Airport express helps

Your English grammar and spelling is a little poor, so its a little difficult to understand what your trying to say

If I'm correct in saying you already have a router which connects directly to your Virgin Broadband Router which then connects into another wireless router... but you are experiencing poor signal from this wireless router, which suggests you must also be experiencing poor wireless signal from your virgin hub?

The question is do you want the Airport express to wirelessly feed of the netgear to boost signal? I would suggest simply replacing the netgear router and replacing it with the airport express as the signal and range is more than likely to be more superior...

In that case also it may be suggested you would enable the router to use DHCP opposed to bridge from the Hub, this means all traffic going through the airport express would be managed by it, opposed to being managed by the Virgin Hub...

 

it only works with airport extreme

 

I read somewhere that the 802.11g model only worked with Airport networks, but the 802.11n version would extend non apple networks. I've tried the first and can confirm it, but I haven't tried the latter, so you may be right.
