We have a lot of problem , in B/G mixed mode , no connect to other client , only in B or in G work , but pinging directly the wireless card the time is non accettable ( random 5- to 145 ms .. )
but now we know why … we have our installation on tv-broadcaster tower , we the broadcaster is off , every things work . When go on , not work … interference on motherboard ??
Sure ,the TV station usually uses a high power up to 4KW RF output so the harmonics of this signal may interfer with your signal so you can use 2.4 GHz filter from http://www.hyperlinktech.com.
