Am trying to get our wifi signal to reach from the main modem/router into a (farthest) room downstairs. Got a wifi extender and the extended signal in the room in question is too variable; sometimes the transmission rate is great (even over 200 mb) but the next minute it can drop down under 100 or even to 30-40.
So we tried running an ethernet cable from upstairs to the Wifi extender, figuring that would get rid of that part of the problem, but when we then try to hook up to the extended signal, we get an error on the laptop that says something like "Another computer is already using this IP address"... Huh? Anybody know what's going on and how we can remedy the situation?
Thanks in advance,
Jim

I assume that the computer at the extended location has both wired and wirelsss adapters. This would account for the same IP error. The way to resolve it is to open a Command Prompt, or Powershell window and type in the following commands, pressing enter after each:
- ipconfig /release
- ipconfig /renew
- ipconfig /all
The first command releases all assigned IP addresses. The second renews them, hopefully assigning different IPs to the wired and wireless adapters. The third displays all IP addresses in effect. Use it to confirm that there is no IP conflict.
You can use both adapters, or just the wired. If the wireless adapter causes you conflicts, disable it in the Networking section of Settings, or disconnect from it via the Networking icon by the Systray.
The flaky extender signal could be from radio frequency interference. Try using a different Wi-Fi band for the extender. If it was on the 5Ghz band, change to the 2.4Ghz band. It has slower data transfer but broadcasts farther and penetrates walls and floors better. Some extenders connect to two bands at the same time and let you choose which one to connect to on your devices.
Not all extenders are on par. I tried two brands before settling for one that maintains a stead connection. It is a Netgear. The other one was a Linksys. Both have AC prongs on the back to mount directly into a socket on the wall.
