Windows 7: Cannot access *some* folders on a Network Drive(NAS) via wireless connection

I have recently installed Windows 7 Home Premium on my 2 Desktop PCs at home. They are connected via ethernet to a router. Also connected to the router is a Network Attached Storage device (a Buffalo Linkstation Live). From these PCs I can access files and folders on the shared drive with no problems (for example, I can access the folder \MyNAS\Share\Downloads).

However, on my laptop that connects wirelessly, while I can *see* all the folders on the NAS I can only access a few. For instance, I can see "\MyNAS\Share\Test" (which is an empty folder I created) but if I try to access "\MyNAS\Share\Downloads" it waits for a bit then tells me "\MyNAS\Share\Download is not accessible. You might not have permission to use this network resource. The specified network name is no longer available." Previously the laptop was running XP and I had no problems.

There are no passwords required to access the NAS. I have tried setting the network to both "Home" and "Work". I have tried enabling and disabling HomeGroup. The laptop can access shared folders on the other PCs.

I assume this is something related to wireless security? Please help!

Hi Kaylamarie12,

I had exactly the same issue with windows 7 not connecting wirelessly to my NAS, however there were no issues with a wired connection.

This is the only solution that worked for me (I think it has been suggested by Piptech earlier).

First start an administrator console by entering cmd into the searchbox on the start menu and then do ctrl+shift+enter instead of just enter. In the console enter the following commands to change the MTU:

netsh interface ipv4 show interfaces

Take note of the id number of the wireless interface.

netsh interface ipv4 set subinterface id mtu=1460 store=persistent

This took me months to find, but the answer is:-

============

Take note of the id number of the wireless interface.

netsh interface ipv4 set subinterface id mtu=1460 store=persistent

This worked for me. Apparently it has to do with the wireless router (mine is a Thomson 780WL) not correctly dealing with the default mtu of 1500. There is no need to change the fixed cable interface, that works without problems, it's just the wireless interface that doesn't connect without this modification. More info can be found in this thread towards the bottom  Hope this helps!

Before I bought Win 7 I used Win Xp and had no problem whatsoever to connect to my NAS through the Speedtouch. So, there seems to be something regarding the combination Speedtouch and Win7. But, as I stated before - a new firmware for my Speedtouch fixed it all.

Olly - are you sure you're using the latest firmware for your 716? Sometimes internet service providers keep old "custom made" firmwares just for their convenience. I've seen firmware v6.2.17.5. Is it the one you have?

    Hi Cody,

    Apologiesfor butting in, and this may not be correct forum however the problem this thread appears to be addressing is exactly the same one i have although mine is with Vista Home Edtion please see below for details. I though it might shed some light on the issue to see it may not be Windows 7 specific?

    I have a Dell XPS 420 tower running Vita Ultimate, a Dell XPS M1330 laptop running Vista Home Premium and have recently bought a 2TB WD Worldbook 11 (White Stripe Light) NAS drive configured as RAID 1 (mirrored). It all works swimmingly well with the desktop (wired connection to the router, a Speedtouch 585), however not so with the laptop (wireless).

    I can’t get the laptop to ‘see’ the NAS Drive properly, ie I can’t access the drive’s admin software using either the WD discovery software provided or the IP address of the Drive. The WD software tells me that the drive isn’t there or is not connected properly and internet explorer fails to contact the device’s web page via the IP address. However, I can see the ‘MYBOOKWORLD’ icon in the displayed network connections on the laptop and I can map network drives under windows explorer and I can, apparently, copy files to and certainly see any files that are in folders on the NAS drive. The issue is I can’t access any of the files on the drive from the laptop. As soon as I try to open a file, even one I copied to the drive using the laptop, Windows explorer freezes up.

    I have tried many things – switched off all anti-virus software and firewalls etc, tweaked a registry key to reduce security levels (as suggested by many posts on various forums), connected the laptop with cable to the router and even spoken to WD support (who were not particularly helpful – just said if it’s working on the one machine it can’t be a problem with the drive!), all to no avail.

    Just about at wits end any suggestions gratefully accepted

    Many thanks

    Chris

    Hi Gust+,

    No need to be sorry. Sometimes it's simple stuff that make things work out of the blue. Anyway, it's not an accounts/passwords issue since everything works like a charm over the wired network and via wireless I can't even ping the other computers in the network (ok, I either receive timeouts or actually ping 25% of the packets at most). The only thing that works consistently is the router, all the other stuff just doesn't. Ping works via wired and the alternate USB WiFi stick. The Windows Home Server connector won't talk to the server either.

    Cheers!

    Darren
