Re: Wireless + Wired LAN?

Hi Ron

If both networks are separate, that would be fine - unless they are both using the same subnet. In that case, there would be two entries in the laptops routing table for the same subnet, so Windows will load-balance across the two routes, sending some traffic via the wireless and some via the LAN. Clearly that won't work if the device you're talking to is only on one network.

If it's all one big network, ie you have your laptop plugged in to a wireless router, and also setup on the wifi, then you'll likely encounter problems because again both interfaces will be on the same subnet, here at least though it doesn't matter which is used as they both go to the same place.

Stateful protocols - such as SMB - will be broken by this though because the device at the other end expects the whole session to come from a fixed single ip address...

So, in short, unless both networks are separate physically and/or at least separate subnets then only have one enabled at a time.

Cheers

Alex
