I have an issue with my new laptop T420s and wifi connections. I cannot connect to hidden networks and in my house its works very slow, and the others computers of my home network works fine. The network adapter of my laptop is Intel 605. I have restored the default settings and doesnt work, and also restored the OS partition. What can I do?
Finally I bought other wireless AP and works perfect!,...but, I don't understand why my others computers worked fine and my laptop no. I think that my laptop network adapter has incompatibilities with some AP, I hope Lenovo or Intel fix this issue.
