Has your WiFi always been slow or did this just start happening? Have you tried to connect to another WiFi router to be sure this is not a problem with your connection ? Does your tablet pick up the broadcast of connections within range to your device to connect too and what is the signal strength? When you try to connect to a WiFi connection does your connection get dropped or do you receive any error message? To test it is recommended to try your connection on at least two other routers and see if the results are the same. If so then the problem could be a compatibility issue with your tablet and brand/model number of router, or it could be a problem with your device. If this does not occur on all routers tested this could be a security setting on your router. Also, it has been known to cause problems with your tablet if near lots of other electronic equipment that is turned on. Try your connection away from other active electronics.
