionally the d2g will connect to the d4 without issue and run just like the tab2. I've bounced between roms on the d2g and even set it back to stock with the same results.
So the question is this- what needs to be done to improve the reliability of the wifi connection between the d2g and the d4? When connected to the mifi, the d2g acts like a brand new phone. On the d4's hotspot it's laggy and drops the connection.....other times it'll work well albeit not as well (speed and performance) as the mifi.
Suggestions? Despite the low post count tinkering with the root/ rom/ etc is not new to me. Thanks in advance.

No suggestions folks?

[Q] Droid1 MIUI Tethering Problems

I cannot get wifi tethering to work on my Droid 1 when running MIUI, stock froyo, or Cyanogen. I have tried Wireless Tether on all three ROMS, I can connect to the phone, but no Internet data is transferred. I'm currently using MIUI 12.3 and found that it has a built in wifi tether that also fails. Barnacle didn't work either.
From what I can figure out this may be either a kernel issue (I never changed it from stock, but MIUI may have its own?) or a problem with how I achieved root (superoneclick). I appreciate any and all advice! Thanks!
I am curious to see what the answer is. sorry i am no help to you. but i also have a old droid that i want to mess with first before i start messing with my evo.

[Q] TMob G2 w/Google + ROMs = shattered dreams

Ok, so I just got this phone on the 2nd and have been extensively looking around for stable ROMs. I've found two ROMs I particularly love, SuperVillain and SparkMods HotSauce, I also rather enjoyed GingerVillain. But all of these seem to have some serious drawbacks with the G2, or maybe just the T-Mobile network, I have no idea. But with SuperVillain, my bluetooth won't work correctly. GingerVillain breaks my WiFi (won't stay toggled on longer than five seconds), and I've yet to accomplish getting the android market app onto HotSauce. And across the board of all the nonstock ROMs, picture messaging absolutely will not work.
So my question is, is there a stable ROM with full support for this phone or do I have to be stuck running this beautiful device at 800mhz?

Xoom ICS & Cisco Access Points

This thread is only for people running a Cisco Access point, preferably a Aironet 1200.
I currently have the 3g/4g version, and this behavior seems exist on all ICS builds I've tried.
I started a thread on Motorola's forums here.
I have 35/35 at home, and on pre-ics builds I get about 25/25 on my xoom. With ICS builds however my download is about 400kb-1200mbits. With upload being 25mbits. So it seems to only be on the downlink where the issues exist.
I've tried building it from source, I've tried other roms, everything that is ICS is slow download which makes streaming terrible.
My Nexus S running ICS does not have this issue so it seems something specific to ICS and the XOOM.
Anyone running the same sort of equipment as me, and running into the same problem?
Thanks
I got a Xoom on stock ics, and I have a bunch of aironet 1231g and 1242ag aps at work. I could try some stuff out if I knew what you meant by the 35/35 or 25/25 stuff, I probably wouldn't want to change my xoom that much with roms or anything (I just rebuilt it tonight to see if it fixed some slowness I was seeing after the ota to ics) but could test on stock ics, just tell me how your testing it... if it makes a difference the aps are all light weight aps managed by WLCs. I could probably snag a 1242 ( and maybe a 1231 if I can find a spare one) and dumb it down with autonomous image if that is more how you are rolling, but it might take me a couple of days...

I'm running
Cisco IOS Software, C1250 Software (C1250-K9W7-M), Version 12.4(25d)JA, RELEASE SOFTWARE (fc1)
What I mean by 35/35 is thats what my internet is at home. But any speed test will show the issue if it is a cisco issue. You'll see that download is terrible, and upload is normal.
Im still not sure what 35/35 means, i've never seen any metrics for throughput / network performance displayed this way...

35mbits over 35mbits.
I have a symetrical fiber connection that gives me somewhere between 35-45mbit download, and 35-40mbit upload.
We found a solution on the other thread. It appears that the new broadcom drivers are now 802.11 certified and there appears the be a bug that causes 802.11 draft APs achieve data decent data rates.
So here are the 3 fixes.
1. Buy a new AP
2. Disable you're mcs rates and lose 802.11n
3. Pray that motorola fixes it.
I'm currently running with 2. Shopping around with 1. Oh and have no doubt in my mind that 3 is a pipe dream.

