Wifi Connection can only see 2.4Ghz and not 5GHz

Hello. We recently got fibre optic cables hooked up in our house and I'm trying to connect my PC running bazzite to the new router. It connects fine enough, but only on the 2.4Ghz connection.

I've looked into my router settings and there's no option for me to switch it from there. I'm too far away to have a ethernet cable plugged in as the router is downstairs and I'm upstairs.

Looked in my wifi settings and that hasn't helped me either.

Are the wifi names the same for 2.4 and 5?
jamsaltifyouwill
jamsaltifyouwillOP2mo ago
I assume so yeah. It only gives me one option and it's 2.4Ghz by default If there's supposed to be a second option I'm not sure how I'm supposed to find it
FinnFann
FinnFann2mo ago
Yes if they're the same name it'll go for the most stable connection i.e. 2.4 I don't believe there is a way around that in the gui I haven't configured it outside the gui before. I just run separate names. (Few devices will auto switch outside like phones. Most default to the 2.4. I think windows MIGHT but it depends on how strong the connections are)

Yeah my iPhone connects to 5Ghz just fine Getting 300mbps + on there and like 80mbps on my pc
FinnFann
FinnFann2mo ago
Yeah phones auto switch very reliably. They don't seem to measure the connection difference, just the speed. PCs and KDE's network manager will go for the most stable connection. Which is 2.4 If you can change their names, even if it's just adding to the end, that'd be best. Otherwise I think you have to fiddle with a config file to enforce 5 over 2.4
jamsaltifyouwill
jamsaltifyouwillOP2mo ago
Where can I find the config file? Apologies, I'm still very new to linux.
FinnFann
FinnFann2mo ago
No don't worry. We all were at one point. This is honestly new territory for me as well as I always run them as different names. Only in the last few years have things started to auto switch to the faster speed instead of the most stable. Most devices in my house still will use 2.4 if given the chance aside from my phone.

Aight sick I'll probably just tinker around and see if I can separate it into two connections. I've at least done something like that before anyway lol.
FinnFann
FinnFann2mo ago
Ha if you want to try that first you will have to reconnect devices keep that in mind. Unless you want to keep the 2.4 the same name and just rename the 5 then you'll just need to reconnect anything for the faster. Looking at it there's ways, but I've never used them and of course arch wiki wants to use more obscure tools so... I'm sure someone has an idea. One moment. I threw the question in the main bazzite channel so it gets a little more attention. Usually best to ask there first and then move it to here as well to keep track of things. (Honestly hoping a way is easy because I like being lazy with my connection and separate is a bit annoying) I'd explore more right now but. I'm on the hook for being the meeting presenter at work so I'm off to be miserable handling that XD

run iw list and give us the output, lets see if your 5hgz band is even recognized renaming your networks shouldnt be necessary and isnt good practice either, if your wifi device has 5ghz capability the default is always to connect using that instead of 2.4
FinnFann
FinnFann2mo ago
I'll have to do this myself then since it always defaults to 2.4 even though it'll use 5 if they're separate. I'll try this command myself after my mettings meetings* I'm the guy on the spotlight Alright lemme change my networks around since I can be used as a guineapig. Since I think jam was working on making them separate for awhile.
jamsaltifyouwill
jamsaltifyouwillOP2mo ago
Alright I've ran the command. What specifically do I need to look for?
FinnFann
FinnFann2mo ago
I'll start us off with router on my end for my side GL-MT6000 aka the Flint 2 by GL.iNet Only way to make them both the same name on this is to actually make them the same name, though phones can recognize it as both and choose accordingly. Let me get you my own iw list And just paste the output here! Feel free to censor anything personal
nico
nico2mo ago
its a large output, would be best if you just pasted it in here
nico
nico2mo ago
its just info on your available wifi cards, nothing about networks or anything specific is that the whole output?
jamsaltifyouwill
jamsaltifyouwillOP2mo ago
Yes
nico
nico2mo ago
ok then we've found the issue, you see under "Band 1:" -> "Frequencies:" it lists 2.4ghz frequencies and thats it theres no available band for 5ghz
FinnFann
FinnFann2mo ago
Also we can apparently skip mine. Mine now sees 5ghz. (Software ghosts I'm calling it) Though I do use iwd.
nico
nico2mo ago
so either your wifi card doesnt have 5ghz support, or you need specific drivers to get it working
jamsaltifyouwill
jamsaltifyouwillOP2mo ago
Right ok
FinnFann
FinnFann2mo ago
Would iwd perhaps help them in this situation? I don't know how deep in the stack that operates.
nico
nico2mo ago
iwd is just an alternative to NetworkManager, doesnt change anything about communication with the wifi card
FinnFann
FinnFann2mo ago
Roger Then mine was just being a jerk earlier

