hi
I wonder if anyone can explain why I suddenly see increased latency when using my main ECI B-Focus V-2Fub/r Rev.B modems?
When I ping websites such as
www.bbc.co.uk and others, it used to return around 9-10ms for many years. Now it is around 18ms since the weekend.
When I use an unlocked HG612 or HH5a (Lantiq chipset) running LEDE 17.01.0, the ping times are back to normal, around 10ms.
I'm connected to a Huawei cabinet. LEDE on HH5a reports System Vendor ID is 'Broadcom 164 140'.
I thought my ECI modem was perhaps faulty, so I tested a brand new 2016 ECI modem with same results, circa 18ms ping times. I prefer to use the ECI because it runs a lot cooler than HG612.
I should add, last week, I was swapping out routers very frequently but I did take care to close the PPP session before unplugging anything.
If DLM has kicked in and applied interleaving, shouldn't I see 18ms ping times regardless of what modem router I use?
Any ideas what's going on?
