Hi. We use a Time Capsule 1 TB as our Wi-Fi connection. We bought it when they were first out. Normally, there are about 3 wireless devices using it: iPod touch, MacBook, MacBook pro. Recently, we upgraded to a wireless printer. So now there are 4 devices competing for connectivity. When we connected the printer, I lost connectivity to my touch. I tried everything, even restoring it (including calling tech support, who had it up and running for a short burst). I'll either get no IP address or an invalid IP address. All was fine before we connected the printer. It seems that no more than 3 devices can connect at once. Is this a limitation of that generation of time capsule? Will an Airport Express remedy the problem?
