If it happens on every single rom you you installed, then apparently this is a hardware fault.
What "Base" do the Roms, you installed, created on?!
I mean based on what version of RUU?

I don't think it's a hardware fault, disabling the fast reboot setting and rebooting device solves the problem at home, wifi or data connection won't disconnect. Sill can't connect to my router at work.

I've tried 1.26 and 1.28 version. If it's a bug and it has not been addressed then it's very likely that the problem will persist.

It will sure solve the problem, after rebooting with fast boot off,
Wait till your battery falls below 10% and tell me will it still sustain the connection or not?

Some people on other threads reported the following, changing wireless settings on the router:

Disabling N-Band and reverting to G or B bands solves the problem for some.
Going to WEB encryption and abandon WPA/WPA2 solves the problem for others.
changing the channel width to 20MHz (Lower than channel 11, the default onmost of routers with N-Band) solves the problem to others.

At work I cannot change so much settings as the general rule is "if it's working then don't touch it" and it's working for most of our clients which is one of the main reasons the wifi router is there.

Today I'll let my battery go below 10% while I ping my phone. So far, pinging gets a bit unstable when the screen is off, but I don't lose packets at all. You can notice the difference as soon as you turn on the screen, ping time is lower.

Thanks for the tips.

When below 10% give it exactly 15 minutes on sleep mode,
and try to ping it again,
Most probably you'll loose the packages and connection as will,
Mobile network will kick in for 5-10 seconds and will disconnect.
If you unlock your phone exactly after 20 minutes starting the time you first put it on sleep mode, you'll notice no data connection at all on the Notification Bar!!

Please do this before changing anything on your router and report back wither the problem regenerates or not!!

Thank you in advance..

When problem regenerates:
Turn your phone completely off
With "fast reboot disabled"
Charge it, for good time, to make sure it exceeds 10%
Turn it back on
The problem will be gone, till battery falls again below 10%.
I always charge it all the way up to 100% after restarting it
Good luck

Ok, when the battery was 9%, I left my phone alone and waited 16 minutes. Tried to ping, no answer. Turn on phone, WIFI has been disconnected and I had no data connection.

As soon as the screen turned on, I could see data connection firing up and some seconds later wifi started also and connected to my network at home. Now I turned off the screen again and I'm waiting another 15 minutes while I ping the phone.

I'm using Insert Coin ROM in case you want to test it.

EDIT: waited more than 15 minutes and wifi was still working.

Thank you for your feedback,
Give it exactly 20 minutes, then ping,
I know this is time consuming, and I've been there believe me,

I'd be so grateful if you could provide your WiFi router's settings:
Band (N, B, G, mixed B/G)
Channel (6, 9, 11)
Security encryption (WEB, WPA, WPA2), (TKIP, or AES)

Thank you

Healthy WiFi Router Settings - Mode: B/G Mixed - Sustain connectivity below 10%

I have modified the WiFi Settings on my CISCO-Linksys WAG120N
To the following (Please refer to attached pic)

Network Mode: B/G Mixed (No N-band, N band is disabled)
Radio Band: Standard (20 MHz channels)
Standard Channel: 9 (2.452 GHz)

Results:

Healthy connection during the whole day WiFi, and Mobile network
When battery falls below 10% and the "Low Battery" alert pops up, the connction stayed on and no diconnections at all
Restarted my phone and monitored, the connection stayed on with no disconnections
The monitor was held over periods of test awakening after sleep mode (15 min, and 20 min)
Disconnected from WiFi and monitored the Mobile network to be connected over periods of test awakening after sleep mode (15 min, and 20 min)

****NOTE****
The tests were held under the following conditions:

Only applications that came with the phone are the ones (Installed/Updated)
No other apps were downloaded during the test period
No Bluetooth devices were paired during the test period
[*]WiFi Encryption protocol was unchanged "WPA2 Mixed (TKIP or AES)"

Experiments to continue:
I will continue this test, but will use other router WiFi settings,
I will monitor and give a feedback.

