Try to keep in mind the images above, if you're router is in poor placement for your location, then you may want to physically move it. The router gets internet from the COAX cable, so that means you can move it to any room that has a working TV outlet. you just need a 1-5000mhz splitter and a coax cable to move it and hook it up.
Also it may be something as simple as a setting in your router that you can change that will lessen interference from competing devices
to do that in the router, open a browser, and go to http://192.168.1.1
user name is admin. and the password is most likely the serial number found on the service tag of your VZ router unless you changed it. Once you login succesfully, go to the top and hit wireless, then on the left basic security. then go to option 3 which is channel 1, 6 and 11 and are the only channels you should try.
So it will likely be set to auto, change it to 11 and put the check for keep settings even after reboot (Directly under the channel) and then hit apply. after you hit apply, test your connection out, if you notice a difference, leave it like that until the problem happens again, and if it happens again, go back into the router, and try channel 6, test it out. and then finally 1 if the first two don't work.
If the two above suggestions do not work, then yes you can purchase any WAP from a local retailer or online at a pc shop, or you can buy a wireless N Router to replace yours from Verizon.
