Speedtests on Sagemcom using wired ethernet speeds are crippled

I just signed up 5 days ago and got the sagemcom gateway. Noticed I can get 350 Mbps using the sage's wifi but if i do the same speedtest a minute later using wired (ethernet) i get around 40 Mbps.

This makes no sense as wired should always be faster and more reliable than any radio wave signal.

I’m a network engineer and i can transfer 2 files between my 2 computers with the same cables and network adapters at 100 MB/s (1 Gbps) so i'm 100% sure it’s an issue with the gateway

Adding to that, if I repeat  the same file transfer test when connected to wifi, the file transfer is done at 40-50 Mbps as well. I have my tplink mesh connected to one of the ports, so even if i use that signal to do a speed test (which is a wifi 5 mesh, meaning it's capped at 866 Mbps) i get much worse results.

I have seen reported this issue many times over the unofficial tmobile isp reddit specifically when using the sagemcom https://www.reddit.com/r/tmobileisp/comments/ybm7yl/sagecom_to_router_speeds_my_wireless_router_speed/

I recorded a video with speedtests done with wifi and wired and got tforce to create ticket 72045919 . Looking forward to a resolution of this, I'm just hoping it's a bug that can be patched via firmware and not a hardware defect.

    Update: I finally called T-Mobile Internet support.  After I described the fact that WiFi was significantly faster than ethernet with the Sagemcom the agent went away for awhile.  When he returned he said that it was a defective modem and they would issue a warranty replacement.  However, the replacement would be with an Arcadyan KVD21 Gateway (which he said is newer than the Sagemcom).   I'll post an update when I receive and install the Arcadyan KVD21 Gateway. 

     

    the arc is not newer than the sage (not that it matters). all 3 gateway models are buggy and inconsistent. however, i do not believe the arc has the ethernet speed bug

  • Systems engineer here, I am experiencing the same issue on the upload side.  Have the Wavecom antenna installed on SageComm (God send). On Wifi download side is fairly similar almost 400mbps, upload nearly 30mbps, but on Ethernet, its 5 or less.  I think it's time to depart from these junky consumer units. My recommendation is call up Sierra, Cradle Point or PepLink . It will cost you, but issues like this won't exist at least not for long.

     

  • Thanks really appreciate the info. I'm not sure I'm understanding what you did though and why that would solve the issue? 

    Could you elaborate? Thanks!
