Hello all!

I have an XPS 15 (an L521). It has always had a slow wireless issue. It is now even worse than before and the system is effectively useless if it is more than 5 feet from the router.

It is not a router or broadband issue as many other devices are working perfectly well. The same happens when the XPS 15 s the only device on the wifi as well, so it isn't loading.

There appear to be many, many entries in the dell support blogs and on blogs outside of Dell relating to slow wireless performance just like this issue. I cannot see a suggested fix/improvement anywhere though and this is now extremely annoying and makes the system unusable.

I have downloaded and installed the latest driver for the Intel 6235 wifi card and that has not made any difference. What can I do to make the system usable again more than 5 feet from the router?

Thank You.
