Hello ;
My Wireless modem supports channel 1-14 for b/g standards , but when I choose channel 14 on my modem, my SGSII is unable to see the network. I am sure it is working fine because my laptop can connect to my modem and use the internet.
does anyone know any methods to enable channel 14 on SGSII ?
Thanks
Yo, you have two possibilities, either change the channel on your router or flash another modem in your device. I guess the first option is the most hassle-free
It seems channel 14 is only supported in japan, so it would be locked if located anywhere else in the world.
I would imagine this lock is in the wifi firmware but I may be wrong.

Nice insight Veyka, I wanted to try it myself on my ROM however I can't even choose channel 14 for wifi transmission on my router, so yeah...
Thank you for replies , the problem is that I live in a condominium and channels from 1 to 11 are very crowded. so I set the country of my modem to Japan and now it gives me the option to choose channel 14 which is interference free
May be I have to install a radio firmware for Japan ? right ?

Beware using channel 14 outside of japan, there's a reason its not normally there. You may end up causing interference with something critical.
The "radio" file aka the "modem" only effects the cellular radio, not any other radio, you would need to hack around with the wifi modem firmware, aka not an easy "fix".
Flashing a modem wont have ANY effect.
Basically, don't use bands not allowed in your country, the restrictions are there for a reason, and most gear is region "locked" in order to be sold.

Being in the UK I cant pick channel 14 myself Well I could swap my routers region, but yeh, its not cool, the 2.4ghz region is overcrowded anyway without people using channels that are not allowed in there regions

Hello
My Hero (VillainROM 5.2 Release Candidate) won't find my Home Wifi.
All other Wifi he findes without problems.
Did other yours have this problem? Is there a fix!
Seems to be just a problem with 2.1 ROM.
Is there a app for=?
Thanks

Same issue here. Can find 20+ wifi networks in my apartment, but mine is missing.
I suppose this doesn't have nothing to do with developing...Wrong section...Even if I'm not a moderator is pretty annoying to see "there's 1 new topic!" when this is not related with Hero development...
oh i had that issue back when i first got my hero.
Do you have your wifi locked?
Cuz to finally get my hero to find my wifi I had to turn off the security and once it found my wifi i put the security back on and edited the settings on my hero to reflect that.
After multiple flashing of different ROMS i have never had this issue again.
It has something to do with your wifi radio channel.
Try Wifi Analyzer, which will help you map all wifi's around you and help you choose an other radio channel for your router. Scan and choose a channel that's not used.

Thats exactly what i've done. I'm using channel 8, as the only one among the networks i can find using WifiAnalyzer, so im pretty sure that thats not the issue.
why check in the villain thread or ask there or check villain.co.uk

that's very odd, try switching to 1, 6 or 11 then. Choose the one with least AP's on.
Still the same issue i have an apple airport.
First with 1.5 he finds now with the new roms he wants finde my Wifi
Hi,
This might be specific to my provider(Airtel) or city (Bangalore, India) so please excuse me for sending to such a wide audience. But I hope its specific to phone and there is a solution.
I keep loosing my 3g connectivity on this phone. It comes and goes and has now basically become a reliability issue. Most of the times I need to deactivate the data network mode and activate it back.
Has anyone else also noticed this?
It's because where you live 3G service is unstable, same with me also, it goes back to H+.
Regards.
or maybe you should try and change your modem.
try flashing KH1 or KH3, see if it matters..
Thanks for the responses. If its related to network, I guess I don't have a choice. About flashing the ROM, I have not yet rooted the phone and lies is still on KF3, so guess I will wait for the next update and hope things will improve.
I had some similar problems here in The Netherlands... I use a provider that is 'roaming' on another provider's network (for those who are familiar: I use Telfort, which roams on the KPN network).
The current CSC I have in my phone, is a specific CSC for The Netherlands (XENKE1). However, it keeps losing 3G connectivity over time, and I also need to reset the connection to get it back working.
For now I can solve this issue by manually selecting the operator instead of automatic operator selection. You might want to try this, it worked for me at least.
Thanks gscjot. Your solution seems to have worked. In last 20 odd hours I had to manually restart the 3g service only once. So I guess this is actually not a issue with the phone itself but the operator. Thanks a lot.
It might have something to do with the modem or CSC that is in the phone. I am currently on stock 2.3.3 but I tried Darky's rom as well (on 2.3.4). As this ROM has a different CSC, I could leave the network detection on automatic. Only setback then, is that the phone shows 'r' (roaming) on my home network and I have to manually disable 3G when I go abroad.
Best regards,
Gerco

Hi, I have a question regarding receive Wi-Fi connection on my phone. I have an Experia X10 rooted with ThGo2_v13 and non-rooted SG Note, but my experia x10 is unable to detect my home Wi-Fi access point while my SG Note can. So I tried to add Wi-Fi network manually but after added, the xperia x10 still can use it. But both phone can detect some others network nearby us. Anybody know why? Thanks.

