[Full System Logs Attached below]

 

My System Log is flooded with this message : [dhcps]Lease host name not found. It's happening with all the devices connected to the router. I've also noticed when it happens with an IP, the device with that IP looses internet connection for a short period of time like 30 seconds or sometimes even looses the WiFi signal. My DHCP setting is pretty basic without any modification to the defaults [image attached below]

 

 

Most of the time there's 5 to 6 devices connected. Sometimes there's 1 to 2. I have a computer which is connected via Ethernet. I'm not sure if the computer is effected by this. I've tried factory resetting the router and configuring it from scratch. But to no avail, The problem returned after some time later. I've also tried mailing TP LINK and they are yet to respond. Posted it on their forum and no replies so far.

 

My educated guess is the problem lies within the firmware or might be a bug. The problem is really really problematic when you need a stable connection. Please help me how to solve it if the problem is from my end.

 

 

Thanks in advance

What ISP device is the C24 connected to?

[Thriliya]

I'm not sure about that. But I guess it's a DSL modem as my connection type is PPPoE.

I see you've been posting the same problem on several other forums.

• Is the problem occurring if you set a static LAN IP on the client device? Make sure it's outside of the DHCP pool.
• What if you increase the lease time to 1 day (1440 minutes)?
• Try reverting to a previous firmware prior to the latest if the router allows.
• Set the primary and secondary DNS to Google's (8.8.8.8, 8.8.4.4).

I don't see any 3rd-party compatible firmware from DD-WRT or OpenWRT so there's likely no hope in fixing if it is a firmware problem. The only solution would be to get a new router.

Yes. I am in the hope of finding a solution.

I've yet to try 1,2,3. but I've tried the number 4 before and it didn't work. Thank you. I'll post the update after trying 1-3

Unfortunately I've no other option than to buy a new router or hope the company will fix the bug and release a new firmware.

 

 

Thanks again for the help. I'll post update

Good luck with this one. I wouldn't hold my breath.

 

The Archer C24 is a AC750 class wireless router in TP-Link's budget line. It's unlikely to get fixed with an update. They'll most likely recommend that you buy another router as a "fix".

I've set all the LAN devices to static. And it seems to fix the issue temporarily at least for now.

Will go okay for about 12 hours and then the issue will appear with the respective IP.

Seems like the only option I have.

Their after sale service is the worst
