Re: Horrible speed and ping on rtl8821ce

Also, the AP phone method is much better than a direct connection, even though the phone is laying right on the laptop.
Would really like for the stupid driver to function properly and me to connect directly.
P.S. Though it's very unreliable.

Re: Horrible speed and ping on rtl8821ce

You'll likely have to suck it up I'm afraid... realtek wifi drivers were always spotty at best, they should™ work better with a bunch of stuff getting upstreamed into the kernel but that's likely only really going to be relevant for newer HW from the looks of it.

Just to be sure, eg. https://bbs.archlinux.org/viewtopic.php?id=278866 was simply down to a hibernating windows - you don't have a parallel OS installed, do you?

Re: Horrible speed and ping on rtl8821ce

I do dualboot with windows, but the "Fast startup" option was completely missing until I enabled it with powercfg /hibernate on, for me to see that it's turned off.

Also, the problem is that the problem occurs at some random interval each time for a random amount of time - rn I'm getting 50-150 ms of ping and 7 mbps.

Re: Horrible speed and ping on rtl8821ce

Does it recover by itself after such episodes?

Indeed, It happens randomly and stops randomly.

Interference (bluetooth) or powersaving.
Can you use a 5GHz AP?

There is absolutely zero bluetooth devices nearby. Also no, the router is a cheap ass one given by the ISP.

Re: Horrible speed and ping on rtl8821ce

Since you're not going to use it, try to rfkill the bluetooth device.
Do you use a wireless keyboard/mouse (a lot of stuff operates on the 2.4GHz frequency but given your phone isn't impressed we're looking for proximity to the NIC res. BT is gonna use the same antenna)

On the subject of dual booting with Windows: my experience: strange issues with a driver in linux were solved with a power off / boot aka cold boot between windows and linux.

Re: Horrible speed and ping on rtl8821ce

What I've noticed, is that like some sort of magic rebooting the router makes the ping stop jumping from 1ms to Alabama every 2-3 seconds.
Reconnected multiple times before trying to reboot, so it isn't a reconnect that caused it.
I do have automatic channel selection enabled, so no idea.
