Dear knowledgable people who can fix computers,
We are trying to install a wireless router (Voyager 2100)
Yesterday, the router appeared to work but could not connect to the internet. Our ISP thinks the problem maybe with them. However.....
Today, the PC cannot even access the router! *dun dun dun* when we enter the router's IP in IE.
Any suggestions?
The obvious ones are:
a) Is your adaptor working. Check in network conections. If there I would cycle i.e. diable and re-enable it to make sure.

Is the router powered? I would reset it for good measure.
c) Do you have activity lights on the router. If so are they active.
d) Is the phone/cable line connected.
If all the above are ok I would:
a) Do a search for wirless devices. This should list your router if it is not there and the above is all OK i would suspect you have a router problem.

If a is ok and you get a nominal connection I would go to the set up screen for the router (the address for this should be shown in the documentation). This will tell about connection ip addresses etc. If all this is ok and matching the suppliers details you probably have a ISP problem.
c) The remaining possibility is that you have protected the wireless router by putting on a access code(signature) it is possible that the adaptor isnt matching this I forget how to check this maybe YAP will know of the top of his head... (The more I think about it, the more this feels the most likely thing to have happened given you have had it working).
Hope this helps a little,
