GL-X3000 worse speeds than on TCL HH515L T-Mobile gave me...

Routers

T-Mobile gave me a TCL HH515L for my 5G Home internet. It's an ok device for day to day usage, but for whatever reason i would be disconnected from internet every hour or so while connected to my work vpn. Some games also showed weird behavior, as if disconnecting for a second intermittently.

I got GL-X3000 and these issues are gone, but my download speeds are half of what TCL would get. It would top at 85MB/s, averaging at ~60-70MB/s.

GL-X3000 barely breaks 50MB/s. I haven't made any changes to TCL's setup (it's already barebones in its admin panel) and i don't know what to change in GL's settings. I've already used Band masking to force it to use N78 band, which TCL was connecting to, but GL did that from the get go anyway...

Latency while downloading is also way higher than TCL's...

What can i do?

Hello @sipso to improve the speed, pls try the following suggestion to see if it helps:

  1. Log in to your router and set the cellular TTL to 65 in Cellular Manual Setup.
  2. If using Wi-Fi, switch to 5GHz or try a different Wi-Fi channel
  3. Under NETWORK -> Network Acceleration, enable acceleration mode
  4. Under NETWORK -> DNS, switch to another DNS server like Cloudflare or Google Public DNS

Hello, thank you for the reply.

  1. I already had it set to 65, along with MTU 1420
  2. I’ve tried switching, although Wi-Fi Scanner app shows that my area is not too crowded when it comes to 5ghz
  3. Already had it set to Software. Not sure which is best for my use case scenario so i set it back to Auto. No clue what it does.
  4. This one i actually had set to Automatic so i did change it to Google’s.

I’ll monitor for a while and see if that DNS change helped.

In my experience, TMHI does not require TTL to be changed. I would leave it at default tbh. I would say the same for MTU - there shouldn’t be a reason to change that. My TMHI and my TMo hotspot both come up at 1500.

I changed it as part of troubleshooting, but i didn’t notice any difference so i just left it as that. Setting DNS to Google’s seems to have improved latency while idle.
Although Internet tab still shows the default DNS, i assume this is what the router gets by default from the SIM card?
