DNS settings

I am having a Xbox Live interconnection problem also, but mine is slightly different because I am working with hybrid technology and a slow internet connection. My Xbox Original, 1st or 2nd edition, from 2000 or early 2001 is upstairs in a spare bedroom/office,
connected via Ethernet into a TP-Link Wi-Fi Powerline Extender (AV500 Powerline Edition) that is plugged into the wall socket; the TP Link Adapter is plugged into the wall socket next to my modem, a Ethernet cable is connected into the TPL Adapter and connected
into my DSL/Modem, which is connected into the DSL/Phone Filter/Jack [CenturyLink configuration]. I run the auto connection and just when I think I am about to connect to XBox Live, I receive the message that I cannot connect. I think I need to push the
modem's WPS button again, press the adapter's Pair button then run upstairs and push the Wi-Fi Clone button on the extender. However, I realize it may not work because the bedroom's wall socket may be on a different circuit than the wall socket downstairs.
I am actually testing the Wi-Fi Powerline capabilities, but I was really hoping I could connect my Xbox to Xbox Live.

I appreciate all laughter be kept to a minimum (ha, ha, ha), but please provide any comments and recommendations you may have to offer.

It stays the same, I've tried that also

Hi,

choose either Cloudflare or google DNS.
They consistently score among the fastest.

I live in ny. Dns numbers now are. 8888. 8844. any better numbers here to put. i feel 2 seconds behind in multiplayer. anythin would help.

Or any other solution

DNS won't help improve latency in real time games that are susceptible to latency.

There are benchmark tools to test DNS resolvers.

Cloudflares DNS servers are quite fast.

8888 8844 is the Google dns: you can try using "automatic" on settings, so you should use the default dns from you telco

Hope it helps!
