linksys wireless router - internet connect

[BedRock]

I have a relatively new wrt54G wireless router. It has four pcs connected to it (Call them A, B, C and D) and a cable modem. The pcs have the following characteristics
A: Desktop, Win 2k, wired connection to router.
B: Desktop, Win 2k, wired connection to router.
C: Desktop, Win 2k, wireless connection to router.
D: Laptop, Win XP Pro, wireless connection to router.

All of the pcs seem to connect to the router; all can print on printers attached to other pcs on the network.All pcs are set up the same.. automatic DCHP for example.

Pc's A and B have reliable connections to the internet through the router and the cable modem. They work just fine.

PC's C and D do not. Sometimes C can connect and sometimes it doesn't. Neither one loses the router connection, just the internet one.

I have tried everything I can think of, but I have not yet found the magic bullet. WEP is turned completely off for now. Still doesn't work.

I have tried linksys support - very difficult language barrier and... not fixed.

Anyone out there that can help me?

are you able to ping the router with c and d systems

I'd consider assigning C and D static IP addresses in the 192.168.1.150 to 200 range, use 192.168.1.1 for default gateway, and your ISP's actual DNS. What kind of signal strength are the 2 wireless PC's getting? If it's under 50%, you are going to have issues.

Thanks for the responses. Both pc's b, c, and d can print on printers attached to a. Although I do not know how to ping, nor what addresses to use, it seems i can communicate with other pc's through the router (is that right). Also, signal strength is above 55 for both c and d.

How do i assign static addresses? Why would they help?

You would assign static IP's in the local area connection properties for the wireless cards - TCP/IP, properties, type in the IP address, subnet mask will auto fill in, type in the default gateway and DNS numbers. You can get the DNS from the status page in the router. Connect but no surf is usually a DNS issue, the cards probably aren't getting a proper DNS transfer from the router and if you force it, it will usually work.

ok, here i what i understand so far...

I should set ip addresses as follows:

default gateway: 192.168.1.1
PC "C": 193.168.1.152
PC "D": 192.168.1.153

how do i obtain the ISP's actual DNS, given that it supplies it "automatically". That is how the ISP says to set it.

Also, do I have to do this for PC "A" and "B" as well?

Do I set these IP addresses as "locally administered mac addresses" in the properties of the adapter? Or is this all done in the router?

Needless to say, I am somewhat confused.

You can get the DNS from the status page in the router.

If A and B are working fine, no need, if it ain't broke, don't fix it.

You set the addresses in the connection properties, not the adapter utility. Start, settings, network and dialup connections, local area connection through wireless adapter, right click, properties, TCP/IP, properties.

What addresses do I put there?

While I have been figgering this out, i tried to set up the net with no protection (wep or wpa). That works fine. Steady as a rock. All 4 PCs. Internet, local net, the works.

However, if I turn on WEP protection at the router and try to turn on wep on the two wireless pcs, the win2000 desktop works just fine. However the XP laptop (which gets better signal) links up with the router, but can no longer see the net. I have no idea why that is happening either.

Any ideas?
