I got a new laptop today it has poor connection to my wifi and two public BT networks near me as it has about 1/4 or 2/4 all of the time with about a 1.5mb dl speed with my home wifi, whereas all of my other devices, including my old laptop connects perfectly (4/4 bars) with about a 25mb dl speed and it can also reach neighbours wifi networks which my new laptop cannot even see, I was wondering if you could help? I have an ASUS K556UQ, i5 and all of my drivers are up to date,Thanks!
