TL WR 481 N
I am using an HUAWEI B3310 router on a Vodafone 4g SIM card. I have this connected to 2 tplink routers TL WR 481N
Via a switch and set them up as Access points with smart DHCP the gateway is 192.168.8.1
The router have been assigned 8.1 ip adresses and all is good ...however after a couple of days some some thing is causing the gateway to change adresses last time it was to 9.1 l then had to remove the Ethernet cable to the switch re boot the router (it returned to 8.1 and then re set the tp link routers. any ideas if the routers are causing this or something else
