Cant see computer on network

[CtChevy427]

Tim and Franko I just want to let you both know I appreciate your time helping me!!!

Since there was some luck with Network Magic installed I felt better but not satisfied with the question of why. So I uninstalled Network Magic from both machines and forced the problem to happen again. With Tim making mention of router settings I remembered I printed out each page and each tab setting per option.
Moving on to today I reinstalled Network Magic on both machines again and now the laptop sees the desk top again. I though lets see what Network Magic changed. I compared my print out, It enabled the "Wireless MAC Filter" and added entries to 3 MAC lines. I copied down all the numbers.
Do you think if I uninstalled Network Magic and then changed this area I will be all set? I'm not looking to save on the cost of the NM because I think it is pretty cool just trying to answer my question of what happened during the firmware upgrade.

If it enabled the wireless mac filters and you see 3 lines....are all three mac address different...I sure hope so as I have never heard of a duplicate number, second thing is if the router is trying to assign the same ip address to different mac addresses....that would indeed cause issues.....
try this....unplug the power from your router, power down on all computers....it seems that you have 3 wireless adapters within range of your router.
Power up the router and power up each device (computer) one at a time and then check the wireless setting to see if there are different UIP address for each computer. You might have a computer set with a static ip and the router doesn't like it.....you should have checked enable "dynamic" ip or something to that affect. You can have static but if you are mobile to other areas you have to tell the computer to assign a IP automatically. This is the preferred method of keeping things simple.

There is a known problem with Vista seeing XP computers and vice versa. Microsoft has a hot fix that got my network running at one time. A router change and now a McAfee upgrade and nothing works anymore. Pissin' me off!

Had similar problems a while back few things to watch for.
Workgroup needs to be the same on both/all computers, this can be found by right clicking on My Computer, must be shareing something, and what realy put it all together was WEP security if you are wireless that is.
ser. key needs to be entered in both computers
WEP can be found by opening internet Explorer and typing 192.168.1.1 which should put you into your router, under wireless tab look for security tab and follow instructions "Right Everything Down" once you are done you are going to have to re-conect to the internet and input your security key (10dig long) never had a proplem again.
let me know how it all works out.
