Cawte..
Postavil som si doma menší server s MINI-ITX doskou, kde mám 4 GB RAM + do PCI pripojenú WiFi kartu (ktora dovoluje AP mod):
(blogujem o tom aj tu:
http://buri.sk/02:05.0 Ethernet controller: Atheros Communications Inc. Atheros AR5001X+ Wireless Network Adapter (rev 01)
Subsystem: Wistron NeWeb Corp. CM9 Wireless a/b/g MiniPCI Adapter
Flags: bus master, medium devsel, latency 96, IRQ 20
Memory at febe0000 (32-bit, non-prefetchable) [size=64K]
Capabilities: [44] Power Management version 2
Kernel driver in use: ath_pci
Mám to spravené tak..
V PCI Slot-e, mám Riser kartu ("rozdvojku" pre PCI), kde mám ďalšiu LAN kartu, a WiFi Kartu.
Hlavný LAN port na doske (eth1) slúži ako WAN (internet) a ďalšia LAN karta slúži ako LAN do switchu a WiFi karta ako WiFi AP samozrejme.
Ďalej mám ip forwarding zapnuty, nastaveny cely iptables, spraveny bridge (br0) na eth0 (lan) a ath0 (wifi atheros).
To celé mám ešte cez vlastný dhcp a dns server ktory forwarduje na dns server z wan-u (pokial nema existujucu zonu u seba).
Všetko funguje ako má. Internet ide, cez LAN problem nie je. ping < 1. Vlastne "domeny" cez lan tak isto.. všetko fičí až na jednu vec.
WiFi. Pripojím na WiFi, ping krásny 1-8 ms. ale to iba v "nečinnosti".. ako náhle začnem prenášať údaje, t.j. napr. dam načítať youtube, tak s počiatku tak 1 sekundu načíta čo stihne, a potom.. 50, 100, 2000, 6000ms pingy! a potom sa úplne sekne a kým nedám STOP! v browsery tak zatial wifi už ani nechce odpovedať a až potom sú zasa pingy 1-8ms..
Nejak takto:
Neviete čo s tým? už som skúšal fakt čokolvek.
Driver je v poriadku. Teda vypadá byť v poriadku.. madwifi najnovší. tuším 0.9.4. (ath5k som hodil do blacklistu. na tom sa nedalo spravit wifi ap).

a na koniec ešte nastavenie br0:
root@junior:~# brctl show br0

br0 8000.96a4debb5572 no ath0
a už úplne na koniec ešte nastavenie driveru v modprobe.d/madwifi.conf:
options ath_pci autocreate=none rfkill=0 outdoor=1 countrycode=276
Všetko som nastavoval podla niektorých z routerou čo tu mám. takže hodnoty myslím že OK len
už ma nenapadá čo by to mohlo byť.
Za akúkolvek odpoveď budem vďačný. Vďaka zatial.
