No Wifi..is it hardware/software?
I know this has been covered a lot (too much I think, most are unresolved), but I've tired my search skills out, so I'd like to ask for much-needed help. Got an iPhone 3G that used to run on 3.1.3, baseband 5.11. After a few years of no hiccups, this one day my WiFi just decides to give up on me. Turned WiFi off and on again and again but no networks were being detected, not even manually inputted. Rebooted, nothing. Reset network settings, nothing. Reset all, nothing. Restore then jailbreak/unlock (redsnow, offline ultrasnow), still nothing. Did some research. Did the freezer thing, no dice. Found a site that said maybe wifi chip is busted/got fried, but I have a MAC address being shown, and bluetooth works OK. So it can't be a hardware problem, right? Maybe the baseband got corrupted? So I decided to go to 6.15 BB on 4.2.1, never mind I can never go back to lower BBs, and boom! Still no WiFi. Everything works, but not WiFi. Was even trying WiFiFoFum but it still could not detect any when my other wifi phones can! So what could be my issue? Hardware or software? Replace wifi chip? Or something else.
I'd have already pasted/posted my syslog, but man, there's a ton of private data in there. Do we have any rules on proper formatting of syslog posts, removing which lines and showing only which important parts, etc.? Would've searched the forums (wasn't there a sticky bout the syslogs???) if I was thinking straight right now.
3G/EDGE works fine, bluetooth is still fine, GPS is fine, even today on 4.2.
UPDATE: So I cleared my syslog first and turned wifi off and on, ran wififofum, and after letting it run a few cycles, wifi off and on again, then got logs. See http://pastebin.com/7JZpgGcB
