Swapping from XFinity XFi to CM2050V / RAX200 drops my speed tests from 400+ to 100 ish

Hi,

 

I have just swapped today from a XFinity XFi modem/router to a CM2050V / RAX200 combo.  I did tests with several speed apps (inc FCC) and sites and consistently got over 400 Mbps. After the installs I get consistenly around 100. Both were 5g connections off the same PC and Phone in the same locations.  How can this be fixed. I do not have Qos, Parental Control, etc on.

 

Any tips/advise welcome.

 

Thanks in advance Trevor

what speed do you get hardwired into the router? 

what device are you testing on wireless?

are you using the speedtest app on mobile? 

how far from the router are you for testing.  

What firmware are you on? 

Are you using smart connect?

 

I've got a similar setup and can hit 600mbps on an older oneplus 6t with my RAXE500 over the 5ghz. 

Current setup: CM2000-> RBKE963B-> Trendnet TEG-S380-> GS716T-> pi-hole
also in AP setup: RAXE500->EAX80
1.4gig download/50mbps upload from Xfinity

Hi, 

 

Thanks for responding so fast  

 

what speed do you get hardwired into the router? 

   I will test that speed later today as I am working; I have an Xfinity gigabit connection and was testing near that before the swap

what device are you testing on wireless?

   two devices:HP Elite Book i7 Windows 10 and Samsung S20 Ultra 

are you using the speedtest app on mobile? 

   FCC, NightHawk and Xfinity apps,  plus several website inc https://whatismyipaddress.com/speed-test 

how far from the router are you for testing.  

   In office less that 40 feet from router 

What firmware are you on? 

   V1.0.3.106_1.0.58

  Yes

 

Only one other person in house who does stream TV but not present and I am still only getting 200

Make sure to test hardwired into the router and hardwired into the modem. 

to many variables impact wireless speeds so lets start at basics and ensure full speeds at the modem and then at the router.

Thanks, will do,

 

I ma getting a slower speed hardwired also only just above wireless speeds - not what I expected.

 

I checked the pings and tracert and see the response times to the Xfinity gateway and DNS is slow  (see piong and tracert stats below)

 

I will check with Xfinity as this is meant to be a gigabit connection.

I had an Xfinity engineer come out and test the spped which was up to par 800-1100 and using a Cat 6 connection to the Modem has good spped, but unless I am right next to the router I do not get more that 300 at best and mostly 100.  

 

I guest it is just my house - anyhow 100 is good enough as I had move the route into my office and hardwired my office PC for work.

 

Thanks all.
