100 is my PC. 111 is my Phone. Both are permanent. 5, 3 and 4 are other devices like Chromebooks and phones, these are not permanent leases..
On my PC when this happens I lose internet and every packet sent trying to ping the local gateway is lost. On my Android device, every time the router does the OFFER/ACK cycle I lose internet connection or the ability to log in at the router, despite the WiFi connection being intact. For Android, the solution is to disable and enable the WiFi function in order to regain access until the next OFFER/ACK cycle. On PC, I have yet to find a solution.
This problem occurred recently for PC, and while thinking it was the QoS being the culprit, I just went ahead and factory reset the router. Everything was fine for a day or so before the issues started showing up again.
This happens regardless if a device has a static local IP or dynamic. I don't understand why the router is running ACK/OFFER on permanent leased IPs, but it does. I don't understand why the host name isn't found either.
It appears this problem gets worse as time goes by, the router more often runs these commands and over the next 3 weeks I expect to have to factory reset again. I've done a lot of digging but every article/forum post pertaining to these symptoms either has no responses or the solution is to install DD-WRT on the router. Now I really like TP-LINK's GUI, much better than that of DD-WRT. But if that's the only way I can get a reliable DHCP server, then I will install it.
I'm hoping someone here has had a similar issue, or knows what causes these symptoms so that I can continue using this GUI.
