So recently my friend had spilt Coca Cola on my phone, and, a few days, my WiFi became very weak and extremely hard to keep. After fidling around with ROMs for a while I found that certain ROMs were able to hold the signal better than others, but then when going back to others it was back to weak even though my 3G works really well. Is there any fix for this? Would opening up the phone and cleaning the inside possibly fix my issues? Isn't the 3G and WiFi modules located in the same area (just wondering why the 3G isn't messed up but WiFi is)?

I'm running Damage Control 3.2.3 since I got the Evo about a month ago so I don't have too much time running the stock ROM.
I've noticed the wifi signal sucks! I can be using the wifi sitting on the couch a few from the router and my signal dropouts out every so often. I'm also running the latest radio (2.05.00.06.10).
Anyone have wifi issues?

Mine isn't THAT bad. But I have noticed the signal seems abnormally lower than other devices. And there are places where I can't even see a wifi signal that other devices can see and connect to.
Anyone have any insight as to why our Evo's arent good with Wifi Reception ?
problems with wifi, reset router.
I had problems with my wifi signal. thought that it was because of my flashing back and worth from rom to rom. Finally, decided to reset my router and voila! signal problems were gone.
this is totally non-specific to a router.
My laptop had full strength. My evo has one bar. Same thing at home, other people's homes, hot spots, etc. My friends iPhone picks up wifi signals i can't even see. It's pretty annoying. Probably just an inferior antenna inside the phone.
Hi everyone,
My g7 is having problem with wifi (and bluetooth, but I mostly use wifi). The issue is the wifi signal strength is extremely low. Only when I put the phone just next to the wifi AP, it will get a strength of 3-4 (not full) slots. In most cases if you walk away from the AP for about 5 meters, the strength will go down to almost nothing and becomes very unstable.
bluetooth? even in discoverable mode, it is not discoverable.
I think it might be a problem of some kind of antenna inside it. how could I check? i have disassembled it.
I noticed when I remove the chin of it, the phone signal will go to zero (the GSM signal) and I know there is an antenna in it. Isn't the wifi sharing antenna with the mobile network?
My radio is latest according to the forum. Trying cm7.0.3 and oxygen 2.2.1, both same issues.
hardware defect
working fine for me on both and no bug have been reported on both roms.
must be your hardware defect, sorry. still in warranty ?
Hi folks,
I jinxed myself. Yesterday I crowed over successfully replacing my M919 S4 wifi antenna, gaining better wifi performance by about one wifi bar around my house. (The thread is here, if anyone is interested) Basically I just felt my wifi reception was weak enough to suggest a problem, and I wanted better wifi coverage when not right next to a wifi router, so I popped for a few bucks to try a replacement antenna. It seemed to do the trick.
I didn't notice until I left home this morning that swapping the wifi antenna killed my cellular connection. No bars, and "No Service" was listed. Huh. At work, with no tools, I did the usual stuff. Remove/replace SIM, pull battery, no joy. At lunch I went and got a screwdriver. Disassembled / reassembled the unit (took off screws and frame, made sure no bent contacts) etc.. No joy. Went to nearby ATT store for new SIM, no joy.
Came home, and on a lark took out the new wifi antenna and put the old one back in. Rebooted, and all was back to normal. Fine cellular service right away, and back to the previously somewhat weak wifi reception.
I don't understand what could cause this series of events. To be clear, here's the part I used:
http://www.esquareparts.com/product/samsung-galaxy-s4-l720-r970-m919-wifi-antenna-flex-cable/
Is the WIFI antenna also part of the cellular system antenna, and is there a failure/defect mode that would explain why this replacement part would kill cellular service while working fine for WIFI?
I'm very confused. I want to get back to stronger wifi reception, WITHOUT killing my cellular...
Help!
Dude your over thinking it, had a feeling you where chasing a ghost but just waited for you to confirm it. Go to your nearest T-Mobile store and let then do there testing diagnostics and get it directly from the horses mouth. Yes, your phone is defective or no, your crazy. Or find someone with exact phone and compare signals.

I've been known to overthink things. Kind of my calling-card!
But this wifi thing isn't a ghost at all. Any other wifi device I've used in the last several years has had better wifi reception than this particular S4, including an ATT S4 I used for a couple months last year. And it's not just the "reported wifi bars" (which can vary by ROM)... the thing actually frequently disconnects from wifi when I head down to the basement. And in other wifi locations around town, it's reporting much lower. The replacement wifi antenna fixed that and brought it much closer to normal, no more disconnections. Except, of course, for my cellular connection.
If anyone can help explain why the new wifi antenna would completely kill the cell radio functionality (reversibly, thank gosh!), please pipe in. This is a stumper, for me...
And I don't think the T-mo store would do much for me. I'm using the phone on ATT, and I bought it through Swappa, so T-mo doesn't even have me in their system.

hello guys, i need advis,regards with signal dropping and low signal reception of my phone, even i locked with gsm signal
i guess this is not software issue, as i recently reprogram the device, and installed lot of different roms, still the problem do exist,
now im planning to open the device and reconnect the ppossible methods, please anyone here knows where is tthe signal hardware receptor or any signal related hardware so i can try to clean it, and any possible ways or advise to overcome the issue,., dropping signal even the area is quite strong, is so annoying, , thanks guys hope u can help me
currently im using fulmics rom 7.6
Phone looses signal(mostly network) on different areas where there is signal. I read that this could be caused by updates, so I did a fresh install of latest A10 version (it did fix wifi problems), it got better, but still is not acceptable for daily use. Then I installed latest oreo rom, again it got a little bit better, but still not good enough. Afterwards I discovered that if signal has gotten weak setting preferred network type from 4G to 3G or vice versa gets connectivity back instantly. Also for some reason the sim slots are swapped in settings and slot 2 doesn't get signal at all(only saw this when I got oreo, can't say if this was present on A10).
Is this a software or a hardware problem? I got this phone in a pawnshop(had to get a cheap phone ASAP but couldn't afford a new one at the moment) a few days ago and if it has a hardware problem then I still have time to return it, otherwise I would like to fix it and keep it.
Seems like I have found a workaround, I installed latest POSP custom rom and set 4G/3G only in network settings, it still can loose network signal for a few seconds in a low signal area, but a few seconds isn't causing problems. Still have to do some testing but I'm inclined to think that this is a hardware failure, but if my workaround does the job I'm fine with it till I can afford to buy a new phone.
