Help!!!I can't connect my friend extender

could you describe in more detail what you mean by "can't connect to his extender". Are you referring to a wireless extender?

What is it that you are trying to do?

I'm trying to connect to the internet on my series X and it can't detect my modem. I have an internet range extender and it can't detect it either as long as the main modem is still in running order. If the modem is turned off or not functioning properly I can connect to the range extender, and I get 'Cannot connect to the DCHP server' message. When the modem is turned on, the range extender dissappers from the list and I get a 'Can't connect to wireless network' error. Tired of this, I went to the advanced network' settings, did virtually nothing and when it checked the network' status, I got this error code.

Bear in mind that I've set my console up while it was connected to the extender, this issue wasn't present until one day I tried to start my console up and it just wouldn't connect to the extender or the router. We have a 2nd range extender-ish modem that is connected to the main router, it just works like an extender. And, bizarrely, I can connect to the 'extender modem' with no problems. I have no idea why is that. I have tried the troubleshooting steps (exept connecting via wire bc we don't have one lying around) and it just won't work. I don't want to connect to the 'extender modem' because it's too far away for an optimal connection.

No, I cannot connect direct to the router because it is too far away and there are no other cables in the house where i can plug the router into. When i did have my xbox near my router it connected fine with an open NAT, but i don't want my xbox there thats
why i bought an extender because where i moved my xbox, it can't connect directly to the router as its too far away, thus there being a brick wall to get through. The extenders connection is 3/4 bars if that helps.

There are several things you can try.

BTW, the green flashing light on your extender is normal and a good sign.

One thing you can try is changing the network cable between your Xbox and the Extender.

The next thing I would look at is making sure your network settings for the 360 are set to automatic (DHCP) for both IP Address and DNS. If they are not, set them that way and shut down your 360; then, turn it back on and check for connection to the Internet.

If that doesn't work, I would try to find another device to plug into that network extender. I know you said you don't have another computer, but see if you've got a friend who has a laptop who can come over and plug it into that cable. Make sure your friend
has wifi tuned off. IF your friend can't connect to the Internet, the problem may be with the way your extender is configured.

If possible, connect your 360 directly to the router supplied by your Internet service provider (ISP). Eliminating the wifi extender will tell you if that may be the problem.

I hope this is a helpful start to troubleshooting this.

you sound like you may have a
double NAT issue.

I can't help much sorry as I have my own dramas I can't solve, being a netgear 6110 extender not allowing multiplayer connections, yet a direct connection to the router's wireless can...
