Thanks John, so I have my SH3 configured in a normal router mode but I have disabled the Wifi SSIDs, and I am using a 3rd party Asus RT AC68U.
I did have it initially configured in modem mode but without over complicating this particular post, it wasnt the best setup for me, mainly due to the way I wanted to allocate IP addresses and also helps me for troubleshooting connectivity issues either from the SH3 or Asus router.
My main home PC I have ethernet connected to the SH3 and all other devices are connected via WiFi to the Asus router.
I have had it setup this way for around 2.5 years and has been fine so far.
RE your earlier post, so I have confirmed from a cabling perspective that all cables are fine, tightened, no breaks in the cables I can see.
I did the full hard reboot at around 15:45 today and can confirm the stats on the router have successfully reset to 0.
I am running my continuous pings to local router, Google DNS and Virign DNS from my main PC and I have not yet seen any failed packets.
I have also not seen any Post RS Errors showing in the stats, and my Network Log has not registered any entries since 12:43 today.
I did call Virgin Support and have to say I got fantastic service from them, so credit where credit is due. They have arranged an engineer to attend on Tuesday but I will see how things go for tonight and tomorrow.
I will follow this post up with the stats from my router as its shows currently.