Hope above helps.

Conclusion - Do not use wide channel N Band (40 MHz channels)

As most of nowadays routers have N-Band capabilities with 40 MHz channels width,
It's now clear that the driver of the WiFi modem is the problem.
It cannot sustain connection over N-Band 40 MHz channel width, when battery falls below 10%.

Conclusion:

Always set your router to Standard Channels with 20 MHz width.
If you know that the router you'r about to connect to is N-Band, try to keep your battery above 10%, if the battery is about to get below 10%, disconnect from the N-Band router immediately to avoid conflicts on the driver and avoid restarting.
You can charge your phone to a decent amount above 10% and then reconnect to the WiFi N-Band without any problems.

Update:
I used Channel: 11 B/G Mode, Standard 20 MHz,
Fault regenerates.
I'll revert back to channel: 9 B/G Mode, Standard 20 MHz

Hope these information helps

Hello all.
The wifi and mobile data disconnect for me too when i leave screen off for a long time i.e. 15-30 mins or so.
Mind you that this happens regardless of the battery left... It even hapens if the battery is full..

Hello DanteGR,

My analysis was based on the stock rom.
The latest release of it specifically.

I suspect you haven't shut-down your phone with "Fast Reboot" disabled.
Here's what to do:

While you're connected to the WiFi network, you have a problem on, go to> Settings> WiFi> And long press on the router's name> Select "FORGET".
Go to Settings> Power> Un-Tic "Fast-Reboot"
Now long press the "Power" button and select "Restart" and confirm the prompt.
Wait till your phone restarts and fully load Sense give it 15-20 seconds un-touched.
Go to> Enable WiFi> Connect to the router you need.

IMPORTANT:

Do this ONLY when your battery level is above 10%.
If your router's WiFi is an N-Band, try your best not to have battery drops below 10% while you're connected to the router, the problem will simply regenerate.
Before dropping to 10% disconnect WiFi from your N-Band router immediately.
Charge your phone to over 10% and connect again, or leve it in charger and connect again,

Please monitor 15-20 minutes of connection on sleep mode.
Please give us your feedback,
Thank you!
Hope above helps.

Thank you very much for replying my friend

Well to tell you the truth, diabling the fastboot option in power settings is one of the first things i do when flashing a new rom because i want my device to restart from scratch every time i reboot so that shouldn't be the prblem right?
It has been nearly a whole hour now that i have been connected to my wifi at home (screen off all this time) and it has not disconnected yet. I'm at 60% battery level so i will see if it disconnects if battery gets lower.
Last night though I am pretty sure that i was at about the same battery level and it got disconnected ny itself.. That's some strange stuff mate

Weird thing is why does the mobile data also get disconnected when wifi does. Maybe it's a more general deep sleep phone problem?
If I get disconnected again i will try ur suggestions step by step and see where that leads me.
Thanks again

Any time and will be waiting for your feedback.
I noticed that you have the same exact Radio version on your phone, even with the custom rom, as mine on the stock rom.
Maybe it's a Radio bug, maybe HTC will find a way to update radio.
Good luck.

Ok will do.
But I want to add two things.
Firstly, I want to ask ur opinion as to whether this is a hardware fault or not. Reason I'm asking is because i'm still in the DOA period and can take back the phone to change for another new one.
Secondly, I don't think the problem is only router/wifi related because mobile data also gets switched off when the problem appears. Am I right in saying that?
But then again, if it is a software fault why don't all users have it??
Very confused

Sure, I totally agree, and I'd go for a hardware fault,

The problem is that I haven't got confirmation from other users that they have encountered the problem!!

Maybe it's there and they do not know,
Bear in mind that not all users leave their phones to drop below 10%
Not all users connect to an N-Band wifi routers!!

See how unique the problem is!?
I will keep on searching for other users with exact same unique case and will ask them to report back if they have the problem or not...

UPDATE: So far today i am at 41% battery and wifi has not disconnected yet when in sleep mode (fingers crossed
