Xfinity 2gbps/200mbps service and expected speeds

I have a RBK853, and I just upgraded my suburban Chicago service from Xfinity 1200 mbps/60 mbps to 2000 mbps/200 mbps (for a price decrease of $6/month).

 

When I speed test from the RBK850, I get 2348.21 mbps/92.99 mbps, and when I test from my office iMac connected via wifi 6 to a satellite I get about 830 mbps/83.3 mbps.

 

The mesh is using a wifi 6 backhaul with transmission power cut to 50%; are these the speeds I should be expecting?

 

For example, I'm not quite sure about that upload speed from the RBK850; it suspiciously looks like I'm being rated limited to 90 mbps (perhaps due to local loop bandwidth issues), and I'm not quite certain what kind of download speed I should be expecting at the iMac with a wifi 6 backhaul and a wifi 6 connection between my iMac and the satellite sitting 3 feet away.

 

I'm not complaining mind you - but I was expecting (perhaps unreasonably) a bigger jump in my download speed.

 

(Those speeds were all metered at 4:00 AM this morning - speeds are lower during the day when there's real traffic.)

  • Some of that capability will be based on what your devices are designed and supported for. Depending on antenna and MIMO support, 2x2 can only do so much. 4x4 devices should see well over 1Gb.

    Best to check speeds with a wired PC at the ISP modem first to see what's seen there. 

    You'll not see much over 900Mpbs on the Orbi LAN ports due to there limits at 1000Mpbs.

      If you'll look at my speeds from the RBK850, you'll see the Orbi is getting over 2 gbps download. Also note that I'm using a wifi 6 backhaul, and I'm connected to the satellite using wifi 6.

       

      I don't know what the wifi antennas are on my iMac, but do know that the wifi 6 connection to the satellite were faster than a gigabit hardwire connection from my Thunderbolt dock to my satellite's LAN port (which is why my service order prefers wifi 6).


      The 10 gb ethernet port on my iMac goes to a 10 gb private network which includes a Synology DS1821+ with a 10 gb card which gives me access to NAS storage at over 900 MB/sec peak.

       

      Really I'm quite satisfied with my internet speed, but was just curious as to what kind of throughput I could expect with the wifi 6 connection.

        Based on distances of the RBR and RBS, distances between devices and RBR and RBS, and building materials and again, device design and support of it's wifi, will all play a roll in how wifi speeds end up in results. 

  • My Xfinity plan is Download speed: up to 1200 Mbps, Upload speed: up to 200 Mbps

     

    When I test from the Orbi, I get 1400+/- Down, 240+/- up.  So, that's better than advertised! 🙂 

     

    When I test from a wired computer, I get 950+/- Down, 240+/- up.  The switch (Netgear GS316EP) my wired devices go through is only a 1GB switch, so that's about as good as they can do. It's not a fancy switch.

     

    When I tested a WiFi device it varies obviously depending on the device and how far it is from the Orbi.  My iPhone not far from the router gets 500 +/- down, 200 +/- up...except for...

     

    ...sometimes when I run a SpeedTest(c) - this time from iPhone, it can cause the Orbi to reset as it did just now - thrice! (different issue that I have not had time to dig into!) This doesn't happen always, but it's certainly "a thing" I have experienced far too many times.

     

    At any rate, your upload speeds look low - even over WiFi they should be closer to 200.  Why not?
