Mobile data speeds on my new router, Puli GL-XE3000 (Spitz GL-X3000 with a battery), are well below what is expected.
I’m in line of sight to one of my carrier’s 4G & 5G masts (LTE, 5G NR SA & NSA).
While my phone achieves 110Mbps download and 60Mbps upload, my router, on the same bands and with the same carrier, only gets 5Mbps download and 2Mbps upload.

This is not a SIM or carrier fault, as the SIM has worked in several other devices with expected speeds, and my carrier confirmed that my data speed isn’t being throttled when in my router.
Using speedtest.net, the download speed will quickly hit 200Mbps, but then start dropping rapidly, down to 5Mbps.
Similarly, speed.cloudflare.com measures 6Mbps download and 2Mbps up, but with the occasional spike to 100+Mbps on download tests.
What I’ve tried:
- TTL changed to 65 (this allows the speedtest to hit 200Mbps before dropping), then 64
- Full reset
- Connected to the router by WiFi and Ethernet
- SIM cards from three providers, with similar results
- Changed APN, as directed by my carrier
- Connected to other masts
- Enabled Band Masking and tried various options
- Changed IMEI (copied from my old iPhone, Pixel, Samsung, Nokia).
- Restarts
I’ve put the SIM in my old Huawei 4G router, which gets speedtest results around 60 down and 30 up. In my old phones the download speed reaches 90Mbps down, and around 40 up.
The router will only connect to LTE and 5G NSA bands, and not 5G SA. I’ve tried forcing it to 5G SA, but it won’t connect and displays ‘SIM not registered’.
The router prefers to connect to LTE band 3 which is 3G/4G, and provides more reliable and faster speed than 5G NSA band n78.
I’ve been trying to solve this for nine hours and I can’t think of what else to do. Suggestions welcome!

This SIM in my Pixel 8 Pro gets 194Mpbs download and 78 upload. In the router, it’s 7 down and 4 up.
Note: This issue persists whether a VPN is connected or not. On the latest factory reset I have not installed a VPN profile, and the LTE & 5G connection speeds have not changed.
