Random Crashes?

I'm currently working on LDoA for my toon(s) in Pre-Searing and I spend about 30-45 minutes luring Charr. Once I've completed the lure, I kick back and let the Charr level up, afking for the duration of the death-leveling. A couple times throughout almost all of my instances, the Charr cease to move and so do I, followed by a disconnect or even an error. Can I get some feedback as to why that may happen? I run off of a wireless router/laptop with a speed booster and have 3/5 bars of signal almost always. I understand that there may be some interferences in signal-transmissions, but if I sit there and see 3+ signal bars and I'm still getting cut-off, then what other determining factors are there besides that which I've described above? Please help meh... ^^ TY

Could be a firewall or virus scanner blocking something now and then, if you are running Norton or something that would explain it.

Also my wireless laptop/other PC disconnects too at random times, for some reason my WiFi has always been that way.

I'm bad with networking so I can't really help much, I'd just say try playing with the firewall a bit and see if that is blocking the signals.
