this is why I suggest always taping the passkey to the router and the wifi to the bottom of the router. You might try resetting the router to default and go through the configuration again, have you tried first unplugging the router from the power and let it set a few minutes then plugging it back in? that is always the first thing to try. I would shut down the pc, unplug the modem and router, wait a while, plug in modem let it get fully established, plug in router let it get fully established, then boot pc an see if it seems to hold better.

I didn't know what door to knock on and to the best of my knowledge there's no way to triangulate on a WiFi signal using an ordinary computer. Right now there are 12 wireless networks around me, plus my own. I wasn't looking for any personal information but rather something like the name of computers that would point to the owner. For example, if the neighbors are Joe and Sally and the offensively named network has two computers named Joe and Sally... It does illustrate how insecure WEP is though.

OK, so it's a Netgear router. Now we are getting somewhere :-) Open your browser and type in 10.0.0.1 (the router interface) and log in with your admin ID and password. Hopefully you have that information. If it is set at the default the ID is admin and the password is password. It's very insecure if those credentials work. Once the interface loads, you will see a graphic titled 'Guest Network'. It will be on the left sidebar as well as inside the page so just click on it. You need to checkmark the following: Enable guest network Enable SSID broadcast You need to also set the security protocol that the iPad uses. I have standard network devices (no apples) and I use WPA2-PSK [AES]. Enter a passphrase (which becomes the password to connect to the guest network) and hit the big green apply button at the top of the page. You should now be able to see the guest network on the iPad. Select it and type in the password or passphrase and that's all there is to it.

yes if you have wireless in your home through a router which it sounds like you do then you have wifi that is all wifi is a wireless network connection no matter where it happens to be located. 4G is a term associated with cellular networks it is supposed to be the fastest protocol at the moment but it is not available every where so you may ask for 4G and pay for 4G but you may not get 4G you will get what ever band is available in the area you are in and in some areas if there is no coverage by that cellular network then you may not have any connection. you will have to have a cellular data plan to be able to use the 4G ability on the tablet, that will be a monthly fee with some cellular provider. I am not concerned with having that type of connection on my tablets I use mainly wifi connections. I do have a smartphone which does do all the tricks and does have a 4G plan including data so I can use my phone to access the internet where there are wifi networks available free or I can use the cellular data plan and access it through the cell towers if I am in a zone that has coverage. You will pay for that data on the cellular networks if you go over your allowed amount and it can really add up fast. So you just have to decide if you think you will use the 4G connection and if it is worth it to have to purchase a monthly plan to cover usage. I have no idea why it will cost $500 when the google nexus is so much cheaper and is a decent tablet. If it is going to be a 10 inch instead of the 7-8 inch that will be part of it. any cell company has a map you can look at that supposedly shows the coverage areas for the various bands like 4G 3 G etc.
