Hi guys,
I've been trying to connect my s2 to my 5ghz wifi network but it doesn't seem to connect. I've read some reports that it works on gingerbread, but after ICS, the s2 has problems. I have a feeling now it is a hardware problem but I can't jump to conclusions.
What I've tried so far:
- NeatROM 4.1.2 + Apolo 4.15b
- NeatROM 4.1.2 + Philz stock kernel
- Slimsaber 4.4.4 + DorimanX kernel 10.45 v27
- Slimsaber 4.4.4 + Apolo 7.3
- Slimsaber 4.4.4 + Gustavo kernel
- Allow scanning on AUTO and 5ghz networks
- Change WiFi region code (Tried Australia, United States, Europe and Japan)
What I haven't tried?
- Stock 4.1.2 ROM and stock kernel
- Any AOSP ROM with inbuilt kernel
- Stock Roms before android 4.0.4
Now here are my possible conclusions:
- Dorimanx said that a WiFi driver update since Dorimanx kernel v7 removed 5ghz capability. This was when s4 WiFi drivers were ported, which means all other kernels have the same driver.
- Dead hardware? Unlikely since I take care of my phone and still running strong in 2015.
- Router? Well I bought the new router for a reason and I don't think that it has problems since other devices can connect. WiFi channel is 36 which is non-DFS. Encryption on WPA2-PSK which I'm pretty sure the s2 is more than capable to support it.
Now I found something interesting when using neatrom 4.1.2. Instead of immediately disconnecting, it gives the error message "authentication error" meaning that some went wrong during the connection. However, on 4.4.4 Roms, the phone won't even bother connecting not even giving any error messages.
Let's solve this problem once and for all for all s2 devices since only a handful of people have 5ghz connections whereas a majority don't.
What do you guys experience?
