2 ethernet connection problem.

[sramelyk]

I just bought a d-link 514 wireless router. I already have a 'WIRED' home network using a linksys router/firewall.. I put the d-link on a port off of the linksys router and I can connect to it wirelessly with my IPAQ and can access the internet fine.. My problem.. I have a Buffalo wireless pcmcia card. If I put it into either of my laptops it won't recognize that there is a connection available.. I have downloaded Netstumbler and it I can see my AP, but apparently can't connect.. I am running WEP and have those settings set correctly.. It doesn't even show me that the AP is available.. Now. Keep in mind that I normally am tied to a 'WIRED' network with these laptops, and just on occasion want to disconnect and be wireless.. Can I not do this with two ethernet adapters? Seems like there is some kind of conflict..

And if you disable WEP on the wireless router and the Buffalo PCMCIA card, can it then find the Access Point?

The easiest answer to that is.. NO.. When I first got the wireless router, my first inclination was to try out the wireless card in my laptop without WEP.. I actually connected with one laptop, one time.. I got up and moved to a different room and the connection dropped.. I havne't seen it since... But, like I said, I see it in netstumbler and can connect fine with my IPAQ.. So, I believe my card is functioning properly..

What I am most curious about, is the 2 NIC cards.. This is a viable application right?? When I unplug my ethernet cable, how does my computer know to now use the wireless connection.. Is this a conflict? Do I need to disable the 'Wired' connection?

I do not see the two physical connection problem, you can after all create a wireless bridge to a wired ethernet connection.

Does the Buffalo have a 'Turbo' or double rate mode that is by chance enabled?

No, I don't think so.. What is strange, is that during the crazy restart, turn this connection off, restart, try this, restart, at some point I did connect fine to the router and could access the internet.. i lost the connection and never have gotten it to work again.. I have in the past connected to a few different networks with this card.. I actually got the PCMCIA card first to experiment with wardriving..

What I may do is just reset the router and start over.. I was mainly concerned with a hardware confliction.

I have some issues similar to yours. The only solution I have found that works is to go ahead and remove all WEP functions. Connect to your wireless access point with your Wireless NIC card and establish a good connection. Once that is verifyed, go ahead and configure your WEP. This has worked for me on several occasions.
