I have a model VPCL236FX. The wifi connection started getting slower off and on about a month ago. Last week it decided to slow to the point I can't open a browser. Looking in settings the connection is still showing good. I also can't get the computer to recognize a USB stick since last week. My laptop and phone have had no problem with connection or speed.
We changed wifi to verizon's FiOS-APKZN about the time the connection started getting slower. But it's hard to blame the wifi since no other devices are having problems. I also "upgraded" to Windows 10 about 6 months ago. After reading some of the posts here I wonder if I need to change the drivers to be compatible with Windows 10 to make the wifi and USB behave. (My laptop is running Windows 7.)
Any insight would be appriciated.
