Hi Everyone,

I've been lurking around here for a while but this is my first post, Great forum and the show is wicked.

I've got 2 wireless networks in my house, one is a shared network for everyone, and the other is a wifi router on my own ADSL line.

I frequently need to hop between the two, is there a way i can be connected to both, so i can access drive shares and printers when i want but still use my faster ADSL for browsing?

I could set one network up on 802.11a and the other on 802.11g i'm thinking this would allow the card to be connected to both. right?

Thanks

Yoof.

yes both networks are addressed identically.

I was wondering if this might work.

802.11a net 192.168.2.x

802.11g net 192.168.1.x

Then i can use the single built in card right? But set my gateway address on the 802.11a radio to 192.168.2.1 and didn't configure a gateway on the 802.11g radio 192.168.1.x. Surely that would mean internet traffic could only go out via 192.168.2.1.

Would that ^^ work?

Thanks

Changing the subnet just allows your computer to use both networks if you could connect it to both. If you left the subnets the same and connected it to both your computer would sit there looking rather embarrassed as it wouldn't know what to do.

You can easily and safely set both networks with a default gateway. You just need to make sure that you only have one default gateway in your computers routing table if you specificity want to use one of the networks to reach the internet.

This still leaves the problem of physically connecting to both networks. Does the driver for your wireless adapter support connecting to multiple networks simultaneously?

I don't know i'll need to check, i've got an intel 3945abg intel card and i'm running Windows 7 RTM.

I'll just go and setup an 802.11a network and see how it behaves if i can get the card to associate to both i mean.

Bad planning ends play, i haven't got a cisco console cable here and i've disabled telnet - Doh!

if you're using 255.255.255.0 for your subnet, these would be two different networks, 255.255.0.0 would work tho.

I don't think its possible to use one card for two connections, best bet would be to use two cards (or your onboard and a express card if you have built in wifi on a laptop,) and dual home the machine. Also, not sure how friendly windows would be with associating with two separate AP's.

Or you could just put everything on the same network... or used a wired network and a wifi network :).
