Oh. Interesting, because I found the MTU setting in the router but it was under the wired settings, not the wireless. If I modify the MTU setting will they affect the performance when the machines are on another network?

The connection works fine when not using the router. Its working fine now with casual browsing, ebay, usually Youtube. Youtube kills it when there's a longer video. |
