This is my setup.

Starlink rectangle dish........Starlink wifi router.......Ethernet adapter........PC running Win10 Pro

Issue is slow internet speeds at PC.

I can live with the speeds I am getting but I believe I can do better.

This is the speed test on my PC

When I do the Starlink "advanced" speed test on Samsung S20+ I get this numbers.

Device to Router=67 Mbps up 51 Mbps down

Router to Internet = 244 Mbps up 52 Mbps down

I can understand the "advanced " test on my phone is using the wifi signal and I can live with it.

But the PC test is wired straight from Ethernet Adapter to my PC so I would expect it to be even faster than my wifi.

Any ideas of where to start looking for my missing speed ?

Thanks

Richard

Still on the full plan...going to de-prioritized plan next month.

I just did a restart and I seem to have got back the missing speed on the PC.

Because i am working from home...rural south island for company in Auckland....I hadn't done a restart in a long time.

Will have to see how long it takes before it slows down again.

Thanks

Hi, I would suggest its something wrong at your end, this below is from one of my remote commercial customers, they have several sites and I checked them also, all sites use Starlink via the ethernet adaptor, router in bridge mode to a Mikrotik, which provides Wireguard remote access back to a host in Vultr, this test was taken on a linux box on one of the sites using the CLI test

Hi, check my post above, I did add some further comment, but I never use the supplied router, its always in bypass mode, so that could be an issue, but as your phone is getting decent speeds it sounds more like a bad windows TCP stack setting. Try running a Linux Mint Live CD on your laptop and see what you get.

off topic, but any reason you using wireguard vs mikrotik VPN service?

Just added a mikrotik to my starlink network and looking at ways to access remotely

Boot the windows PC into ubuntu or similar using a live CD.

You say "ethernet adapter" is the RJ45 port not on the motherboard?

I've seen a few faulty Starlink ethernet adaptors, so maybe replace that too.

Thanks for the reply's.

The Ethernet adapter connects the Starlink to my PC...so I have a wired connection not WiFi.

I can prove that the Starlink and the adapter are working ok because if I do a restart on my PC I get back up to

200 Mbps straight away.

It starts dropping from there and over night with just the speed test page and gmail page open it went from 200 Mbps down to

56 Mbps with no one using the internet at all.

I am not comfortable with trying the Linux thing as I live 15 mins from the nearest small town and I need my computer and internet

to be up and running for work.

If I break it I dont even have an internet connection to try and find out what I have broken.

So there is obviously an issue with my Win 10 pro PC but what might it be and how can I test things to narrow the issue dowm

Thanks

Richard
