#Linux 8192cu driver driver

If I disable aggregation in the driver with the attached patch, the problem goes away with a performance loss.ĭiff -git a/drivers/net/wireless/rtlwifi/rtl8192cu/sw.c b/drivers/net/wireless/rtlwifi/rtl8192cu/sw.c The sequence on the air after the deadlock is: The sequence on the air before the deadlock is: That would explain why it only occurs in HT That the aggregation sessions deadlock when a second one starts before I found that the problem only occurs at HT rates.Īfter looking at some more wireshark output, the problem seems to be I have tried different wifi security settings WPA, WPA2, auto cipher, aes cipher and non seem to make a difference. I interested in most flexability for various clients to connect to a stable connection vs best possible wifi speed. If there are specific wireless settings that fix this issue that would be great. Not sure if there is a new driver that can be pulled into the trunk or a patch.īelow is the relevant wifi settings. While researching this issue I've come across other people having problems with the seemingly older rtl8192cu driver. As the ath9k based usb card only allows max of 7. Reason for using this adapter is that it appears from the openwrt wiki documents it should allow up to 25 clients. (Though that same device was able to connect and worked fine when the access point was using the ath9k based usb wifi dongle and same wireless mode and security settings.ģ) a thinkpad client running ubuntu 14 with an open connection to the ap status page also maintains a connection with out issue. Another problem client is a HP office jet wifi printer- same behaviour as the compaq laptop.Ģ) some clients are unable to connect to the rtl8192cu powered access point at all. Running wifi for years on other access points with no issues. The problem client is a compaq running Ubuntu 14 LTS. The problem client is unable to reconnect till the AP is rebooted. Other clients (HP cromebook) stays connected and passes traffic even while the other client is having problems connecting. When they loose connection the wifi on the client appears connected still but not traffic will flow. Hellep please to make it work on kali linux or backtach or xiaopan or beini 1 aziro.

This appears to be an issue in the upstream Realtek driver. Discussion in Wireless Drivers & Utilities started by aziro. Devices that use dual antennas are known not to work well.

There are a few different situations that make the driver not entirely reliable.ġ) some clients don't maintain connections for long periods of time (Suually on less than 15 min). As a rule of thumb, this driver generally works with devices that use the RTL8192CU chipset, and some devices that use the RTL8188CUS, RTL8188CE-VAU and RTL8188RU chipsets too, though it's more hit and miss.
