I have had a NETGEAR DGND3700 for a few years now with no issues at all.
Also had a 8 port gigabit hub connected to it which has 2 PC's (i7 & AMD FX), TV, phone booster and DVD Recorder etc connected with no problems other than a burt out power supply a year ago.
This is where the problem starts, thought the hub had packed up, so connected the i7 PC direct and all worked ok, so bought a new 8 port hub (Managed)(was late and I was stressed) and had no joy connecting, put it down to needing set up and ordered another 8 port PnP Gigabit hub, plugged it in tonight and still no connections on either PC, take the modem/router cable back to a PC all ok.
I allways rebooted after swapped cables and have tried the M/R cable ingoing to all hubs into each of the 1.2.7.8 ports and not connected at all. Also powered everything down and unplugged things etc.
Have run varius Modem/routers and add on hubs for years. but where am I going wrong with these hubs, Maybe 1 faulty but 2 brand new ones? Also tried alternative lan cables and new ones.
Feeling stupid as it's probably going to be something stupid.
Please also be nice to me as I am no network techie and a lot of it will be too technical for my tender brain.
