My dell laptop keeps connecting and disconnecting from the WiFi. We thought the house was to big so we got an extender that worked for a while. It does this 100+ times a day.

Hi, 

 

Try This:

 

1. Update Wireless driver

2. Try rejoining  your wifi network (delete the saved setting under network and sharing center)

3. Re-seat the wireless card.

 

Good luck.

It's either the signal from the router to the extender is very poor, or distance from extender to your laptop is very poor. The signal strength also depends on the layout of the home and how many walls the signal has to penetrate through. It could be the antenna on the extender has been moved (pet cat playing with it). Those antenna are omnidirectional, meaning the signal is from center out like a circle. Sometimes you have to turn one antenna from being vertical to horizontal so that the beam penetrates the floor better in a upstairs/downstairs scenario. Also everytime a wifi to wifi is used it cuts bandwidth in half. So your ISP may offer 12Mbits download speeds, but using wifi you may see 6Mbit.

 

Best way to hook up an extender is to keep it as near to the router as possible. Before hooking up the extender, Connect the laptop to the router and see when the singals start to drop to get an idea how far you can go. Once the signal starts to drop that is as far as you want to go with the extender. The signals from the router and extender should overlap. Also moving the extender from the wall outlet level to chest level will help a lot. Some of those extenders only have a 3"  antenna buying a 6" or 9" will increase the signal strength. However, that may also be violating FCC antenna regulation.

There may also be the possibility that one of your neighbours may be using an overlapping channel on their wireless network causing interference.
