I had Lit 1gb fibre to the house installed today, I planned on using my 3 X55 Deco mesh system instead of their router, all went well and I was up and running, now time for a speed test...now to be fair I did not expect 1000mbps, I would have been happy with 500, but between 45 to 50 was definitely a disappointment.

I then installed the Lit router and achieved 1013mbps via the Lit app on the router.  As you can probably tell I am not particularly network savvy and I'm wondering if there is some setting I should adjust on the mesh system?

Thanks in advance
