RTL8192CU based TP-Link WiFi Dongle slow/unstable connection.

[andi4567]

Hi,

as the title already suggests, the driver for the RTL8192CU chipset loads, it connects to the router (with wpa2), but is very slow. A ping response from the router takes more than 20ms on average and should be around 2ms, I suppose.

That's why, HaikuDepot does not receive any packages from the internet. (It would be nice to be informed by the package manager about this btw..)

As far as I can tell the signal strength seems to be very low although it should be pretty high, indeed, because it is not too far away from the router.

After a certain period of time the connection is lost and the device is either reconnected or stays offline. I could not recognize a pattern.

I did not manage to enter the kernel debug land, as I don't have a print key on my laptop's keyboard. Anyhow, I'll provide the other information required according to ​https://www.haiku-os.org/docs/welcome/en/bugreports.html

Kind regards

Your syslog is incomplete/cut off, but the disconnects are logged at least:

KERN: [net/realtekwifi/0] [88:03:55:95:cc:8b] station deauth via MLME (reason: 3 (sending STA is leaving/has left IBSS or ESS))

I don't see any firmware errors or other driver problems, just information from the WiFi stack like this. So I'm not sure what there is to do here.

Does this device work better in Linux?

Ah, there's also this:

KERN: [net/realtekwifi/0] beacon miss, mode STA state RUN

I'm not sure what's going on with all the DHCP requests at the end.

Oh, I'm not familiar with the handling of then haiku-terminal and just used my Linux routines, I'll add the complete syslog tomorrow.

Under Linux the device works quite well with the rtl8xxxu module. The older rtl8192cu module has also been quite unstable, as far as I do remember.

The dhcp requests are probably due to the fact that the connection is being reestablished quite often.

This is the complete syslog of the last boot with the corresponding wifi dongle.

The full syslog just has more of the same errors I noted above, it appears.

I don't think this driver has changed much in FreeBSD lately, so the problem is likely also one in upstream (unless somehow this is a Haiku compatibility issue.)
