Corechip SR9900 network

[iKev]

Hello,

I have recently purchased full fibre and I'm having trouble with my drivers.  For some reason my connection is going through Corechip SR9900 USB2.0 to Fast Ethernet Adapter.  I do not have USB 2 on my laptop, only USB 3.  I think this is slowing my connection down.  I have looked at the drivers on the Corechip site but it only shows win11 one and that is it.  I do not have an ethernet port on my laptop so i had to buy an adapter.  Is this causing the issue? It says its a USB 3 but I'm unsure if its true.  I have updated my Realtek drivers just not the wireless ones.  

Any help would be greatly appreciated.

Regards,

Kevin

How did you manage to solve it?

It was a faulty cat 6 cable.  It was only letting 100mbs up and down through.  Fortunately i had a cat 5a cable spare so swapped it out of curiousity and it went back to my realtek drivers and correct speeds.

What driver are you using? In my case it's Coreship SR9900 USB 2.0, since I couldn't find any updates for USB 3.0

Realtek USB GbE family controller is the one im using now.  I think the fault on the cable was making my laptop downgrade to the Corechip SR9900 driver. I read if one wire isnt connected correctly in the RJ45 connector it will downgrade the cable.

If you need internet speeds of under 100Mbps then a cat 5 Ethernet cable is fine.  This will be ok on the Corechip drivers.  If you need faster speeds then you will need to update your cables.  Example: My ISP gives me 1GB up/download.  Then you will need to buy a new Ethernet cable.  You will need a Cat 5 E or a Cat 6 cable. Cat 6 is more popular now. (The design of Cat 6 required more stringent precision in manufacturing, which enabled reduced noise and crosstalk, thereby improving performance.)