[Q] Hotspot... Stock Rom vs Custom Rom

I have no problems using my hotspot with any custom rom i put on my phone. But any stock rom even the modded stock roms stop working after my allotted 5 gb. I have tried the hotspot fixes, changing the tether dun value to 0 and i am still blocked. I am on the 80$ unlimited t-mobile plan on the d850. I have no problems with pdanet tethered with stock. I can even make the laptop a hotspot tethered. Whats the difference and can i implement that mod alone in a stock rom?
I am a newb I admit. No script or code in my my language although I would love to speak Klingon. But it looks pretty clear that I have stumped the pros. Lol No I'm sincerely being a whole lot of not serious. But if I'm in the wrong forum... Maybe I should be in trouble shooting? Anyway I know I'm not the only person frustrated by wanting to use LG stock apps and not being able to use the Hotspot unlimited as done with a custom rom. No worries. I will chase the solution down.

Galaxy S 4G- How Can I Upgrade From 2.3.6?

Upgrading firmware question
I have a samsung GalaxyS4G from T-Mobile,
Model # SGH-T959V
Firmware 2..3.6
Baseband Ver. T959VUVKJ6
Kernal 2.6.35.7-T959VUVKJ6-CL694130
Build# Gingerbread.VUVKJ6
3 days ago I was finally able to upgrade to this 2.3.6, prior to that I had only 2.2.1.
I was able to upgrade with Kies Mini thanks to Samsung support.
I contacted Samsung Support Friday asking if I could now upgrade again, I was given the standard answer that I always got when asking about upgrading from 2.2.1, "There is no upgrade for that phone" Just lucky I finally reached a agent at Samsung that had the knowledge or at least the willingness to help or I would still be stuck with Froyo 2.2.1.
I have rooted the phone with Kingo Root and it now shows the phone is rooted.
I am not looking for the sky but would like to at least up grade to Jellybean if not more.
System Storage Used 296 MB, 219 MB free. SD CARD has 130MB used ,839 MB free
Any suggestions?
I realize this phone is OLD and most people have moved on but I have only this phone given to me by my
Son I could not afford a new phone these days.
I am just trying to make this phone as close to today's newer phones as possible.
I was also told that with FROYO 2.2.1 I would get no better then 2G wifi, and that I needed to upgrade the phone to get better wifi service, I thought Gingerbread 2.3.6 was the answer but I only get on occasion 3G and have yet to get 4G LTE although I have a tower less then 2 miles from my house.
If anyone has some suggestions as to what is the best firmware this phone can handle it would be appreciated if you reply.
Hey man.
The only recent official firmware for this phone is 2.3.6. If you want to have Jelly Bean, then you will have to get a custom recovery and flash a custom Jelly Bean ROM.

YES I understand that is the official update, I am trying to get some input as to what version of Jellybean or ? would be good for this phone without killing speed.
Any suggestions Please
My biggest reason for upgrading is I only have 2G service with FROYO and most always with Gingerbread as well, I was told by T-Mobile I would not get any better then 2G with FROYO but I should get 4G LTE with Gingerbread 2.3.6 but I have not gotten even close to that and still drop signal a lot.
Well then you can search up the Jelly Bean ROMS that are floating around. I don't know which one is the best, since I haven't flashed those yet.
I have been searching for a rom but seems that this phone has very little support, yes it is 4 years old and only sole thru T-Mobile(as far as I know) but I was hoping some one with a lot more experience then me would have some suggestions on a Jellybean Rom or higher that would be appropriate for this phone.
Please if there is anyone here that may have some suggestions as to a better rom then Gingerbread, although Gingerbread is a vast improvement over FROYO2.2.1.
My main concern as I said before is getting better data service then 2G, I was told that Gingerbread would give me 4Glte but that has not happened even though I am only 2 miles from a T-Mobile tower, T-Mobile has said that this tower does serve 4Glte.
Is there an app that will improve my ability to get a better signal, I read somewhere about having to upgrade the phone's wifi ? to receive 4Glte ?
1: go to settings and choose LTE, if not possible, no 4g
2: if your phone can'tuse 4g (hardware) then the OS changes Nothing
Sent from my LG-D722 using XDA Free mobile app while walking
As a former developer/tester and long time user of this phone (I still have one to play with) it is not capable of LTE. The best you will get is 4G. I got 4G even with official 2.3.6. So if your not you may need to have your SIM upgraded at the store. The best Rom I've used is slim which is 4.0.4. I didn't like the stock launcher so I flashed Xperia launcher 2.06b and it was great. If you're stuck on having JB which is still buggy...Mirage was the most reliable. Daothanduy was the developer. Good luck searching and how this helped

