Would an Airport Express iron out my gateway's wifi issues if used as a stand-in?

Thanks guys, i'm not even sure if it's possible to turn off the wifi on the router, I will try it when I get home this evening and post the results on this thread later.

So you have an Alice/O2 IAD router (white and grey with a red badge on the top?)

The routers that O2 supply to their customers in Germany are made by a firm called Sphairon.

Hoping you can help; having checked that it is possible to switch off the wireless broadcast on my ISP's gateway device, I have ordered another Airport Express.

I'm wondering what you mean with the following: 'Connection Sharing Off (Bridge Mode)'

Does that mean the Airport Express will not be used in bridge mode?

With the initial set up of the new AE, will it make a difference if I connect it (via ethernet) to my MacBook Pro or to the existing router?

If you could provide a slightly more detailed walk through I would grateful.

I assume you want the new Express to connect to the router?

Correct.

Will there be any settings which I need to enter manually to get the setup working?

So what settings will I need to enter in to bridge mode?

Thanks edex67, does O2 in the UK use PPPoE? This part of the support sheet seems to suggest that i'm going to have problems because O2 here in Germany do.

If you connect to the Internet using PPPoE, you can’t set up the base station or Time Capsule as a bridge. When your device is using PPPoE, it’s acting as a router and distributes IP addresses to clients on the network using DHCP and NAT.

1. Open AirPort Utility, located in the Utilities folder in the Applications folder, select the device you want to set up as a bridge, and then click Edit.
2. Click Network, and then choose Off (Bridge Mode) from the Router Mode pop-up menu.
