ISP :

I moved into a new house recently and I got a new ISP. My old TP-Link router worked perfectly for the first 2 months, and after that, my internet started dropped every 20 min. I thought my router is broken. So I got a new router and the problem still persists. This is the log:205 May 28 11:33:30 DHCP INFO DHCPS:Send ACK to 192.168.0.100204 May 28 11:33:30 DHCP INFO DHCPS:Recv REQUEST from 68:5D:43:AD:CE:83203 May 28 11:33:26 DHCP INFO DHCPS:Send ACK to 192.168.0.100202 May 28 11:33:26 DHCP INFO DHCPS:Recv REQUEST from 68:5D:43:AD:CE:83201 May 28 11:32:40 DHCP INFO DHCPS:Send ACK to 192.168.0.100200 May 28 11:32:40 DHCP INFO DHCPS:Recv REQUEST from 68:5D:43:AD:CE:83199 May 28 11:32:40 DHCP INFO DHCPS:Send ACK to 192.168.0.105198 May 28 11:32:40 DHCP INFO DHCPS:Recv REQUEST from 7C:67:A2:ED:93:51197 May 28 11:30:30 DHCP INFO DHCPS:Send ACK to 192.168.0.105196 May 28 11:30:30 DHCP INFO DHCPS:Recv REQUEST from 7C:67:A2:ED:93:51195 May 28 11:30:25 DHCP INFO DHCPS:Send ACK to 192.168.0.100194 May 28 11:30:25 DHCP INFO DHCPS:Recv REQUEST from 68:5D:43:AD:CE:83193 May 28 11:30:25 DHCP INFO DHCPS:Send ACK to 192.168.0.105192 May 28 11:30:25 DHCP INFO DHCPS:Recv REQUEST from 7C:67:A2:ED:93:51191 May 28 11:30:23 DHCP INFO DHCPS:Send ACK to 192.168.0.100190 May 28 11:30:23 DHCP INFO DHCPS:Recv REQUEST from 68:5D:43:AD:CE:83189 May 28 11:30:23 DHCP INFO DHCPS:Send ACK to 192.168.0.105188 May 28 11:30:23 DHCP INFO DHCPS:Recv REQUEST from 7C:67:A2:ED:93:51187 May 28 11:29:39 DHCP NOTICE Dynamic IP(DHCP Client) obtained an IP successfully186 May 28 11:29:39 DHCP INFO DHCPC:GET ip:457f72f2 mask:fffff800 gateway:457f7001 dns1:a7ce0db4 dns2:a7ce0db5 static route:0185 May 28 11:29:39 DHCP INFO DHCPC Recv ACK from server a7ce9431 with ip 457f72f2 lease time 21600184 May 28 11:29:38 DHCP INFO DHCPC Send REQUEST to server a7ce9431 with request ip 457f72f2183 May 28 11:29:24 DHCP INFO DHCPS:Send ACK to 192.168.0.105182 May 28 11:29:24 DHCP INFO DHCPS:Recv REQUEST from 7C:67:A2:ED:93:51181 May 28 11:29:20 DHCP INFO DHCPS:Send ACK to 192.168.0.105180 May 28 11:29:20 DHCP INFO DHCPS:Recv REQUEST from 7C:67:A2:ED:93:51179 May 28 11:29:15 DHCP INFO DHCPS:Send ACK to 192.168.0.100178 May 28 11:29:15 DHCP INFO DHCPS:Recv REQUEST from 68:5D:43:AD:CE:83177 May 28 11:29:15 DHCP INFO DHCPS:Send ACK to 192.168.0.105176 May 28 11:29:15 DHCP INFO DHCPS:Recv REQUEST from 7C:67:A2:ED:93:51
