[Q] Disable 5GHz band on stock 4.3 - Xperia SP Q&A, Help & Troubleshooting

Hello guys.
I have no idea about wifi problem on Stock ROM 4.3 .207
My SP always drop wifi connection and there error "Association Rejected"
Already find out the problem and I already try all ways like Auto-Assign IP, unchecked WiFi Optimization etc to resolve that but no luck
I wonder about WiFi certifed but i dont have certified router to check and compare it with my current problem router :laugh:
There one left that i am not try yet. Disable 5GHz band. There some ppl said, disable it (and the 2.4GHz band as default) will be resolved the issue.
So, anyone know how to disable 5GHz band wifi on our SP?? My stock ROM rooted.
Thanks

[Q] Xperia T Wi-Fi problem

I just got an Sony Xperia T,
now I was trying to connect is to my router with the 5ghz-band, but the Xperia T can't find the network,
so then manually added the network, inserterd password, but then it says that the network isn't within reach,
but i'm sitting next to the router, the 2.4ghz-band works fine, and sony confirms that the phone should work with
the 5ghz-band in the white paper of the phone. Does anyone know how to solve this problem?
BTW, my router is a Netgear WNDR3700 Dual Band.

On your router have you set it to dual band as a lot of the time they have it defaulted to 2.4 b/g so you'd need to change it to auto or whatever option allows all. On my Linksys it says 2.4 and 5 as an option in the dropdown. That would be the only reason I can think of. Have you tried with any other device to connect to your 5ghz network?
Likely a router compatibility issue. I can connect to a Linksys e4200 on 5ghz with no problems

My Xperia T refuses to connect to my WiFi AP. It's only 2.4GHz, but according to the logs on the AP, it isn't even trying. On the phone side I very briefly see "Connecting" or similar on the AP list, then it reverts to Saved.
Log on phone is filled with entries like this:
Code:
I/wpa_supplicant( 565): wlan0: Trying to associate with 00:0c:42:XX:XX:XX (SSID='LFWnet' freq=2412 MHz)
I/wpa_supplicant( 565): wlan0: CTRL-EVENT-ASSOC-REJECT bssid=00:0c:42:XX:XX:XX status_code=1
MAC's partially XX'd
This happened on the stock Vodafone ROM, and still occurs on the Generic UK posted in General. I have tried WPA and WPA2, TKIP and AES, different channels, disabling N etc etc, still the same
Tried soft/hard reboots, wipes etc, nothing. It has connected to other public and protected AP's fine.
Am gutted as changing my AP to work around this problem is a no-go. Not had any problems with various other laptops and phones, including other SE/Xperia devices.

I'm on generic UK rom and using a BT Home Hub without any problems. I've also got my old dLink wireless n router I use as a print server and it works fine with that too. My brother has a Sky router (Netgear I think) and that works fine.
I think you must be unlucky.

Is your SSID published? Have you tried turning off all security on the router to see if you can connect then? (obviously I'm not suggesting you leave it unsecured but it is something to try.)
Also, posting your router details may give you an idea if others have been successful with that router before you splash any cash on a new one.
Hi, my Xperia T also is not able to connect with my e4200 5 GHz WiFi. My Laptop and a Samsung Phone works without any problems... I read (sorry I don´t remember the forum link) Sony did not enable the 5 GHz frequency because of driver issues. But if it works on some phones, maybe it´s a provider specific issue like the permanent bootloader lock?
Might be worth updating the firmware of your router?

I think I found the problem, the 5ghz band of my router doesn't have much range appearently, when i'm trying to find the 5ghz band outside of my house, i can't find it, I can only find it when i'm in my room, that's where the router stands, but the 2.4 ghz band has a much better range, I can connect to is almost 20-30 meters outside of my house. I'm wondering when Netgear is coming out with an update for my router, hopefully that will solve the problem, or maybe it will be solved when the Xperia T gets an update to Jelly Bean.

