Well, I was told the router (3com) would work fine with MacOS. There was no online help for mac installation, but it said for OS's outside of windows, refer to the instructions that come with the router.
Well, my router just arrived, and it has no instructions for Mac or Linux.
I've tried setting it up with limited success...have managed to get into the routers config pages, and have entered settings provided by plusnet, but still no luck in connecting. :/
