Swapped the ethernet cable which made no difference. Statistics -- LAN Interface Received Bytes Pkts Errs Drops LAN1 6,046,280 40,870 3,372 0 LAN3 939,358 8,255 0 0	pctek (84)

Plug yourself into LAN2 for a bit to ensure it's not the port on the router doing something screwy, but basically it's a good time to be looking at your PC or what's between the two...

What do I look for exactly? Swapping ports made no difference. Both PCs are not connected or sharing, they just plug into the same modem. Swapped the ethernet cable on mine, that didn't help....	pctek (84)

If it has to travel vertically try and make the Router higher than the PC so your download speeds will be better. More seriously, while you shouldn't really see errors if everything is otherwise working ok is it really worth worrying about. It's possible there is some source of RF noise somewhere along the cable run that is corrupting the occasional bit of data, difficult to pin down if so. About the only other thing you can consider is the Ethernet hardware in the PC.	dugimodo (138)

Sons isn't, his goes down the floor along, with curls, up through his floor.... I haven't seen an issue, it's just odd I see these and his has none. Maybe I need a long curl round cable too? :-)	pctek (84)
1426591	2016-10-01 18:06:00	If you want to understand the issue then turn on your routers log, give it a level that is high enough to report errors. On your PC, you want to sniff your network, so using a program like Wireshark would help. Reset the statistics for a clean slate. Hopefully, that would be enough to see what error is happening. Errors can occur for a lot of reasons but the most common is packets that fail the crc check. Noise/interference can cause this, so check where your cable runs and avoid power sources that could affect it including light. By the way you said you do bugger all when it appears you have the most activity happening.	Kame (312)
1426592	2016-10-01 18:20:00	Also avoid sharp kinks because the electrons fly out the corners. Ethernet cable really does have a minimum bend radius and bending it too sharply distorts the twist of the wires changing the impedance, adding loss and reducing the noise rejection characteristics. There are all kinds of rules for installers to follow to meet the CAT5/6 etc standard, no cable ties either for the same reason. Your Sons long curling cable is fine, better in fact than tying it in all neatly if you kink it in the process. Also as an aside while the first line was a joke (much like in my previous post), in the case of lightning protection it really does happen. Earth cables for lightning protection need to run in a straight line to the nearest earth point or electrons really will fly out the corners in the event of a lightning strike. Insulation doesn't mean much to a spark that's able to travel between the ground and the clouds :)	dugimodo (138)
