How many signal bars are showing on the WiFi connection?
Are you using the 2.4GHz or 5 GHz channels to connect?
Try downloading, installing and running a free WiFi scanning program to check the WiFi.
Use the program to see the actual signal level that you are using (remember the higher the number in dB the lower the signal strength - it is in -ve values). Also check to see how many other networks are on the same channel. The more networks using the same channel the more chance of interference which can cause problems.
Here is a link to a free WiFi scanner program. It is only one of many available.
Hopefully this will be of some help.
