Radio troubles

Hey guys great news on our own section! Do any of you notice wireless dropouts? I have the wifi on whenever I'm at home and it will drop out quite regularly probably once per hour. I also notice that the gsm meter will go to 0 bars when I turn the wifi on our off and on other occasions. does anyone else see this kind of behavior?

Wifi Drop-outs
Yep, I also notice dropouts. Usually it's not a problem for web browsing but it is annoying when it stops youtube playback (which often happens).
From looking around I know that there are some others that also have this problem.

I thought there was something in "settings" to switch off wi-fi sleep, or am I thinking of my Xperia X8? Certainly my Ideos X5 shuts off its wifi after a few minutes, and yes, it is annoying.
Try installing a battery power manager app from market, there might be a "wi-fi stay on" in that ... maybe THAT's what I did to cure similar behavior on the Xperia.

some people (in chinese forum) mentioned it could be due the router's (i presume u r using one) incompatibility with the wifi module..
try changing to another router may help, if possible..
others hinted that flashing the malaysian 136 rom solved this problem..
u may try at ur own risk..

Wifi Sleep Policy/Static IP - possible solution??
I had this problem while at home on the network and this worked for me:
In the advanced settings Menu of Wireless/NW is WiFi Sleep Policy in which there are 3 options:
When screen turned off, Never when plugged in and Never. Mine was set to the first one so I chose Never.
Next, Use a Static Ip - enter settings and reboot
IP settings are also on this screen along with the MAC address.
This has solved the problem for me and have certainly noticed an improvement on battery usage, an added bonus for sure.
I don't use mobile data (or try not to!!) so not sure in what way a static IP would affect that.
Great to have a forum for the X5, many thanks XDA

I've noticed that if the GSM signal drops out it can lock up both the Wifi and Bluetooth as well.

advanced settings for wifi -> never sleep works like a charm

Yep the static ip fix worked for me, thanks for that. I had done the Never sleep selection but did not notice an improvement. As @trk pointed out on Whirlpool, the static ip Fix is of limited use if you use several wifi access points regularly. I only use mine at home so it's great.
Did the OP get a result with this?
Now to tweak it so that annoying warning stops popping up about causing traffic etc.

大家好，在这里与大家真诚交流。

Don't know about wifi, cause I don't use it but 3G is doing it. It just can't connect to any network, even there is very good network available. When trying manually search it doesn't find any networks. Sometimes even rebooting doesn't help.
My two friends have same phone and they says that their units are also dropping connection. They have solved it by forcing device to 2G, but I live in area where is only 3G 900MHz available.
Hope this will be solved in future updates or by coocked rom.

Problem with Nook Color's Wifi

I have a problem with my Nook Color's Wifi.
I received my refurbished Nook on Monday, and installed cm7 that night. I've got it overclocked at 1.2ghz and running smoothly for the last 3 days without any hangups or any other signs of problems.
The wifi was working great until this morning. Now, when I turn my WiFi on, it hangs on the Connecting... notice under Wi-Fi, and it eventually goes to Disconnected, and none of the nearby networks show up. The message then continually cycles between Connecting and Disconnected.
I was wondering if this was a fixable problem? Or if this is a damaged hardware issue.
I've taken a (bad) cell phone picture of the WiFi screen where it shows both the Connecting... message and Disconnected one. The top network "Commodore" should be active, and both my laptop and phone are connecting to it just fine right now. I've attempted rebooting and turning the device off for 15 minutes.
I'm really hoping I don't have to return and exchange, because I really like the Nook Color, but without WiFi I just simply can't use it.

1. activate wifi
2. go to wifi scanning
3. remove one secured SSID
4. add a secured SSID: generally your own one.
It disable airplane mode and everything is back online.

[Q] T-Mo G2 Rooted/Stock OTA 2.3.4 Wont stay connected to wifi

I tried searching and I've not found this issue addressed, but I may just be doing it wrong. But, here it goes anyways...
This house has 3 T-Mobile G2s, all with the same OTA. Only mine is rooted. However, none of them will stay connected to wifi. The wifi icon is showing up and it says that I am connected to the access point, but in status it says that mobile network status is disconnected. I can't do anything data related after it times out. If I disable and re-enable wifi it stays connected for a bit before it goes dead again. The handset doesn't go into sleep/screen doesn't turn off. Before I updated I did a Factory Data Reset, then re-entered all my information then let it update. Is there anything I can do, or try?

Being that all 3 phones cannot stay connected I'd be inclined to say look at your router... I'm assuming you've done all the obvious things like reboots, battery pulls, "forgetting" your network and then re adding it? Are other devices in the home able to maintain a wifi connection... your computer, for example? You've tried resetting your router?
If the screen isn't timing out, have you checked your Display settings? What makes you think the screen timeout is related to the wifi problem?

Well in the past on my myTouch 3g... wifi at times would get wonky after the screen timed out/it went to sleep. So was just adding that information here. Yeah, there are at least 8-9 other wifi devices here that can connect to the router just fine and send/receive data. I've tried "forgetting" the access point and then re-adding it, resetting the router, battery pull... and the same thing happens. And the router doesn't have MAC address filtering either. Can't ping google.com or 72.14.204.105 from the phone, but my pc can just fine. If I disable wifi it works as it should. Its just I only have realllly slow EDGE service in the house.

