Flint 2 firmware 4.9.1 some information

Router

Since I don't see any topics about this firmware I wanted to know if it was working well or if it had bugs?

Is wifi coverage still lower than in 4.8.3?

Is there any risk in sticking with version 4.8.3, which works great for me?

updated now to 4.9.1

Please report your idea on this firmware :folded_hands::grin:

This has been covered multiple times in the appropriate 4.9.0 thread. All of the stock firmware from 4.8.4 onwards to date has the ‘correct’ SKU power table values applied for each country, so is operating as intended according to GL.iNet staff. That is NOT going to change going forward.

Sticking on older firmware means your router won’t get other improvements or updates.

V4.9.1 is working fine for me personally.

Yes, looks to be working fine for me as well. Just had to reinstall the additional Luci software like USB printer server and uPnP after the upgrade.

This is the biggest annoyance when upgrading firmware. Kind of wish there was at least a prompt after upgrade that could offer to attempt to auto-reinstall add-ons that were lost in the upgrade, or at least provide you a list of disabled/removed add-ons.

Anyway, fingers crossed, I’ll update here, too.

Well… after updating and reinstalling everything added in LuCI, I can’t connect to the Internet with any of my devices, despite the router showing it’s still able to pull a connection from the ISP modem/router. Very fun… Not sure what I need to do to diagnose this, and would strongly prefer to not have to nuke the Flint 2’s config and start fresh. So far I’ve tried toggling various add-ons to no avail.

Working great for me, even the snapshot build, I didn’t “keep settings” when I updated, I never do and I never have problems when moving to a newer version. You might also try powering down your upstream modem/router to be sure the MAC address is allowed to access the internet. Some isps don’t like when a “new” device connects.

Apologies if I should make my own thread, please let me know.

The only errors I’ve encountered are from trying to reinstall luci-app-upnp which returns the following. Maybe that hints at issues elsewhere…? The router seems to be able to access the net, though.

Yes, I’ve done that already. I suppose I can try it again, for a full 5-10 minutes instead of maybe 2-3.

This has been discussed to death. You need to reveal which country you're in. That will likely be the answer to your question.

US, unfortunately. Not sure what that has to do with firmware updates.

Edit: Whatever, I nuked the setup. Hope I can remember how I had it set up before. :poop:

If you are running NordVPN Wireguard on your router like me with this exact firmware 4.9.1 then you might run into issues.

  1. ​Firmware Profile Caching Bug: When editing or updating NordVPN / NordLynx credentials on the GL.iNet Flint2 firmware 4.9.1, the router's internal uci config database may fail to overwrite the cached .conf file. It keeps reading corrupted/old parameters until you completely purge the VPN profile from the router and re-initialize the NordVPN token from scratch.

  2. My provider is ​Iliad and my Flint 2 is behind my ISP router making it a Double-NAT Overhead (I had to lower it to MTU = 1280): Because Iliad uses MAP-E encapsulation, layering a NordVPN WireGuard tunnel inside my self-hosted double-NAT connection strips off roughly 120+ bytes of maximum packet size. Lowering the MTU all the way down to 1280—the guaranteed minimum payload size for IPv6—prevents large TCP packets from dropping silently when web pages load.
