4G Wimax radio bug? - Epic 4G General

Has anybody else noticed this behavior:
* You establish a 4G connection someplace with rock-solid coverage. Then, to keep the connection busy, you go to Youtube using the browser spoofing a desktop PC, and start watching a video that for whatever reason can't be watched with the official Youtube app.
* You move more than a mile or two. Connection remains active, even as you move through areas where you know from experience it's difficult to establish a NEW 4G connection if you don't already have one.
* Literally, as you're approaching another tower, the signal meter goes from 2 to 3 bars, you can almost reach out and touch it... and the 4G connection drops.
(at that point, for the sake of science and experimentation, you stop moving).
* If you do nothing, the phone will stew in 3G for a few minutes, then eventually try to reconnect... and succeed immediately with a strong, solid connection.
* If, instead, you swear angrily and manually toggle 4G off and on, it will immediately reconnect -- also with a strong, solid connection.
?????????????
I'm pretty sure the forced disconnections are by design (I think Sprint/Clear does DHCP and assigns IP addresses tower by tower, will only route them between towers as long as you remain within one or two hops of the tower where the connection was first established, and will forcibly disconnect the moment it sees that you're far away from the original tower and solidly within the coverage area of a different one. It would suck royally, but wouldn't be a bug per se), but I also think the fact that the phone doesn't realize it was disconnected in the middle of a strong-coverage area and try to reconnect immediately is a bug.
My stats: 2.1-update1, S700.0.55.DI18, hardware D700.0.5

Terribly poor Wifi connection

hello all, new to this forum so please any noobness that spurts out of my fingers.
Basically, I'm sat next to my wifi router and the legend can pick it up, "excellent" quailty apparently but it refuses to connect, always saying "obtaining address..." but always ending up being "unsuccessful".
Now, i was connected this morning when i was in a different room with only 2 bars of signal, but now i cant connect at all.
Cany anyone help/similar issue?
Try to restart the router.
Is your network secured? If yes, WEP or WPA/WPA2? If it is WEP, it may be just incorrect WEP-key.
My network is secure, WPA yada yada.
However, i'm now going through a stage where connection is no problem! Might just have been a one-off rough patch, or maybe its something to do with the legend itself? Some reviewers did comment on the questionable wifi signal/strength - most likely due to its construction maybe?
Well them im glad that my signal strength is extraordinary.
I still dont understand this..
I was at work, connected with our thomson (TG712), when i left the hall and went to the canteen.
I usually disconnect when reaching ±15 meters (this distance is why im so happy with this phones wifi strength), but this time it kept a connection while i was in the mess
With the weakest signal strength but still, I was able to download properly :/
This mess hall is about 50 meters away maybe more and with walls in between
Yes the SSID was our thomson and No I didn't get this working again but how the **** do you explain this.

Badly need of help: wi-fi issues - bad signal, droping connection

Hi,
I have huge issues on my TF with Wi-Fi, I am really despaired with it. Signal strength is weak even if I am standing very close to my router - on default wi-fi icon it shows 2 sections of 3 and Wi-Fi Analyzer says signal is -55db. Few steps away it drops to -63db. And If i decide to go to another room signal stays around -66db and connection drops in and out like hell, sometimes it just can't connect at all for minute or so.
First thing I was thinking it's my router transmitter is week - it was abit old, but I never heard problems with it before. So I bought new router 300mbs N router with 3 antennas and very good signal. This not helped at all. Signal strength shown by Wi-Fi Analyzer remains pretty same with all other problems.
I've tried various wireless settings - b/g/n only, various channels, security on/off etc, I've tried various ROMs - not much difference. I am beginning to think there's some hardware malfunction on my TF but still hoping I missed something. May it be that TF is performing badly with this exact router? My Nokia Symbian phone shows excellent signal strength overall whole flat and I don't have any disconnects sitting in farthest corner.
Any advise welcome. Thanks
i have a Samsung galaxy tablet (the original). using wifi analyzer, the transformer consistently has a 10 dBm lower signal level than the galaxy.
I hadn't compared the signal level with my Incredible, but looking at it side by side also shows the 10 dBm lower signal...

Note 2 not automatically switching to stronger WIFI signal?

Ok this may be kind of a long post but I'll first address what I think is the issue.
My note 2 doesn't appear to be automatically switching to stronger available wifi signals unless I manually toggle the wifi off then back on again. It will then connect to the stronger signal.
The reason why this has become an issue is because I bought a Diamond WR300n wifi range extender. I'm using it as a reapter. I want to have better wifi signal in my garage where I spend a lot of time. My current wifi signal drops off pretty much near the garage when using my phone. My laptop still gets decent wifi reception when I'm in the garage though.
I went through the fairly basic setup for the extender and got it working. I confirmed this by plugging in the ethernet port from the extender directly to my laptop and its receiving a signal just fine, browsing the internet etc.
So i put this extender in my garage, it connected normally and I confirmed it was working using my laptop again. Everything appeared to be working fine. The extender has the same SSID as my main wireless router (uverse 78wireblahblah).
The issue is when I'm inside my house I'm connected to the main wireless router because this is obviously the strongest signal. When I walk out of my house the signal diminishes as I approach my garage. I can walk into my garage and my wifi signal is pretty much gone even though there is this repeater putting out a working wifi signal with the same SSID as my main router.
Weird right, one would think it would automatically switch and connect to the repeater in the garage, but it doesn't.
Now if I manually turn off wifi and turn it back on while in the garage, bam, very strong signal and I'm connected. There really is two issues though, 1. my note 2 is not automatically switching over to the stronger signal (both the repeater and main wireless router have the same SSID) in the garage and 2. sometimes it connects to that stronger signal in the garage from the repeater (only after i manually toggle wifi off and on) but the internet doesn't work. I'm actually connected to my network because I can access my "Yamaha receiver app" that lets me turn up volume etc on my receiver but I don't have internet access etc. This is usually the case but after awhile it just seems to start working and I have full internet access.
I know this is only semi phone related but I figured since alot of guys on here are very savvy with this tech stuff, maybe someone could help.
Again
1. why won't my note 2 automatically switch over to that stronger wifi signal which should be the same in the garage.
2. why does it sometimes only connect to the network but doesn't allow outside internet access.
Should I try the "wifi jumper" app that supposedly auto switches to best wifi signal (i thought our phones do this anyways)?
Not sure if this is the right place to post this so please move if need be =)
Thoughts?
Stay on what Samsung preset.
Basically I owned a nexus s, it does have automatically jump to higher signal router or access point in android 4.1+.
So basically the WiFi just jumping from my router to access point and from access point to router and I ended up getting no WiFi signal. I have to switch off my access point (extender) to get my WiFi working again...
And note 2 won't give me this problem.

