Can't connect wifi with Ralink RT5390 or LAN with Realtek RTL8111

Hardware Support
1

Hello!

I'm using Zorin Core 16.2 - I have this OS on several laptops all running smoothly. I'm a functioning linux user but essentially still a newbie.

I recently bought a secondhand HP Pavilion and installed the same OS but am having trouble with wifi and ethernet.

I have a TP Link mobile internet thing, and a Huawei 5G router, both tested and working.

My HP Pavilion desktop won't find either of them through wifi. When I plug in the ethernet cable to the Huawei, my Settings say "cable unplugged". However, when I connect to the TP Link via USB cable, it works, which is how I'm typing this now.

Here is the output of lshw -C network

Hi, and welcome!

Not sure if this applies to your case but there was a recent thread that you can follow and see if some of the recommendations there help.

Thanks, but I don't think TP Link is the problem here. The computer can't "see" any wireless at all. I have 2 wireless routers sitting next to the computer, a TP Link one and a Huawei one, it can't see either of them.

When I click on "select network" the little circle just spins nand it says "no networks". The laptop (running the same version of Zorin) I have sat next to my desktop computer can see both the Huawei and TP Link routers.

As I say, I'm not hugely knowledgeable, but I suspect the problem is to do with this:

wlp5s0: disconnected
        "Ralink RT5390 1T/1R"
        wifi (rt2800pci), D0:DF:9A:96:8F:B6, hw, mtu 1500
5

That makes two of us... Sorry I misunderstood the issue here, I thought that other thread might have helped.

Just one last guess from my part, can you try to use the connect to a hidden network and enter the details manually? You can find that under Settings -> Wi-Fi on the three dots at the top.

Thank you so much! I will give it a try next chance I get. :+1: :+1: :+1:

I've blacklisted r8169 and installed r8168 but styill no joy with the ethernet. Settings -> network still says "cable unplugged".

I also tried blacklisting rt2800pci, but that has made the wifi menu entry in Settings disappear completely! Output of

lshw -c network

is now:

So my wifi network is now UNCLAIMED, any help on how I can reclaim it? Thank you.

The latest: I removed rt2800pci from the blacklist, which made Wifi reappear in settings. Now, when I boot up, the Huawei router briefly appears as a listed network, then when I try and connect to it, it disappears after a few seconds, and doesn't come back.

I would hugely appreciate any pointers on this as i am entirely stuck!

Is that a Wifi Adapater?

11 
TP-Link M7350

is mentioned in OP. Assume it is this:

12

Then why not just leave the adapter plugged in by the USB in order to access Wifi?

13

Correct @zabadabadoo it's precisely that one.

14

@Aravisian There are various reasons why I would like to fix this, some of which are very mundane and to do with the arrangements of this workstation which I won't bore you with.

One reason however is that I would rather be using the faster 5G Huawei router than the slower 4G TP Link one. However the Huawei one doesn't seem to have the socket to connect by USB, only wifi or ethernet. Although that raises a point: although it isn't working when I connect the Huawei with an ethernet cable directly into the computer, could it make a difference if I used an ethernet -> USB adapter such as this one? https://www.amazon.co.uk/TP-Link-Ethernet-Ultrabook-Chromebook-UE306/dp/B09MFY8799

Thanks for these tips, a few things to try there.

but I'm thinking it's more to do with your router.

To me that doesn't sound likely, because my other router - the TP Link one - also doesn't work through wifi; it only when it is connected through USB - which to me implies the problem is with the computer's wifi hardware setup. As mentioned previously, I the same model of TP Link wifi adapter supplying wifi to 2 laptops both running on Zorin at home (with different hardware of course).

I've never thought of it in hose terms, but it's useful to hear, as it will stop me pursuing this problem down an endless rabbit hole!

Update: I finally have the computer connecting to internet via the Huawei router, by connecting it with Ethernet cable to a USB - Ethernet Adapter. Still no wifi, still haven't resolved getting the thernet cable working directly, but this is certainly a step forward.

@337harvey I still intend to work through your suggestions to get the wifi working (though of course... you know what it's like... once a workaround functions the incentive to fully fix the problem is reduced...) Thanks for your help.