Hmm... by default wifi should turn off when the screen times out. Unless you've changed the wifi sleep policy. I had mysterious wifi trouble before on a different device (endless "obtaining ip address" loops) and the only thing that worked for me was restoring an older nandroid. Obviously, you're no longer rooted and that's not an option... but it's super unusual that 3 G2 phones are experiencing the same problem. And they're all running the Gingerbread update, so maybe that's the common denominator. I'm sorry I couldn't be more helpful. I'd definitely pay T-Mobile a visit.

I've not messed with the wifi policy, but my last phone would just drop wifi completely and I had to forget/re-enter everything to get it back. If it was the update then I would think the problem would be more widespread. Going to try fiddling with the router some more since that would most likely be where the issue lies. All else fails will just rollback to an earlier nandroid, like you had to do, and seeing if I can't get at least mine consistent. Thanks for your help and letting me bounce ideas off of.

3g fallback for internet on wifi?

So I'm having trouble with getting wifi how I want it on my phone. At work we have a unsecured WAP with a web based authentication page. Trouble if you ever use it, it remembers the WAP and wants to login, but unless you you goto the web page, you have no internet. This is particularly a problem when wifi sleeps and looses connection.
The big issue with this is that my phone assumes it has internet when it doesn't. It doesn't fall back to 3g on failure to connect. That means I will not get texts for hours, facebook won't update, etc, etc.
Is there a way to force the phone to fall back to 3g when it fails to connect via wifi? Alternately is there an app that will parse a wifi login page and auto login for me? I'm running clean GB right now.

If wifi was active it should stay active there is an option to keep wifi on in the settings that way it wont go turn off/ go to sleep while its connected. Change the wifi sleep policy this will keep it from "disconnecting".
Settings>wireless & networks> wifi settings> press the menu button advanced> wifi sleep policy> Never

That's not the big problem though. If I lose connection (easy enough with out concrete walls and walking around) or simply don't login in first thing in the morning I still have the issue.
I either need a fallback to 3g or a way to auto login.

well i can tell you what i use Juice Defender and When WiFi is once it goes off my data kicks in so yeah that's my fallback to 3G so you could give that ago if you want.

IMO
Juice Defender= Battery Drainer and waste of money when i can do what it does manually.
To the OP:
the phone should automatically go back to 3g when wifi disconnects i just tested this with my router i had it connected then pull the plug and it went to 3g.

ive done some tests without JD also helps in other areas BTW, and to let you know i put JD on Extreme and let no apps get data unless i manually toggle data and i can tell that my battery lasts much longer by at least by a few hours but still helps rather than my data always being funny randomly connecting and disconnecting to 3G or even if it was off JD does help.

It does when it disconnects, however since the wifi point is open it auto connects every time it picks it up again. Aside from manually forgetting the wifi point all the time, there doesn't appear to be a way to stop this. Connecting remembers it. Its not that I can't get around this manually, but its really annoying.

You could probably do something with a tasker profile. I don't know how to do it but they have a bunch of examples on their site that may help.

I see your problem. You may be able to do this using scripting. The closest thing I have ever done like this is write a script that logged into my cable modem admin page automatically and grabbed the signal strength to log it. I used PHP (command line interpreter) but I would think any language should be capable of submitting data via a post request. Mine was triggered by cron. You would need to trigger on a successful wifi connection, check the ssid, and go from there. I dont know enough details about how that part is done to be helpful, but I know there are some apps that do detect active wifi connections (samba comes to mind) so it must be possible.

Good suggestions so far, u could also try spare parts wifi sleep policy settings..
It might also be something where the connection on the wifi network's (not your phone's) end times out, in which case I'm not sure what to tell u.

DON'T USE THEIR WIFI! Problem solved.

WiFi not working after extended periods of non use

So what I'm finding is that if my tab sits on the charger for a long time without using it, when I go to use it the wifi icon is gone. When I go into wifi settings, it says my network is not in range. To fix it, I have to toggle wifi off and then back on, and then it gets on my network just fine.
Anyone else have this problem?

Have you tried changing the wifi sleep setting? Worked for me, I believe it is under settings-asus customizedsettings- wifi sleep settings

really odd. Outta ideas already lol. Good luck!

I had this issue with my TF101 after not having the issue for 2.5/3rds of the time I owned the TF101. Initially I thought it was the TF101 but I narrowed it down to the router.
A) I had implemented a policy on my router to restrict the number of IP addresses it can "assign" to connections. In this case it was set to then and there were more than ten devices connected to the router making it impossible to assign an IP address to the TF101.
B) It could have just been something with the router I wasn't aware of as resetting the router always fixed the issue. Though this could be explained by saying resetting the router resets all of the connections and opens up a spot for the TF.

In Android phones you can use the secret codes
If you have the phone apk installed perphas you can use this:

I have noticed that when my 300 is sleeping for a while, my email will not push/ sync. When I wake my tab up, Ive noticed the wifi icon is gone, but will come back in a second or two. Ive never had to toggle the wifi however.
And yes, Ive made sure the Battery Saving setting is unchecked to not suspend network connection while sleeping.