Is it an ad-hoc network? If so, then you could try this: https://play.google.com/store/apps/details?id=nl.arendmedia.wifiadhocenabler&hl=en on your X10.
Nope, it's not an ad-hoc network. Does it have anything to do with the custom Rom/kernel?

Some kernels do break wifi functionality. Are you able to connect to other networks? Also, you could try changing the channel on your router to match the one set on your device.
Wifi Channels
Some countries have different wifi channels available, the USA has channels 1-11 and european countries have 1-13 i think. Its possible your hardware is limited to channels 1-11 and your access point is on channel 13, then you wont be able to connect.
Also, some AP's have a "turbo" mode which bumps them up to a 40mhz channel (normal wifi is 20mhz) an ap running at 40mhz wont be able to connect with a client at 20mhz.
I would try locking your AP into channel 6 @ 20mhz if you have the options in your AP.

Yup i can connect to other networks on both phone, but the X10 cant connect to that specific one. Weird!! So, say if i flash some other roms/kernels, can the problem be solve this way?

Wow, i dont know about those channel things that at all..lol. Thanks buddy, i'll try to google for that see if i can find anything.
I understand that there were some changes to android after ICS which adds some difficulty to successfully changing your Wi-Fi Region Encoding (to enable the use of channels 12 and 13), but I was thinking that someone had to have figured out a solution by now.
I have an HTC One S, rooted, S-off, with a SuperCID (11111), and am running a 4.4 Beanstalk ROM port. I recently moved to a new apartment where the wifi situation is very congested (with neighbors using some seriously powerful routers given their signal strength).
Before ICS I was using channel 13 for fun as I had flashed DD-WRT on an old Linksys router. But eventually, because it wasn't necessary, I kept the wifi region on US and just used channel 11.
Though now, because of the congestion in this building, I really would like to go back and use channel 13. Having done so before, it is really frustrating not being able to. My router is set to 13, and I tried changing the region code (there is an option in the ROM) to both Europe and Japan/Russia but channels 12 and 13 are not scanned in either case . I also used sqlite editor and successfully changed the region in Settings Storage (but I hear this is now an obsolete method). In either case, the region is successfully changed but I am never able to scan channel 12 or 13.
I looked at the data on my sim card and it shows an MMC of 310 which I would expect since my cell provider is TMOUS. I read someplace that this is how my available wifi channels are being determined. Can anyone verify this?
More importantly, does anyone know how to configure my phone so I can use channels 12/13? It is really difficult to use wifi even 4 short yards from my router because the signal of -35dbm competes with a router signals on virtually every channel which is similar in strength.
Thanks!

All CM versions >9 have this problem
But it is easy to solve:
In the file \etc\wifi\nvram.txt you can change the line ccode=ALL to ccode=EU.
After a reboot you can use the high channels
If you flash another ROM to have to repeat this.

I've tried a lot of apps but nothing worked!
Changing the nvram.txt worked! Thanks a lot ???
Does this setting only exist on CM? As I have a stock rooted Nexus 9 running android version 5.1.1 and this file does not exist:
\etc\wifi\nvram.txt

Hi there, got myself a TW version X1 iv. Ive found out that it wasn't able to see Wifi 6E (6Ghz) hotspots. I read that TW hasn't adopted Wifi 6E so TW firmware probably has that disabled.
Question: can anyone confirm whether they can see Wifi 6E hotspots on HK / SEA firmware? Can I cross flash other firmwares under the same XQ-CT72 SKU?
Many thanks.
Also: is it something that can be bypassed without having to flash firmware?
Edit: went ahead and flashed HK and then USA firmware, neither worked, still couldn't see Wifi 6E network. Anyone have any luck with this & does the router config matter?

