Everything started out fine. The installer came at the right time, hooked up the cable to the router, plus the phone service so we could get their discount, and the laptop computers easily connected to the new router, with a much faster speed than through the DSL.
Then I asked him to connect my other desktop through the router. It had a wireless card, so I figured it was worth a try. He tried, but since the new network didn't come up, he suggested perhaps my card was not strong enough, and he left.
Not wanting to give up I called Dell yesterday. I did the remote access thing with a very nice technician, but bottom line, he couldn't tell why it didn't work, and he ordered a new card, since my computer was under extended warranty. Someone came out this morning, installed the card, but the network still wouldn't come up, and he was afraid to go further, since he was only supposed to put in the card.
