I have a weird wifi problem where my ipad will out of the blue stop talking to my network. I am using a Vigot 2920 router and initially a Zyxel G300H wireless access point using a directional aerial. At first everything was fine then for no apparent reason it stopped connecting, it was not getting a DHCP address from the router, so I put in a fixed Ip address and it connected to the network but not to the internet? now puzzled So I tried another Wireless AP TP-Link AP WA 500g, again it worked fine for a few days then back to the same problem, not getting a DHCP address etc etc. So again I went back to the Zyxel wireless and off it went working fine. I am now suspecting there may be something funny with the router when it comes to renewing an DHCP IP address lease but it just doesn't make sense anyone any ideas?? incidentally everything else I have on wireless connects with no problem even my android phone.
