I have recently bought a Lenovo IdeaPad Z510. I have a problem after installing Windows 8.1 x64 and all the Lenovo Drivers from Lenovo support site.
My WiFi connection is at 300.0Mbps that is coming from a wireless router TP-link from a Gigabit WAN connection.
Contrarty to my other laptop "Other Brand" which tops at 100MB/upload and download, this Z510 can't get to 100MB and tops at 30MB/upload and download.
Is there a way I can sort this out or this is my wireless card faulty?
A driver from Intel website seems to solve this issue at the moment while Lenovo will check this with engineering team.
A community user suggested the methods below:
how can we improve it?

Nobody doesn't know why but with Windows 8 there is no problems with WiFi and others issues.
Thanks for posting, It is still an unusual issue when it come to win8/win8.1 with wireless. This specific issue is not only limited to Lenovo but it appears to be impacting majority of the Mobile PC industry. From my uderstanding it appears that the Win8 architecture is very different from previous version of the Windows and hence this is making it harder from manufacturers to pin point the root cause. It appears that every time anew driver improvement is rolled out it happens to affect either different parts of the same component or a diffrent components.
We are constantly improving this issue whilst working with the card manufacturers, so i believe it would be just a matter of time before we can stabalise the issue.
