This issue has been annoying me for quite some time, and after a lot of searching (and trying stuff) I've decided to make my own thread because nothing seems to help.
Let's say I'm at work and I turn on my phone's WiFi radio, this makes it connect to the work WiFi without problems. Now once I go back home, the network becomes out of range so it switches back to 3G/4G (so far so good). But when I actually get home, it takes 10-15 minutes before my phone finally decides it can connect to the WiFi there. I have certain appliances that rely on my phone making a timely WiFi connection so you can imagine this will trip a few of them because I'm long home before it finally connects. I already tried toggling various battery/power/app optimisations found across this forum, but as mentioned nothing works. Pretty sure it's because Android scans for nearby networks only once every X minutes.
Now, I can "force" it to connect by just knocking on the screen to turn it on, but I either forget this or have my hands full and am unable to knock (and shouldn't be necessary anyways). So in short: is there any way to force Android to check for networks every X seconds/minutes instead? I am rooted, if that helps in any way.

As some TP2 or other WM device owners I've noticed that WM often seems to forget WPA passwords when using WiFi. It doesn't really matter wether you use AES or TKIP and how long your preshared key is.
In my case the symptoms look like this: After I create a WiFi connection (WPA2, AES, hidden) so that my Rhodium can use my home WiFi network, everything goes just fine. But then, after having established a connection for two or three times the troubles begin. Usually it takes about 3 or 4 seconds to establish a connection. But suddenly it takes about 10 seconds after which I get a warning that the connection could not be established. If I then go to my connection settings, I allways find them completely messed up, so that I have to select WPA2 and AES and reenter my password an so on. Well, after it happends to you for three or four times, this becomes extremely annoying.
Recently, however, I've found a kind of workaround for this problem. And here it comes: After I turn on the WiFi, I simpy wait for about four seconds. If WinMo behaves nicely, 4 seconds are pretty enough to establish a connection. If, however, I don't get connected after these 4 seconds, I IMMEDIATELY turn WiFi off, wait 2 seconds, and turn it on again. With 99% probability this second try gives me a working connection. If it doesn't, I simpy repeat the same procedure once again. So, the scheme is quite simpe:
Turn WiFi on and wait 4-5 seconds (it depends). Got connected?
Yes: O.K
No: Turn WiFi off, wait a second and turn it on again.
The main thing about this trick is not to let WinMo try to establish a connection for more than 5 or 6 seconds, otherwise it will delete your connection settings.
In my case, this workaround works perfectly. For more than two weeks I've been using my home WiFi with Touch Pro 2, establishing at least 4 or 5 connections a day and not a single time my connection settings were lost. Well, surely this thing with turning WiFi on and waiting and turning it off if you don't get connected fast enough is also a little bit annoying, but nevertheless it is much less annoying then having your connection settings all messed up every single day.
I'm not sure, whether this workaround will work with other devices or WinMo versions or even firmware versions, but may be it will help at least some of you affected by this odd problem. So you may just give it a try.
I'm using Touch Pro 2 with stock O2 Germany ROM (1.19.207.0)
Thanks for reading this long post and sorry for my bad English.
Excellent! Thank you for sharing your workaround!
I do something similar, except I turn wifi off by pressing the power button if the wifi hasn't connected in a few seconds. (By default wifi turns off when it goes into standby.)
On the odd occasions where the key does need to be entered again, I keep a copy of the wifi key "somewhere" on the device. It's a copy and paste operation after that, so it doesn't take long to re-enter the key. Luckily you can use the keyboard Ctrl-V method to paste the wifi key into the TouchFLO interface.
The other observation I've made, is that if I switch on the device by sliding out the keyboard, my Touch Pro 2 has a higher chance on getting a 'lock' onto a weak wifi signal. I'm not really sure why!
I'm glad that this workaround works not only for me
Actually, I don't use Connection Manager any more, for I've recently installed Rhodium Keyboard Controller GSM 1.3.2. Using this handy tool I remapped my Home button, so that double clicking it, turns WiFi on and and double clicking it with working WiFi turns wireless off.
I guess that Rhodium Keyboard Controller uses some advanced routine to activate WiFi, because since I use it for establishing WiFi connections, I rarely have to use my workaround, for normally I get connected on the first attempt.