I found the phone too slow to work with KitKat, but there were several solid Jellybean ROMs out there.
Read very carefully the upgrade threads and instructions as there are several low-level changes to the phone's firmware/software that are required to get off of "stock" and onto one of the KitKat ROMs. They're not "difficult" -- You just need to follow all the steps in the right order. Once you've got the right boot loader and are on an "MTD" ROM, changing between ROMs is reasonably straightforward.
Pick up a (paid) copy of TitaniumBackup Pro if you don't have one already. You'll be happy you did, even if it only provides piece of mind.
If the phone isn't rooted already, you may need "ODIN" (Windows only) or, my preference, "heimdal" to flash parts of the phone.
Anything you read about "WiFi performance sucks..." is likely only based on the visual indication of WiFi signal strength (RSSI) changing from the early releases to the custom ROMs. From what I could tell through actual throughput testing, there is no difference except for the RSSI.
It's a solid phone, though don't expect the GPS to lock reliably. There isn't a software fix for it, no matter what some claim. As far as I could tell, it was an RF-design or -execution problem. I have seen some threads suggesting some mechanical fixes for the antennas. I never pursued them so I can't comment further.
You're correct, it was only sold through T-Mobile. Official support for it was dropped like a rock when Apple won its infringement suit over Samsung. This was the phone that had all the infringement-claim boxes checked. Yep, you own a piece of patent-law history!
Samsung's source-code drops were horrendous and many of us worked to get subsequent versions of the kernel to run on the phone. As alluded to above, there were no upgrades to the proprietary binaries after the Gingerbread ROM.
I've still got one in the drawer, but it would take over three minutes to boot KitKat, so it wasn't terribly functional as a day-to-day phone.
The AMOLED screens do yellow with time. It's not your eyes
My main concern is getting better then the 2G I am presently getting, I have checked and I am getting 9 signals of different strengths I on occasion get3G bu it shows no bars during 3G and does not appear to connect during 3G.
I have up to 4G available in my area but this phone only wants to use 2G.
I did upgrade from FROYO2.2.1 to Gingerbread 2.3.6but I am thinking the modem in the phone is still the original that used FROYO.
At this point I am trying to find a upgrade or new modem software for this phone.
Any ideas?

This info might be old, but check out: http://forum.xda-developers.com/showthread.php?t=1192436
Thanks to @DickyG for providing that link to the available modems. There haven't been any new modems in many years.
My recommendation would be to upgrade to one of the JellyBean or potentially KitKat ROMs and use TWRP (my preference) or CW recovery to make it "safer" to flash modems. The "best" modem depends somewhat on carrier and location. I personally found the KG4 modem to have the best performance for me of the modems that supported splitting long SMS messages.
The SGS 4G supports HSPA+ (and not LTE) as it's "best" connection. There is nothing software can do to get LTE.
HSPA+ isn't bad at all. I typically got 3-10 Mbps on T-Mobile in the San Francisco Bay area. Once you have decent bandwidth, the most important thing for "responsiveness" is latency. See, for example http://www.dslreports.com/speedtest and http://www.bufferbloat.net/ A higher-bandwidth connection doesn't help that and, in some cases, the higher-bandwidth connections seem slower as they have more latency (often due to the carrier's buffering).
While some "stock" ROMs (and a few custom ones) have been "tweaked" to show "4G" in the UI, it is just cosmetic.
I am trying to get a better signal then 2G, I ran some test and have 9 signals available, but when I change off automatic to get 3G I get 3G but no bars. there are towers within 2 miles of me and I know for a fact that at least one maybe more are T-Mobile towers.
his has been a very long confusing journey it took me several months of contacting a agent at T-Mobile support before one took the time to give me the Kies mini to upgrade to Gingerbread, others would say there are "NO UPGRADES AVAILABLE FOR FROYO 2.2.1, most were to lazy or not knowledgeable enough to find the answer for me., I have tried but ever since that one agent I have not had any success with support other then here.

T-Mobile isn't going to help you any here as all they have are the "official" releases which stopped with Gingerbread several years ago.
You'll have to read how to flash a phone with a custom ROM if you want anything more than what they provided years ago.
I much prefer Heimdal to Odin for reliable flashing of phones. Some swear by Odin, I swear at it, especially as it is Windows only.
I'd suggest backing up all your data with TitaniumBackup Pro, as well as a "nandroid" (TWRP or CW recovery) backup. The read all the instructions twice or three times until you understand them and flash a custom ROM, including a matching kernel. I'd suggest a JellyBean ROM to start with. I'd also suggest moving to an "MTD" ROM and kernel to start as you'll end up there anyways (most of the more recent ROMs and kernels built for the SGS 4G were MTD).
You can then very, very carefully and selectively restore your TitaniumBackup data, making sure to set "Migrate system data." Restoring across major OS versions is possible, but you have to be careful how you do it. I'd make sure I understood how TitaniumBackup Pro works and the suggestions from them and others on how to restore data.
In your opinion does jellybean or Kitkat have a better modem?

All the modems for the SGS 4G are from the "official" ROMs from Samsung/T-Mobile/Wind for Froyo or Gingerbread.
There is no such thing as a "JellyBean modem" or "KitKat modem."
