Hi all,

My 300/100 plan with degrees seems to have dropped to 90 mbps download on ethernet seemingly overnight (tested on desktop and laptop to ensure it isnt my port or NIC drivers etc). Previously for about a month it was working swimmingly, as advertised or even exceeding (around 430-500 on Ookla & others).

Wireless is pulling about 130-150 mbps download speed.

I would think maybe it could be the cable? but its a fresh dynamix cat 6 that was added with the fresh wiring a month or so ago. theres no kinks or anything in the cable. Wireless has dropped by about half also...

I have tried resetting the modem (Orbi 6 as per latest $75 2degrees plan) but not the ONT. Only other thing thats hard wired into the router is a hub that monitors the solar power. I live in Christchurch for reference.

There was some kerb work outside the driveway (I live down a lane) on the 16/17th of January and im wondering if possible they mucked it up?

If internal wiring was done by an electrician you need to test it, a cheap continuity tester is good for starters.

If you open "Control Panel\Network and Internet\Network Connections" in Windows, right click on the network adapter and choose "Status", it should tell you the network adapter's connection speed. Additionally, check the lights on the port the cable is plugged into on the Orbi, I believe Amber means 100Mbit, Green means 1000Mbit. At a guess, it sounds like your cable was terminated poorly and is causing noise. I've gone and fixed plenty of electrician installs in my day, they're not generally very good as data techs.

Yep, this sounds suspicously like a cable/termination fault, where the link has dropped down to 100Mbps instead of 1000Mbps due to all eight wires within the cable not having good continuity end-to-end.

For 100Mb connections, only two pairs of wiring within the cable are required, however for gigabit and above, all four are required.

A hacky way of getting two connections over one cable is to use two pairs for each connection. Not recomended, but works in practice as a rough option.

So my edition of the orbi for some reason doesn't show LEDs on the eth ports but I can confirm the link speed is showing as 1.0 Gbps

Do you think it still could be the electricians work even so? thanks for your input