Ct 62 no special config on router my wifi 6e ap is a ubiquity uap 6 enterprise
Hello all,
I was able to figure this out. Here's a copy of my Reddit post:
After importing the Sony Xperia 1 IV "Gaming Edition" from Taiwan to the US for the additional 4GB of RAM (16GB vs 12GB) and ability to unlock the bootloader (the US model, XQ-CT62, does not allow bootloader unlocking), I discovered that my XQ-CT72 would not see my 6GHz network, only my 2.4/5GHz networks. After installing Termux and verifying that 6GHz was indeed disabled (iw list) despite my country code being set to the US already (iw reg get country), I attempted to flash XQ-CT62's modem firmware, which succeeded but still did not enable WiFi 6e. Comparing the firmwares with WinMerge, I found that the Taiwan and USA firmwares have different props set for several RF-related values in /oem/etc/customization/config.prop.
I wrote a short script to override the relevant props on the Taiwan firmware with the props from the US firmware and dropped it in /data/adb/post-fs-data.d (making sure the script was set to executable, i.e. chmod +x) to ensure Magisk would run it before most of Android had been started, and after that was able to see and connect to 6GHz networks successfully:
Code:
#!/system/bin/sh
resetprop -n ro.vendor.sony.wlan.6e_cc_list US
resetprop -n ro.vendor.product.rf.id PDX223-A2US
resetprop -n ro.oem_ant_switch_index_table 0,0,2,0,0,2,2,0,2,2,2,2,2,2,2,2,0,0,2,0,0,2,2,0,2,2,2,2,2,2,2,2,0,0,2,0,0,2,2,0,2,2,2,2,2,2,2,2,0,0,2,0,0,2,2,0,2,2,2,2,2,2,2,2
resetprop -n ro.oem_sar_back_off_index_table 1,2,8,1,6,3,8,1,5,2,8,1,5,2,8,1,1,2,8,1,6,3,8,1,5,2,8,1,5,2,8,1
Note: I tested setting only resetprop -n ro.vendor.sony.wlan.6e_cc_list US without overriding the RF ID with ro.vendor.product.rf.id PDX223-A2US and this did not work unfortunately. ro.oem_ant_switch_index_table and ro.oem_sar_back_off_index_table are probably not strictly required, but since XQ-CT72 (TW) is not FCC-certified, I figured it would be best to adjust the antenna parameters to match the FCC-certified XQ-CT62 (US) just in case.
Reporting back - huge kudos to #8 @noellemercer 's post confirming it is indeed possible to bypass OS lvl restrictions.
I tried out his script but unfortunately still couldn't see WIFI 6E networks. iw reg get returns "unset" countries. In his reddit post he mentioned he was on US mobile network which was infeasible for me ATM, sadly.
I digged further and found out there's another property tied to wifi country code. I made change to that on top of the ones above and voila, all good!
You just need to add one more line to above:
resetprop -n ro.boot.wificountrycode US
Good luck!
Update - welp, I had got ahead of myself...
So after the fix I was able to see & connect to my 6Ghz network. But it remained unusable 99% of the time. My phone might be able to load a webpage or two before the connection would be automatically dropped. Can't even load up the speed test webpage lol!
I guess for me there's more to just setting a flag or two. I tried flashing CT62's modem firmware and it brought no improvements. iw outputs look alright though. @noellemercer how's your speed? Is your 6Ghz hotspot on 160mhz? I am wondering where else I should look at. Maybe all the props?

I'm using an Ubiquiti gateway/router and an ASUS GT-AXE11000 in AP-only mode running asuswrt-merlin 388.1. Channel width is set to 160MHz. I don't have issues with dropouts so I'm not sure what the cause could be unfortunately; I get about 700-900mbps down on speed tests which is about the same as my Pixel 6 Pro (my WAN is 2gbps up/1gbps down).
The only thing I can think of in your case is to check if something is resetting the US country code prop after your network drops, as that's the only client-side (i.e. the phone itself) difference between our setups.
Can confirm that after many tweaks 6Ghz wifi is working reliably. Interestingly webpages do not load as swiftly compared to 5Ghz but disconnects no longer happen. I did have to reconfigure my wireless router, which seemed to be the main culprit. Going forward I'll probably just cross flash USA firmware.
Update 5/12/2023 - can confirm it's still working like a charm after flashing multiple builds. I believe initially the problem lay more with my router (GT-11000AXE). I did a factory reset and format on USB drive, reflashed Merlin and reinstalled scripts that I used, no more drops. The above script is still needed (as Google account etc. might automatically change region) but yes you don't necessarily have to remain on US firmware (I did as I don't plan on using cellular in the near future - even if I do I'll just use basic telephony services).