If you'd ask me, just buy wifi jumper, you won't regret it!
It works perfectly fine with my 4 routers, all with different SSID. It's nice to have the best signal available wherever you are in the house. Wifi jumper gives me the best results I have had since trying a few different apps like it. The owner just finished rewriting the code for connecting to different routers with same SSID, so it should be the perfect solution in your situation!
And no, I'm not affiliated with it in any way, just a happy user :thumbup:

wifi jumper is a good idea

Yeah, Wifi Jumper is probably the way to go. In an ideal world, the WiFi stack would roam properly in all cases, but sometimes you're just not quite far enough for it to roam. This is even an issue with the PC also, but most manufacturers allow you to configure the roaming behavior of the driver to your tastes (max range or max speed).

Wifi not reconnecting

What happened:
I am using a new Nexus 4 in various buildings on a campus (specifically, the University of Washington). For simplicity, let's assume that there are just two buildings, Building A and Building B.
There is a strong WiFi signal within both buildings, and I can connect to the WiFi network in either one. When I walk between buildings, the signal drops outside, and the phone switches to 3G networking (as expected).
Once I'm inside the other building, however, the WiFi does not always automatically reconnect. Instead, the phone will often remain on 3G mode, despite being in the presence of a strong WiFi signal.
If I restart the phone, the phone will then reconnect to the WiFi signal. Unless I do this, however, the phone will remain in 3G mode indefinitely. This drains the battery and results in high data usage with my phone plan.
Steps to reproduce the problem:
1. Connect to campus-wide WiFi.
2. Walk outside. WiFi connection will drop, and phone will switch to 3G.
3. Walk inside another building. Phone will remain in 3G mode, rather than switching back to WiFi, despite being in the presence of a strong WiFi signal.
4. Restart the phone. After rebooting, the phone will now connect to the WiFi network.
What you think the correct behavior should be:
The phone should automatically switch back to WiFi when in the presence of a suitable WiFi signal. A manual restart or manual reconnecting to the network should not be necessary.

Did this issue occur before you were on PA rom 3.5?
If it didn't then I think it could be the rom if it's not then it's the school's wifi. It happens to me when I'm on campus too and I found out it the school's WiFi network was getting hammered and the signal was disrupted. No clue how that any of that happened.

Hi, I have the same problem. Did anyone manage to solve it? I have my Nexus 4 since yestereday and it's not reconnecting to my home wifi. Previous phone HTC Incredible S didn't have this issue and since that phone my wifi settings wasn't changed. I have AirLink AP, no name router and wifi is encoded with WPA. But i don't have to restart the phone to reconnect. It's enough to turn wifi on the phone off and on in settings. But it's really annoying. Thanks for hints.
And please excuse wrong expressions, I'm from Czech republic
Edit: I have stock rom, JB 4.2.2

WiFi Connectivity Intermittent

What are some particulars why my G3 is suddenly getting intermittent wifi at a certain range when it's been in the same room for years and never had an issue? It was working fine before and now it cannot sustain wifi connection despite "showing" an initial max/good signal, especially when it starts initiating such as loading a video on YouTube. However, it works fine when in close range to the router which makes it confusing if it's the WiFi antenna hardware already or some sort of new interference.
tl;dr
1. Works fine when near the router. No connection loses. WiFi signal in my room is good/excellent regardless.
2. WiFi SSIDs show up, then remains SAVED, the says no internet, then randomly connects and works.
3. Connection drops the moment I open a YouTube video, load an app, etc. basically when there is loading involved.
4. Phone has been in my room for years so the range is good and consistent.
5. Other devices can see the WiFi connection just fine, it is just this phone recently that showed a problem suddenly. WiFi signal at good/excellent for every other device.
6. There are other WiFi SSIDs of neighbors but only around 3 or so and they've existed for a while already. We are also in the appropriate channel away from theirs via WiFi Analyzer.
7. The router signal strength is able to reach even up to the house beside ours in the garden.
What I tried:
1. Reset network settings via Backup and Restore.
2. Changed ROM.
3. Removed Blokada / VPN. Private VPN is off.
4. Turned on Airplane mode, then turned on WiFi.
5. Channel WiFi channel, router Mhz, connected to 5 Ghz.
6. Removed Bluetooth devices in the area, Bluetooth toggle at off.
7. Went near the router to connect, it's sustained, then walked over to the room, connection drops. Other devices sustain it.
I understand the phone is showing its years but curious what could be possible reasons for this new issue to appear.
