Slow wifi download speeds on Ubuntu 22.04

Question

First things first, I tried to get this problem solved (with no luck) when i was using Ubuntu 20.04, look here Slow wifi ubuntu 20.04 I'm getting only 20Mbps should be getting 300Mbps

So as you can see on 20.04 I was having slow wifi and I tried to get it solved but couldn't, so I thought that hopefully 22.04 would solve the slow wifi issue, that was my hope anyways, but I'm on 22.04 and the wifi is still slow. And it's only the download speeds that are slow, the upload speed is fine. I'm getting about a 30Mbps download speed when it should be about 300Mbps. Oh one more thing, over a wired connection my download speed is about 500Mbps so the wired connection is totally fine, it's my wifi that's got a problem.

Personally I think the wifi driver is bad that's what I think. I'm hoping to get this solved here on askubuntu, if I can't get it solved then I'm going to report this to Canonical as a bug. But hopefully it's not a bug and one of you can help me solve this once and for all.

So what does the link speed mean exactly? Why is it 144Mbps? I thought my wifi router was capable of 300Mbps. Thanks.

Please edit your question to replace all of lspci with lspci -nnk | grep 0280 -A3 and to add the result of: iwlist wlp2s0 freq — chili555, Jan 08 '23 at 14:24

First, I disagree entirely with the advice given at your other question to use channel 8 in the router. Channel 8 is an overlapped channel. Please see: https://www.metageek.com/training/resources/why-channels-1-6-11/ Based on the channel density at your location, I recommend channel 1.

Next, there are some troubleshooting steps that you should consider. Check the settings in the router. WPA2-AES is preferred; not any WPA and WPA2 mixed mode and certainly not TKIP. Second, if your router is capable of N speeds, you may have better connectivity with a channel width of 20 MHz in the 2.4 GHz band instead of automatic 20/40 MHz. I recommend a fixed channel, either 1, 6 or 11, rather than automatic channel selection. Also, be certain the router is not set to use N speeds only; auto B, G and N is preferred. After making these changes, reboot the router.

Please check the antenna connectors to your wireless card. Are both securely snapped into place?

Typically, there is a small door on the bottom of your laptop by which you can see the wireless card.

Finally, the rtl8192ce device is not capable of 5 gHz operation, typically the fastest method. Please see the Full Device Details here: https://device.report/wifi/WFA8643

You could certainly consider a 5 gHz capable USB wireless instead of the internal device.

Hey it says here that it should be able to get 300Mbps down https://www.amazon.com/ASUS-PCE-N15-performance-Wireless-N-interface/dp/B0053GR2YI So I did implement the changes to the wifi that you recommended and it actually made it slower now, now it's only getting about 15Mbps down, what's funny is the down speed is slower than the up speed which is about 20Mbps up. This is so funny. Is there anything else I should try? Should I turn power mode off? Also I made an edit to the post where I have a question so please check that out. Thanks for trying to help. — Cool124, Jan 09 '23 at 05:10
I am thinking about getting a 5 gHZ USB wireless but I'd like to get this thing to work if I can. Do you think the wifi driver might me bad? I am seriously thinking about reporting this as a bug to Canonical. — Cool124, Jan 09 '23 at 05:16