jamsaltifyouwillOP2mo ago
I use a tplink reciever. Are there any drivers on linux for that?
nico
nico2mo ago
run lsusb and look for a TPLink device, that way we can find the model name
FinnFann
FinnFann2mo ago
Oh...tplink could have an issue. They've recently started using some stranger chipsets. The micro dongles in particular can be a bit strange. So finding the model is a definite need.
jamsaltifyouwill
jamsaltifyouwillOP2mo ago
It's either: TP-Link TP-Link UB5A Adapter TP-Link TL-WN823N v2/v3 [Realtek RTL8192EU]
FinnFann
FinnFann2mo ago
Sweet that second one even gives us the chipset
nico
nico2mo ago
TP-Link UB5A seems to be a bluetooth adapter so its the other one
jamsaltifyouwill
jamsaltifyouwillOP2mo ago
Yeah thought so I have a bluetooth reciever by them
nico
nico2mo ago
ill look for some drivers
FinnFann
FinnFann2mo ago
Found it already on realtek's website That's a 2.4ghz only adapter. One channel. Supports network type N max
jamsaltifyouwill
jamsaltifyouwillOP2mo ago
Ok nice good to know Problem solved then
nico
nico2mo ago
true good catch, didnt even check the capabilities yep
FinnFann
FinnFann2mo ago
Hey I solved my issue. I kept them separate and would've kept doing so just because my one boot apparently had my network just being a jerk
jamsaltifyouwill
jamsaltifyouwillOP2mo ago
Been meaning to get a proper card anyway. Before I close this, do any of you guys know any decent ones?
FinnFann
FinnFann2mo ago
Hum...I usually use built in...dongles are usually going to be awkward as they rarely give you their actual specs or chipset. There is one to avoid though
nico
nico2mo ago
not sure about that, i always opt to just laying a long lan cable to my room lol
FinnFann
FinnFann2mo ago
Let me get the chipset to avoid since there's one chipset that doesn't have drivers in the kernel yet that TPLink uses ALSO AVOID BROADCOM CHIPSETS AT ALL COSTS. They have been anti linux since 2009 Avoid the RTL8852au or RTL8832AU that some micro tplink adapters use. There are linux drivers, but they aren't in the kernel yet. Only way to get around it is a dkms driver you have to install and I dunno how to do that in bazzite. PCI should do fine, but you never know. If you ever want me to double check feel free to poke in here again or the main bazzite channel. We won't mind helping someone get compatible hardware.

Cheers guys. Yeah I'd preferably go the ethernet route but there's no way to connect my PC upstairs to it downstairs sadly.
FinnFann
FinnFann2mo ago
There is...one way... A way of the ancients A way of obscure standards that are well supported...a way that confuses mortals The Ethernet Over Power standard. BUT that's dependent on your house's wiring Yes there are adapters that let you transmit ethernet between electrical outlets. IT's a weird standard, but it exists and there are a ton of devices. But it depends on your houses wiring and breakers.
jamsaltifyouwill
jamsaltifyouwillOP2mo ago
Yeah I've heard of them before. Pain in the arse to get working properly though from what I have experienced.
FinnFann
FinnFann2mo ago
Worst thing about it is connection drops if someone uses heavy appliances on the same line. And it always works best if the two points are on the same breaker. I just like mentioning it because it's such a strange standard, but I can see it being useful over wifi in buildings that are basically faraday cages (Anything old or stone)
jamsaltifyouwill
jamsaltifyouwillOP2mo ago
I think for now I'm just gonna scour the web for a good card that supports 5ghz and see how that works out lol.
FinnFann
FinnFann2mo ago
If you're in doubt, just look the chipset it uses up and check for linux compatibility out of the box without drivers. If in doubt feel free to ask around here!
jamsaltifyouwill
jamsaltifyouwillOP2mo ago
Will do. Cheers man :)
