Mine was doing that to but since started to work...and then last week it wasn't connecting at all for about 4 days and my server wasn't experiencing any problems then it came back and started to connect again, then I start thinking I was going to buy an XRS4900 but will I have these problems if I do ? should I buy a FORMULER Z8 PRO or should I wait and hope the XRS4900 is all good...I'm still up in the air