Hi there,
I've just bought the Xperia T and I'm pretty disappointed I can't use my home wifi.
I'm having exactly the same problem - I can see my connection and connect (sometimes) but it is a very poor connection, then after a minute or says "Not in range". If I go outside (which is actually closer to where the modem is) I can get data at an acceptable speed.
Sorry I'm such a noob but can you explain to me where the limitation lies and how I might fix it. Every other device used in the house works - even an old iphone 3gs - I'm surprised Sony's newest phone hasn't implemented technology that must have been in use for years.
Or if it is the modem - any ideas on how to change it.
Sorry - can't give you details - the modem is locked in the landlords garage - so I can't see what make it is.
Thanks for helping a noob.
I have faced the same problem with my TX when connecting to my AP.
I think there is WIFI problem in receiving the WIFI signal of security mode WPA2/WPA.
You can change the WIFI security mode to WEP or No security.
My device can connect the WEP mode WIFI.
Hope you can solve the problem!

Hmmm, that's strange - my modem is set to WEP and it's not really a connection problem but a signal strength problem. But like I said - no other device has this issue. It is hard to test - right now I'm accessing this from a cloud connection which is average compared to another I used this morning, though much better than at home. But I don't know how close I am to the transmitter right now.
Hello again,
I'm still trying to get to the bottom of this:
So my Xperia T can connect and use the wifi in my house fine IF I am within 2-3 metres of my router, which has the following settings -
O2 Wireless Box, model - TG585v7
Software release - 8.2.7.7
Boot loader 1.0.0
Interface Type: 802.11b/g
Band: 2.4G Hz (This unfortunately cannot be changed)
It is currently set to WEP security but when I changed to WPA-2 there was still no change - could only connect when a couple of metres away.
Also even when holding my phone 10cm away from the router I still only get a "Good" connection. So I started to think it must be my phone that is faulty - I've been to coffee shops and picked up the free Cloud wifi ok, though one kept dropping in and out. And I have been into mobile phone shops testing their wifi and it connects.
But yesterday I went to Carphone Warehouse and compared to one of their demo Xperia T phones - the demo was connected to their wifi fine yet my phone could not even "see" their connection - I was sure it was my phone.
But now I'm really confused - today I went to a different Carphone warehouse - there was no demo phone but I picked up their signal and the quality was "Excellent" - something I'd never seen before.
My phone is locked to T-Mobile - can a carrier locked phone somehow restrict access to certain routers?? Seems very weird to me, though I am quite a novice at all of this.
Any help would be much appreciated.
Thanks.
locked phone won't block AP access... maybe backup your data and try master reset.. factory reset... don't need erase sd card.

Are you using the T-Mobile WiFi app? If so delete your connection from settings, then set your home WiFi via the T-Mobile app, it may be connecting to the open one not your full one.
If you don't use the app, I would change the channel on the router and try that.

Wifi 2.4 Ghz to 5 Ghz

Hi friend can i switch wifi band from 2.4 ghz to 5ghz in my xperia z (i have lollipop stock rom android 5.1.1 and i have a locked bootloader allowed no) any solution to do that like a MOD .i dont worry if its neccesery to root my device tnx all
If your Router is sending 5Ghz phone should connect to it, its I remember similar topic in Sony forum, and new software(4.4+) is working with it without changing any setting on phone.
Try setting your router with new AP with only 5GHz, then reset your wifi settings in phone and connect again. Restart both devices and check again.
Or if you have possibility assign new SSID with 5Ghz and remove 2.4Ghz. Some routers(like my Huawei) can send both simultaneously, and I just set secondary SSID for that.
2.4 is crowded like hell almost everywhere but to be honest switching to 5ghz is not big difference for me.
Actually 5GHz have bad signal strength and its have problem with sending it to longer distance. Also if you want use only 5, you should remove every 2.4 AP from your phone, because phone ALWAYS choose stronger signal(and 2.4 is always send stronger signal than 5)

