Its actually US 2.6 Hardware.

So, I made a classic mistake, upgrading to BE63 to get higher wired network speeds (successful) and then too quickly changing my network provider to get 2000 Mbps internet.

All seemed well at first, but now I'm getting delays when turning on our 3 SamsungTV's (no network found) and drops at various times or slow updating on many other devices. Ookla Speed Test shows 50% reduced intenet speeds and pings of 5-7, DL latency 21.

My house is older with poor Wi-Fi spots, so I have 5 devices, mostly to provide wired internet.  Main TV's no different wired or Wi-Fi source.

I suspect it's my ISP but wanted to check here also, can you have too many devices?

I don't use their router, I take their signal straight to the master BE63, so my next step will be to direct their signal directly to my main PC, which is the standard test from the ISP.

Yes, I have rebooted ISP and Decor units multiple times.

Anything else I should check from your side?

Thanks
