why do I have internet connectivity problems?

It sounds like it is the router. I have not seen 1 residential router yet that does not need power cycling to keep it running from time to time.

Sounds like your neighbor got a router and failed to secure it and your crossing networks both set on factory default settings. If you see two routers listed then that means your getting another routers signal. If its just a name and no id its not a secure network and your machines can pick it as a connection. This is the only thing another router seen can mean.

The slow connection is probably due to users from both locations all on one network and/or your running on the wrong router that is far away with a weak signal or you sharing the same channel. Signals can go hundreds of feet right through walls and such and its very common for all kinds of cross connection issues to occur. Have you set each machine to use the one wireless connection only?

First get out the owners guide and secure your router. This will ensure that your neighbors are not signing into your router. You will have to set all the machines to run with the new security settings and set them on your router only so they don't take any other signal. Then you may want to change the channel of the network. I think most come set on 6. Refer to the guide. Ask around to see if a new router is in the area and tell them its not secure. If the problem occurs when the neighbors are home and probably on the computer you found the issue.

I am fairly certain this is it or something like it. Mystery router issues always end up with somebody on a connection they should not be on. Sometime they know and sometime they don't. Sometimes it you sometimes its them or both. If a tech did the install then a tech should come fix it.

You can also enable the router tracking logs and check them to see if somebody is going to websites your family has not used. You can also download free network monitoring tools but your owners guide is the place to start if you want to focus in on who is doing what on your network.

Good luck.

I remember having that problem, it was just the other month acctually. I had to call my internet company and told them the problem, but they said it was either a virus or some messed up plugs/settings. Recheck your plugs (take them out then replug them back in) and try again to reconnect. (Dont forget to reboot) Now, if that doesn't work, try to run a virus scan. If you can't, you have two options. A) -the one I did- I had a CD at the time when I bought the computer. If you run it, it's like a huge memory wiper that makes your computer like it was new with no information at all. After that, I tried to download all other items. This took around two hours. If you can't connect even after that, fear not, it can be your settings. If all else fails, try option B. or B) Take it into a nearby computer store and ask them to do a scan check for you. It'll cost around $20-30 and take maybe a day or two for them to do it (unless they have no other orders to work on). If it is a virus, they'll have to replace your drive and comp with another which is around another $40 or so. You'll also have to reinstall your applications and everything.
