Please can someone help. Have a Netgear D8500, just this last week have been having problems with all desktops losing internet conection via ethernet. Am running windows 10 on 3 new builds. have tried all the obvious. netsh int ip reset
netsh winsock rest
ipconfig/release
ipconfig/renew
ipconfig/flushdns
Nothing works.
Thanking you in advance
 
Very sorry forgot to mention, wifi does not lose connection. The only way i can connect is login via mobile to the router and that starts the lan connection. Thanks again
 
Cat7 best i could buy. Yes PC`s only using ethernet. Will have to check the next on each unit. Yes the DHCP server has a big enough pool. Thank you so much for your reply. My knowledge of networking is limited, Thank you again Regards
 
The D8500 was new on the 2nd February 2017, only had it on for three days when Infinity started playing up. Had to swap back to the dreaded HH6 to deal with BT. Took most of the month to sort it out and get DLM reset. Put the Netgear back Tuesday this week, worked fine until Wednesday. Then these problems started. Googled for eight hours solid went through everything i could. Reset umit to factory settings and started again. Have raised a ticket with netgear, really difficult to deal with netgear direct but, ongoing. You wonderful people as allways are great thank you. I originally thought it was a microsoft problem with dropping connection coming out of S3 but not the case. Because they do not all present exactly the same symptoms. Three units are new builds. My unit is the one i am doing the most work on. Reinstalled windows. I am very frightened not to resrart the connection too many times, as it takes a miracle to get the DLM reset. But prior to this week the HH6 although slower was ok. Thank you again for your kind help. Regards
 
Very sorry people BT have turned up and putting in anew feed so lost internet this via mobile. So wll have to wait for connection thanking you again regards
 
Very sorry just back up this morning, still starting with the little yellow triangle. Getting very sick of that. Tried all suggestions thus far even down to MTU changes and sub nets. The only thing i cannot get is a static IP. On BT Infinity 2. Thanks again Regards
 
restarted PC a dozen times, netsh winsock reset catalog. nets int ip4 reset.log. ipconfig/renew. Restarted 4 times after each. set IP manually as well as Domain name server 81.139.56.100 and 81.139.57.100. re-flashed firmware after resetting to factory settings reset MTU several different numbers after ping tests. then primary DNS as 4.2.2.2 and secondary DNS as 4.2.2.1 rebooted after that. Yes thank ventilation not a problem. Possibly to your last point but when it is working it is flipping great. Thank you for your answers. Regards
