[QUOTE="DaFlake, post: 1048548, member: 57419"] OK, let's do a little computer education on DHCP and IP's. When you connect to a network and your computer is set to DHCP (for automatic settings) it sends out a request looking for a DHCP server. If one responds, it asks for an IP and any other associated information for that network like proxy information and DNS. Once it is received, as pointed out, you are "leasing" that IP from the server. The reason for this is that if you remove the computer from the network the server has no way of knowing if that IP is still in use. So, if you removed it and the lease date came due the DHCP server will send a request to the device to "renew" the lease. If there is no response the IP is put back in the pool of valid IP's for the network so that another device can use it later. If you respond the lease is update for another set amount of time etc... Now, if you were to press "renew" all you are doing is send a message to the server that you are still there and still want the IP, that is about it. I use the term server because it is, in fact, a service that is generally provided by a server. However, home routers also include this service to make home networking easier. I suspect that the reasons for your network not reconnecting are due to software. I have heard a few people complain that they kept being dropped from their router on their IPad. You might try a full restore of the device and if that doesn't work you might wait until apple releases the next firmware update to see if they make it a bit more stable. [/QUOTE]
