T-Mobile 5G Home Internet Gateway slow ethernet but fast WiFi
I recently installed the grey 5G Home Internet gateway at home. When I first got it three weeks ago, I was seeing speeds of 150+ down, and 50 up on both WiFi and ethernet.
Now I am seeing roughly the same speeds over WiFi, but ethernet speeds have dropped to 10-15 down, sometimes as low as 5. Upload is around 15-20.
Has anyone else had this issue and found a solution? Or is the gateway defective? Both ports appear to have the same issue, and WiFi continues to work fine.
I have performed all the steps in that guide and no change. Like I said, WiFi is fast, but wired is slow.
Dude.
I have literally the exact same problem.
I live in the boondocks and only get maybe 10 or so on the wifi but if I plug a PC (I have more than one, and I’ve tried them all) into the ethernet port and run a speedtest I get like…
…wait for it…
...roughly around 150-200 KILObits. Seriously.
Unplug it and use the wifi and I get usually at least a MEGAbit or two.
Whiskey tango foxtrot guys, THIS IS DEFINITELY A BUG, someone get it to the guys that actually do the technical stuff and not the fancy customer service reps please, thanks.
I was fed up with the Cox's pricing so switched. I'm a bit of a geek and power user and planned to just use the gateway as a modem. Connected to the gateway's WiFi I pull ~600Mbps/30Mbps. when I connect directly wired the download drops more than half.~200Mbps, 280Mbps is the max wired speed I have seen.
SOMETHING in the firmware has to be wrong or Nokia used utter crap for the ethernet chipset.
200Mbps is more than enough for anything I need to do at home (yay Colo for the servers) but its annoying that I can't get the full speeds available while running my normal network stack. I would be happy to skip my hardware if the gateway supported VLANS and advanced firewall rules
Having the same issue. 600Mb down through the gateway wifi, 90Mb over ethernet.
Did your wired slower on any devices or just on one of them?
Exact same issue.
Wifi is 660Mbs. using Iphone.
When used a laptop: Wifi = 550Mbps. Lan = 220Mbps. USING SAME LAPTOP!!
tried several laptops and a all in one desktop also (wifi and lan) same.
tested Lan port = 220Mbps. REmoved the lan plug and ran the wifi got full speed 500-600Mbps
Definitely something wrong with the lan ports. Tried both ports. Intent is to add my own router eventually but not if lan is this bad. Lan right now directly connected to the T-Mobile lan port. No devices inbetween.

I have the same issue. All was fine before I went away for the weekend. Came back to find my local router had lost WAN connection to the gateway. Upon restarting the Arcadyan gateway, wired LAN connects at gigabit rate, but actual transfer speeds are very bursty and hence significantly slower. Doesn't matter whether connected via LAN through my external router or with a directly connected PC. When directly using the Arcadyan built in WiFi AP it is fine.
Tried a factory reset, no improvement. My guess is that a firmware update was pushed over the weekend.
Contacted customer support and they are doing an exchange. However overnight the Gateway performed a 2nd factory reset (perhaps the one issued OTA by support) and the LAN speed returned to normal. I'm unsure how and OTA reset would differ from using the hard reset button.
I use to get over 300 mbs on the wired or wi fi, now I'm lucky to get 100 mbs. Hard wired should be faster I would think?
Just got my unit today, same issue (showing firmware ver. 1.00.16)
~200 / 45 Mbps over WiFi direct to gate way
~6 / 5 Mbps direct via any of the two ethernet ports (removed my router from the equation, tried hard resets, Network reset, nada)
For those that got a gateway replacement did that fix the issue?I figured it out, guess reading here put a bias in me that it was somehow the gateway’s issue if WiFi’s fast but Ethernet’s slow… it was my fault lol, if you’re having the same issues perform the following steps before bugging tech support --
- Uso https://www.speedtest.net/ and set the same server for testing, do NOT use Google’s M-Lab that comes up in a blurb when you search speed test (it’s highly inconsistent)
- Run speed test via another browser to see if you get the same results, if you’re getting discrepancies it may be VPN / secure DNS, etc. Make sure your VPN software isn’t running, if on Windows check Internet Options → Connections and make sure there’s no VPNs that’s slowing you down
- Check another device and a third device via Ethernet, if you’re getting discrepancies it’s not the gateway’s problem
- Uninstall your NIC driver and update to the latest, for me it was https://www.realtek.com/en/component/zoo/category/network-interface-controllers-10-100-1000m-gigabit-ethernet-pci-express-software
- Perform a “Network Reset” under System Settings, just type in your search bar
- Worst case if you have a PC that’s still just not performing, buy a new $13 NIC card on Amazon
Now I’m getting 200-400 Mbps on all devices with my old router, a bit inconsistent but beats 4G speeds by a long shot!
