Upload speeds RS700 are slow when compared to etherneted laptop direct to cm3000
Slow upload speeds from rs700+cm3000 2gbit down / 300mb up service plan i am contracted for Comcast tech just left and did a meter-based speed test on the coax line. the coax line tested at 23...
I called into support he had me disable QOS and first try the thing ripped
If Comcast confirms it delivers more than 300mbps for the upload on the cable, the CM3000 + RS700 should be able to get 300mbps upload speeds for the embedded speed test, or at least 150mbps same as the laptop with the USB dongle.
I think we've done this test in our lab. I will check it. Thanks.
Yes I would agree the hardware should support it. 300 is not a huge ask when it's doing the 2k down fine. So yeh the laptop on dingle direct to cable modem sets an atleast minimum to see on the router side of the house. But yeah the techs test meter came back in what we would expect so we know the coax is good so now dealing with firmware or something on the netgear side. I may re do the laptop direct test as well when the isp connection is no longer needed, on a newer nicer laptop with a fresh os image to see if I can even best that first couple of tests directly off the cm3000. Also Comcast certifies the cm3000 at 2.3gps down and 483mbps up
BH_C more testing completed,
took tests from the router its self, as well s the laptop ethernet to router, then did tests with laptop direct to cm3000
from the router admin page
from the speed test page via laptop to router
in both these tests the upload speed aligns, download wont align because the laptop does not have a multi gig port so 1gb exceeds capacity on the down stream
here we can see that the direct to modem had no issues hitting the 355 (plan is only 300 so this over performed)
i do not understand the wall that the rs700 seems to be hitting it can clearly handle the down stream, but its not talking upstream, this feels firmware ish to me. its to late now i need sleep, in the morning i will see if i get different results if i LAG the modem and rs700 together ... like maybe the multi gig port on the cable modem does not have a compatible config with the multi gig internet port on the router
Hi Clonea1,
We just ran the test (RS700 + CM3000) today with our Comcast service (2Gbps DS, 300mbps US), and we could constantly got more than 300mbps for US in our test. We used the router's spped test from the Web GUI.
When you used your laptop to run speed test through the modem directly and through the RS700, did you see if the two tests were against the same Ookla server? The screenshot for the test directly going through the modem does not show which server was used.
Can you try the RS700's speed test vs. some other servers? You can choose different servers from the Web GUI:
From the Advanced tab -> Setup group -> QoS Setup menu: (1) click on the "Select Speedtest Server" button first (2) choose a different server from the slection box on the right. Please see the screenshot below. Please try a few other servers.Besides, when you connected the laptop to the CM3000, did you use the same Ethernet cable that was used to connect the RS700 to the CM3000? Let's make sure the same cable is used.
Thanks.
So i have two cables involved isolated for the testing purposes, i have the cat6 flat black cable that shipped with the rs700 and i have the yellow cat5e STP that shipped with the CM3000. i have tested both cables one at a time direct to the cm300 and got the expected test results on the laptops of the roughly 950* down / 300 up as expected (*i only have a 1gb dongle but this is a test of upstream, down stream as that is happy).
I conducted three sets of tests this took a couple of hours
i pulled all the serverID's from the QOS test page interface and wrote a quick batch file to run speedtest.exe at the CLI so i could export results
I ran the batch file on the laptop under two connections
Direct to CM300
Direct to RS700 via port 4
the router does not have a CLI so i ran each server location manually and transposed to excel
from these results we can see that the direct connect regardless of the serverid gets the expected upstream performance
we can then see that when the rs700 is involved the upstream performance drops regardless of if its on router testing or on laptop testing the results are nearly the same (a suspicious consistent 4mbps tax on the laptop connected to rs700 vs rs700 on appliance test 74 vs 70)
*the router based test doesnt give nearly the details that the CLI test on the laptop gives hence the white spots
*a couple of the test servers seemed to have cripped when hit with a 2gbps load but this is kind of expected and does not changes the findings of the upstream
