Ping delays are very high (100 - 200ms) between two wifi clients connected to the same ath hostap AP, but if I ping the hostap AP itself, the delays are fine (1.7ms - 11b mode). Here is my setup: client 1 ------------ ath hostap AP ------------- client 2 I have tried various configs and combinations, all with the same result: - hostap in 11g mode - hostap in 11b mode - ath clients - wi (lucent) clients - hostap with 5.3-BETA6 , HAL 0.9.6.3 - hostap with 5.3-BETA7 , HAL 0.9.6.3 - hostap with 5.3-BETA4 , HAL 0.9.11.6 , net80211+ath-20040818.patch - Senao 5354 minipci with atheros 5212 - Dlink DWL-AG520 with atheros 5212 - hostap with wi (Intersil - actiontec minipci) - works fine, no problem If I add another subnet (alias) to the ath interface and I route between the clients then it works fine. The problem is only between clients on the same subnet working through an ath hostap AP. Is bridging done inside the HAL ? Are there any one else using an ath hostap AP that can do a ping test between two clients to see if they get the same results. Johann Hugo
