Flint 2 Router Connectivity Issues with EE FTTP – Help Needed

Routers
1

Hi all,

I recently purchased the Flint 2 router to replace my EE FTTP hub as I have a 900Mbps connection. Unfortunately, I’ve been struggling with keeping the Flint 2 connected to my broadband service. When it does connect, I’m only getting around 10% of the speed – roughly 90Mbps. However, when I switch back to the EE hub, I get the full 900Mbps without any issues.

I’ve followed the few instructions provided by EE for using third-party routers (EE’s Guide) and have spoken to EE directly. They can’t seem to find any issues on their end, and all appears to be fine with the connection.

One strange thing is, if I keep disconnecting and reconnecting the Flint 2, it eventually manages to connect at 900Mbps, but the process is inconsistent and frustrating.

Has anyone experienced anything similar with the Flint 2, or are there any settings I might be missing that need adjusting to fix the problem? I’d really like to keep the router, as it’s a great device otherwise, but I’m concerned I may have to send it back if this continues.

Any help or advice would be much appreciated!

Thanks in advance!

Quick update:

I’ve also noticed that devices on my LAN ports are auto-negotiating at 100Mbps, which seems off since they should be connecting at 1000Mbps. When I tried forcing the connection speed to 1000Mbps full duplex using ethtool, the devices wouldn’t connect at all. I switched back to auto-negotiate, and they connected at 1000Mbps, but the whole situation feels inconsistent.

I’m starting to wonder if there’s a bug with the router’s hardware or firmware.

Also, I’m still seeing odd results on the WAN port, like: Speed: Unknown! Duplex: Unknown! (255)

Any ideas on what might be causing these issues? Could it be a faulty router, or should I be looking into a potential firmware problem? :frowning: thanks

Does it happen on all Flint2 LAN ports? So on WAN2 as well?

It does yes, I've plugged in varying devices and the ports do the same, which ever Lan port I use. The WAN port also does the same, I had to move to eth1 from eth0 so I could try and manually set the port speed. I have just reset the router to factory. I am not doing anything out the ordinary, just replacing my EE smarthub with the Flint 2. My HP Elite desktop is 1000Mb normally, connect to the Flint and its 100Mb, I tried remove autoneg and it became unknown. I put it back to autoneg enabled and it switched to 1000Mb, plugged in another Lan port back to 100Mb

Could you please try to install the firmware again using the Uboot method? Debrick via Uboot - GL.iNet Router Docs 4

Hmmm did you have any lan connectivity issues ? I was having weird/ spurious connectivity issues with my flint 2 as well

can you try a different model of cable? are the cables you are using atleast within spec for cat5e?

Indeed, I’m using Cat 6 UTP cables, and I’ve also tried Cat 5e to rule out cabling issues. However, since reflashing the firmware (rather than just resetting), the connection has been stable so far. Fingers crossed it stays that way!

I did but the complete reflash seems to make it stable... Wondering whether the update from factory firmware left some kind of residual issue.

Interesting, yea I was having issues with my lan connections through Ethernet , it randomly started working when i restarted the router
