I've got a weird problem and would appreciate any advice on it. Running WinXP/SP2, if I ping my Linksys (WRT54G-v1) I get 1 or 2ms latency except about 1 ping out of 50 or 60, it's 800ms or even 1500ms. I'm using Hyperwrt 2.1b1 firmware for the router and the regular Linksys drivers for the wireless NIC (wmp54g-v4). I don't think it's the firmware though, this happened using stock Linksys router firmware as well. This doesn't happen wired, only wireless. I've got the linksys firewall enabled, all the 'Block Wan' options selected, wpa-psk with aes turned on (using mac filtering and ssid broadcast disabled too but I wouldn't think that would matter). DHCP is enabled. Again, any advice or similar experience is greatly appreciated.
