Model : AC2600 Wireless Dual Band Gigabit Router

Hardware Version : Archer C2600 v1.0

Firmware Version : 1.1.7 Build 20160902 Rel. 33228

ISP : Ziggo

Hello,

I have an issue with this router at this very moment. The router C2600 decided to not broadcast 2.4 GHz anymore. 5 GHz is still broadcasting without any issues.
Currently i have followed these steps using the information found on the internet:

- Upgrade firmware (same firmware)
- Reboot and factory reset
- Unplug cables and replug
- Check logs and stats in which there were two odd things.

The odd things were: When in the "Advanced Status" the Wireless tab shows that 2.4 GHz is broadcasting but it's Channel is at N/A. What it says: Channel: Auto (Current Channel N/A).
Now when i go to "Advanced: Wireless Settings" in the 2.4 GHz tab the "Mode" option is grayed out and the "Channel" option is set permanently on Auto (Cannot change it into any channel at all.)

Screenshots:






I have literally tried all kinds of things and i cannot wrap my head around it other then that it's either a Hardware issue in which 2.4 GHz has failed or something software related.

Any advice is appreciated.

With kind regards,
Sunny Jansen
