Greetings and thanks in advance for any assistance. I have a XPS 420 with a 1505 Draft Wireless Adapter. The best connection I can attain is 54Mbps where my Dell laptop with the Intel Centrino can acheive 130Mbps with no tweeking whatsoever. I have reloaded the driver and monkeyed around with a few of the advance setting to noe avail. This leads me to believe that the 1505 Adapter in my desktop requires some tweeking beyond my limited expertise, but I could be wrong. The modem is an Arris TG-862 G/CT and I have tried finding the set-up to change it's broadcast from b/g/n to n only and apparently I will have to reconfigure the modem to do that. Any suggestions are most welcome and again, thank you.
