i have the same problem, and the only way i can access the internet is by connecting to pocket wifi that is connected to dsl router..I have seen other threads about how to resolve this problem but none have worked for me.
I'm not a technician or anything inclined to programming, just pakialamera hehehe, I discovered the resolution that worked for me and thought I would share it.
just follow this easy peasy tutorial
1.right click on wifi signal icon
2.click "open network and sharing center"
3. click "Change adapter settings"
4.right click "wireless network connection"
5. click on "properties"
6. new small window will open where it says NETWORKING at the top....click CONFIGURE
7. click "ADVANCED"
it will show properties that are available for this network adapter
8. click 802.11n Bandwidth and on the right side change the value from "20MHz only" to "20MHz/40MHz auto"
and taaa-daaaa its like a miracle..... i finally have internet access, directly connected to our dsl router!!!!!