Nokia 8, wifi 5Ghz problem

i have a nokia 8 for a month now . im facing this problem on my wifi that only 2.4Ghz signal is displayed in my wifi list, it seems that wifi is not working properly because there are times that 5Ghz signal are displayed in my wifi list. its like sometimes it works sometimes not and take note that in using the same router with 2.4Ghz and 5Ghz. Also my other phone (Xperia XZ) is working will with both 5Ghz and 2Ghz.
Some routers simply do not work properly with particular phones. I saw such behaviour in the past. Check your Nokia with different router. b
sir i already try on different router, modem ang portable router but i get the same issue.
Try resetting the phone.
i tried it already. reset wifi and data, also factory reset but nothing happened. i already returned to the nokia store. thanks your response sir.
I had the same problem and I think I found the solution,
first of all I tried rebooting and resetting my Nokia 8 and I didn't fix it, updateing the phone did not fix it, returning the phone for a replacement I found that the new phone showed the 5ghz band then an error message appeared and no 5ghz wifi were shown anymore!
the problem is when you set up a new phone you will choose a country, this option will set not only the language but other settings as well among them the channels used by 5ghz wifi in your country! the router might be set to a different country using different channel!
solution: access your router settings and check your wifi 5ghz advanced settings choose a country matching your phone settings and restart your router.
if this didn't work try an android app called wifi analyzer and check channel settings for 5ghz after choosing your country it will show you which channel are open for 5ghz in your country,pick a channel and return to your router 5ghz wlan advanced settings and change the channel option from automatic to your the one from wifi analyzer and apply and restart your router!
hopefully this will work

Mi5 Pro WiFi 2.4GHz issues.

Hello forum members.
I want to share with You My Mi5 Pro WiFi problems, hoping someone can give advice so i can use my Mi5 Pro again.
The phone's WiFi has some issues:
It scan and display all networks, but can't connect to 2.4GHz networks.
It connects and work fine with some 5GHz networks. Also connect and work fine with 5GHz hotspot networks.
Bluetooth is working fine.
MiDrop can scan, but can't connect and transfer.
Hotspot is working only on 5GHz mode. On 2.4GHz can't share or connect to other.*
What I have tried to solve the issues:
Reset the phone.
Update the phone.
Flash other MIUI.
Unlock and flash other Android.
Rooted the phone and changed the WiFi MAC address (on MIUI).
Erased and flashed the modem (NON-HLOS.bin)(on MIUI).
No changes after all my attempts.*
And also, after all My attempts, I have noticed something. When I try to connect to 2.4GHz network (unsuccessful of course) and leave the WiFi on or off (the WiFi is not connected) , the phone's battery is draining very fast. If I connect to 5GHz network (successfully), and after that turn off the WiFi,**the battery is not draining fast.
If someone have any advice, or something I can check or share more info, I'm here and waiting.*
Thanks.
PS:Correction, 5GHz is not working with any router. More specifically, it's not working with most routers.
Maybe it's hardware problem. WIFI antenas disconnected?
Maybe, bit i hope it's software.
When i remove the antennas there is no wi-fi networks even detected, or only the closest ones are shown very weakly.

[I3113] WiFi issues

Hello together,
I have a weird issue with my Xperia 10 (I3113 with unlocked Bootloader on 53.1.A.2.2).
At work we use Cisco ISE Sponsor Portal to provide WiFi guest access. I login using my credentials and everything works fine.
After a while I have to re-authenticate - this happens multiple times per day.
I noticed a similar issue with my WiFi at home. The phone is connected to the WiFi but has no internet access (same phenomenon as at work).
Has somebody experience a similar issue? Is this maybe related to the unlocked bootloader?
Greetings
I had wifi issues before i4193. It disconnects then reconnect itself automatically. I read some thread for xperia phones sine im unable to find any discussion specific for xperia 10. Luckily i found something saying that it underestimate the signals for dual band routers with 2.4 and 5ghz. My router at home is dual band but sharing the same ssid. I have it separated and now problem no longer exist. I can connect either to 2.4 or 5ghz signal without being disconnected. Hope this help.
Thanks for your reply.
I'm gonna try 2.4 GHz only and give feedback
