So, we got ourselves a TimeCapsule to back up our Mac's (2009 iMac and 2012 Mac Mini), and upon installation, our network went a little haywire.
We've got a Linksys 3200 wireless router serving our wifi, and it seemed to not connect. I found another wifi signal, "Cisco24242," and managed to somehow get rid of it on my machine, but I tried the same thing on the Mini, with no real results.
We can manually log into the wifi from it, but it doesn't hold for very long (a couple of hours) before we need to re-login.
The TimeCapsule is connected with an ethernet connection to both machines (since they're all in the proximity).
umm... AFAIK a TimeCapsule is also a wifi router. So your two wifi devices are probably crapping on each other.
Don't you also have a synology nas? If so, take back that apple turd and use the NAS for backups.
