Connecttion over wifi problems

Hi I have the 2tb mybooklive. Over the ethernet connection I can connect absolutely fine and have no problems, but on wifi through windows 7 and 8CP I can only browse one folder deep, i.e. the public folder after which I get error messages about permissions etc.

I tried on ubuntu last night and had no problems whatsoever, can anyone help get this working on windows???

I have about 700gb’s of stuff on there right now so any kind of factory reset or such isnt an option.

I just read a topic on here I must have missed, and fixed the issue by changing the MTU.

This really shouldn’t be necessary though - luckily im not a stranger to cmd and had no problem diving in and doing this but I expect most average windows users wouldnt…

For those with the same issue and need a guide, try http://www.richard-slater.co.uk/archives/2009/10/23/change-your-mtu-under-vista-or-windows-7/ 

Mark your finding as the accepted answer. Will encourage others to read your solution. 

If anyone has Windows XP then this may also help:
