Query: No luck with this one

I tried for hours (and I am quite experienced in technical matters) to get this unit to work with WEP encryption turned on to no avail. I did not call the customer service number because I have no patience with out-sourced technical assistance reading a script, no matter how polite and well meaning they are. Life is too short! Either the gear works like it should or it doesn't. My computers detected the extended network but wouldn't log on to it. All of the equipment in my network is made by d-link and should have been compatible. Returned it to Amazon and received a refund. 5 Stars to Amazon for its smooth handling. Very disappointed with d-link. My next move is to upgrade my entire wifi network with wireless n equipment. I had hoped to avoid that expense.
