[Q] Can't Connect to 2.4Ghz networks

[Leonardo Leal]

Hi Friends,

I've been experiencing some really weird behaviour on my Moto X 1st gen.

My Phone is not Rooted, not flashed... It's all stock running the latest software (Android 4.4.2 Kit Kat) for a while.

Recently I've noticed my Phone stopped connecting to my Wifi Network. It can search for networks and find them, but as soon as I try to connect It to the networks, they become out of range on the list or simply "Saved" and not connected. The Networks WONT connect at all... never ever.

Doing some tests tho, I noticed that my Moto X fails to connect to all 2.4Ghz Networks... It can only connect to 5Ghz ones. I can't figure out why. Tried Clearing Cache Partition, Data Wipe from inside Android and from Bootloader menu... all with no success.

What I come here to ask is: Are there 2 Wifi Radios on the Phone, one of 2,4Ghz frequency and one 5Ghz Frequency? Are there Two antennas and maybe one of them got broken? Do you guys think that re-flashing a Radio Firmware may fix the problem?

Many Wifi Networks run under the 2.4Ghz band. So It is quite important to me to have It working.

I'm asking if I should bother trying because Flashing Radios and Kernels has It's risks, and this phone is my Daily Driver, so I come to you for help or new ideas on how to solve It.

Thanks in advance.

Look in the advanced Wifi settings (three dot menu at lower right when in the network list) and see if the frequency band is set to Auto. If it is set to 5ghz. Putting it on Auto is probably your best bet.

I checked every configuration... I even discovered that the phone doesnt connect specifically to 2.4Ghz networks by switching It first to 2.4Ghz-Only to filter the 5Ghz Networks out and see that no Network connected and then I switched to 5Ghz to check and see that 5Ghz networks do work.

My guess is that Radio Firmware got this strange behaviour after I installed Netgear WiFi Network Analytics App(It started happening after that, afterall)... It might have changed some configuration on the Firmware that I do not have access through the System UI, and is not OS-wise, because not even factory reset worked to fi this... so Only thing that I didnt try yet was a Radio Re-Flash.

Maybe I'll just try It. Or my WiFI Radio just broke.

Hey just replaced my Netgear R6300 with the Netgear R7000 and I am running into the same issue.
My Moto X and my Razr Maxx HD have the same issue seeing the 2.4Ghz, but see the 5Ghz just fine.
All other devices in the household see the 2.4Ghz fine, it just seem's to be the phone's.

Any ideas? I tried two different R7000, and working with Netgear, but no dice.

It's not a biggy, as I have verified it only impact's the phones, and I can set them to 5Ghz anyways.

I was just wondering if anybody has seen this too.

Very odd that it's two different devices. Are you certain that the network is using both bands?

I have the identical problem described in this thread.

Only difference not yet noted is that maybe 1 time out of 50 it will connect to the 2.4ghz network, and stay connected for a few hours. Then it will go back to not working at all for days, weeks.

I've been trying to fix this for months. More than a few people seem to be having the same problem. I've tried every combination of router/phone setting imaginable. Don't think there's an easy fix to this other than new phone or new router.

Update: I've recently been in deep on this problem with Motorola technical support. Several hours on the phone with them, explaining the issue over and over, bug reports, email exchanges, etc etc etc. Tier 4.
At the end of the day, company policy rules and they wont look after me because my phone is outside of the 1 year warranty. I'm still paying for this phone on contract. Not cool. They won't see another dime from me!

Same issue. If I reboot the phone it will connect to a 2.4 ghz network for about 5 minutes... then unable to see the network.