A lot of times lately I'm losing my 3g Mobile Network, my signal strength will be a full 4 bars and I still get the issue. Usually if I reboot the phone it will come back. I'm starting to think it gets lost after it connects to WiFi and then when I disconnect WiFi. Anyone having this issue? If so, are there any tricks to getting this to stop?
My phone is completely stock 2.2, no root.
I'm not sure which of these events may have triggered my intermittent lack of 3G connectability but these are the only changes I've made since this started happening:
1) Upgraded to Froyo.
2) Performed the .dun trick to allow 3g Hotspot. (Although I never use it, I tested it a few times but this problem happens without the Hotspot turned on.)
Did you do a factory reset after the froyo update?
Sent from my Incredible using tapatalk.
Nope, I used the SD card method before I got the OTA. Have never done a factory reset.
I have this as well, be it im on a different carrier (Cricket) but it appears in all stock htc froyo builds.
My assumption is that is the radio being used. of how HTC's implementation of Froyo interacts with the radio.
I switched radio's and havent had it occur on me while in the OS yet, and it does occur sometimes on boot still, but if it loads on boot it seems to stay up and stable.
My trick is to turn airplane mode on for about 30 seconds (30 seconds after i see the airplane icon), then turn it off, i assume this reloads the radio, when the brings 3g back.
I can also read my nv settings with qpst and reflash them back to the phone with no changes, which causes the radio to reload as well, and 3g ALWAYS kicks back on.
Also updating the PRL (even if its the same PRL) seems to work as well (assuming this is due to the reboot, which reloaded the radio)
The radio i am using now is:
2.15.00.09.01 - Seems pretty stable, except the occasional one of at boot, which is fixed by airplane on/off.
From what i can gather this nothing to do with custom roms, as many offical Verizon customers on Official NON Rooted 100% completely stock phones have this as well.
Hopefully HTC/Verizon will fix this in a MR update.

Click to expand...
Click to collapse
I'm gonna try that next time it happens. Easier than rebooting, then it wont bother me too much.
I had that problem once, and never saw it again.
One problem that just happened for a second time today is I cannot send or recieve MMS. HTC had me reboot the phone and call VZW support, of course they yelled at me for not using a task killer -.-
The reset worked, but I'm going to get annoyed if this becomes a regular problem
I have same setup and same issue. As soon as I made the EPST changes for tethering and hotspot, I started having this issue where I'd lose my data connection completely after disconnecting from my wifi when I leave my house. A reboot of the phone fixes it but it's still kind of annoying. It happens I'd say about twice a week.
I have an interesting problem, I couldn't find this issue on anywhere else therefore I wanted to share with you;
Sometimes after 3-4 days usage (in this time period sometimes I use wireless, sometimes 3g or sometimes turn off the connection), my phone gets stuck on edge connection and never goes to 3g unless I restart it.
I tried switching air plane mode on/off and several other things. Only restart fixes this. This is not a new issue, it is happening almost for 6-7 months (on 2.1 and 2.2). It doesn't matter much to restart in a few days but I wonder anyone else has the same problem.
Am I the only one ? surprised
I am on my second International HTC one X and both devices would lose the carrier signal quit often... I would either go to airplane mode, or turn the network off and on and it would grab it again. Sometimes it would be good for the day and other times, I would have to do it a few times....
I wanted to think it was my carrier having issues (MTS in Winnipeg MB Canada)... however, this has never happened on my many other devices. Now I wake up today and turn on the mobile data, after awhile... it does not connect, under settings it says disconnected because service is unavailable. I tried reboots, restart, airplane mode, checking apn settings.... on my last reboot, it says No signal/emergency calls only.
So now I am fearing a hardware issue (but I find it odd it happens on both my one xs).
I love this device and aside from this potentially huge issue.... I have no complaints, so I will ask here and see if you guys have any solid input.. before I contact htc!
I also popped my sim in and out, as of right now...
Thx in advance.
**update: it almost seems like putting wifi on, knocks out my carrier signal.... after an hour of doing the above things, I turned off wifi, went to airplane mode and now my signal and data is there (it makes no sense) and it is quite a hassle
The weirder part is, it seems to only be in the morning.... once I am up and running, I do not seem to have many issues through out the day, but If I put wifi on long enough... It goes to no signal/eventually....
If I do not put on wifi, it either does not drop.... or I am not noticing.
I've just begun having network problems but I'm not sure it's related to your situation. I'm in Australia on the Optus network.
It happened suddenly yesterday. Service completely cuts out for extended periods. It will occasionally come back on for a short while (long enough to download all my sms) but will then cut out again. When the signal does briefly come back in, the signal strength is decent: it's an all-or-nothing proposition.
Did you manage to resolve your situation? Would be interested to know what resolved it for you.
I've had this phone since early April when it was released here and the is the first issue I've had with it. I haven't done anything new to my phone in the past week so I'm finding this strange. I'm running Leedroid 4.0.0 but I've had that installed for weeks without issue. I'm worried it could be a hardware issue.
I'm going to try reflashing it tonight to see if it's a software issue.
So I just purchased the tablet brand new about 2 weeks ago. Love it for the most part!
Over the past couple of days though, the wifi has really started to act up, and it's passing me off.. About every half hour or so, sometimes longer, sometimes shorter, the wifi will just stop working for a while. The bars will still be there, as will the little "download" and "upload" arrows lighting up as though data is still being sent and received. However, the wifi just isn't working. Pages won't load, speed test . net app won't work, nothing requiring wifi.
I usually have to go into wifi settings to disconnect and reconnect for it to start working again.
I haven't done anything different to my wifi router, and my other wifi connected devices don't seem to be having any trouble staying properly connected, so it doesn't seem like it'd be an interference issue.
Can anyone provide me with some help?
