My old DG834GT just didn't have enough power to deliver HD content wirelessly to my HTPC. So I went out and got a DG834N and the WN121T USB adapter. Now it's even worse than before. Speed varies between (claimed) 1mbs and 130mbs. Ping round times vary between 3ms and 1200ms. Get about 1 in 15 lost ping requests. This is doing my head in.
Latest firmware on the router (1.01.06) and latest drivers for the WN121. I've tried dropping max speed on the wireless down to 130mbs max, but doesn't make any difference.
Now what can I try? Placement of the router and the USB adapter seems to make little difference either.
