Now it's sounding more like a firmware issue on the NAS. I've had this kind of issue with Vista on some of the older firmware NAS units.

[Kruger2002]

Even though I can access everything when its a wired connection?

[JohnWill]

That is really odd, I can't imagine what is happening to make them different.

[Kruger2002]

Have you come across settings anywhere that would restrict access over wireless but trust a wired connection?

Just trying to figure out if its a laptop wireless security problem, router wireless problem or NAS setup problem.....

[Kruger2002]

Just looking at the Buffalo knowledge base again and it states theres a problem with SMB servers and NTLMv2. They're recommending changing "LmCompatibilityLevel" to 2 via "regedit" and if still problems then 1. but advises there are security problems with NTLM...I've never touched regedit so not sure whether to do this or not?

What happens when you try to open one of the folders on the share that you reach via IP?
Do you get an login prompt or what?

Changes that may help to increase the compatibility of Vista with older networking devices:



Disable the IP Helper service:

1. Hold the Windows key and type R, enter "services.msc" (without the quotes) and press Enter
2. Scroll down to the IP Helper service, right click on it and select Properties
3. In the dropdown box that says "Automatic" or "Manual", set it to Disabled and then click on "Apply"
4. Then click on "Stop" to stop the service from running in the current session
5. Click OK to exit the dialog



Disable IPv6:

1. Hold the Windows key and type R, enter "ncpa.cpl" (without the quotes) and press Enter
2. Right click on each network connection and select "Properties"
3. Remove the checkmark from the box next to "Internet Protocol Version 6 (TCP/IPv6)
4. Click OK to exit the dialog

NOTE: You should do this for each network connection.



Disable the DHCP Broadcast Flag:

1. Hold the Windows key and type R, enter regedit and press Enter.
2. Locate and then click the following registry subkey:
3. HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters\Inter faces\{GUID}
4. In this registry path, click the (GUID) subkey to be updated.
5. If the key DhcpConnForceBroadcastFlag does not exist, use the Edit menu, point to New, and then click DWORD (32-bit) Value. In the New Value #1 box, type DhcpConnForceBroadcastFlag, and then press ENTER. If the key exists, skip this step.
6. Right-click DhcpConnForceBroadcastFlag, and then click Modify.
7. In the Value data box, type 0, and then click OK.
8. Close Registry Editor.

NOTE: You should do this for each and every GUID subkey.
NOTE2: (GUID) is a mnemonic for the individual subkeys, the actual text "GUID" does not appaer.




The only program I'm aware of that currently relies on IPv6 is the new Windows Meeting Space. The first 2 changes will cause that program not to work - but will leave all of your normal (IPv4) connections unaffected. If it causes problems that you can't overcome, simply revert back to the original settings.Vista compatibility with earlier versions of Windows.
On your Vista machine: Hold the Windows key and type R, enter regedit



Navigate to the following folder:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Lsa

In the right, double-click "LmCompatibilityLevel"

Change the value to 1 (probably currently 3)

Restart your computer

Ok, changed all that and ....no further access than what I already had.

So wired in the NAS's to a spare Linksys WAG354G, (didn't connect broadband as the its set for a different supplier) found the wireless network on the laptop and.....success, access to everything, streamed music, movies and photos.

That's kinda pointing me (right or wrong - all advice welcome) in the direction of the router setup and seeing as some of its been disabled in the re-branding from thomson to O2, I'll be phoning the supplier today.

If I get no joy with that is there any way of setting the two routers up together so one provides internet access and the other file sharing of NAS's. And from what you've seen of the setup I've got so far am I going in the right direction or is there an easier way to do this???

(I was also having problems with some web sites but as I didn't plug into the net and just used the wireless network, I couldn't check if these were router problems.)

Map the drive with an IP Address......and most of the time I get lucky and learn form these forums as well.

One issue I've run across with the Actiontec MI424WR that came with my Verizon FiOS service which may indicate you're on the right track.

When I got a new hardware version MI424WR to replace a failed one, suddenly network browser elections stopped working, so standard browsing didn't work without manually entering all the machines in the HOSTS file. Turned out that for some reason, the router was sucking up the master browser election packets and not allowing the election to complete. Removed the router from the mix, and everything started working again.

The way I solved this (since I need the Actiontec for the TV service), was to put a secondary router in the DMZ of the Actiontec, and use it for all the routing functions. The Actiontec just handles the Verizon functions for the TV.

Try sticking the other router behind this one in a similar manner and see if that works.

[Kruger2002]

Thanks JohnWill,
How do you do this as I'd like to keep the ADSL2+ speed of the O2 router for internet but need the linksys for the NAS's to work

[JohnWill]

Try configuring the Linksys as a wireless AP and see if they still work.

Connecting two (or more) SOHO broadband routers together.

Note: The "primary" router can be an actual router, a software gateway like Microsoft Internet Connection Sharing, or a server connection that has the capability to supply more than one IP address using DHCP server capability. No changes are made to the primary "router" configuration.

Configure the IP address of the secondary router(s) to be in the same subnet as the primary router, but out of the range of the DHCP server in the primary router. For instance DHCP server addresses 192.168.0.2 through 192.168.0.100, I'd assign the secondary router 192.168.0.254 as it's IP address, 192.168.0.253 for another router, etc.

Note: Do this first, as you will have to reboot the computer to connect to the router again for the remaining changes.

Disable the DHCP server in the secondary router.

Setup the wireless section just the way you would if it was the primary router, channels, encryption, etc.

Connect from the primary router's LAN port to one of the LAN ports on the secondary router. If there is no uplink port and neither of the routers have auto-sensing ports, use a cross-over cable. Leave the WAN port unconnected!

This procedure bypasses the routing function (NAT layer) and configures the router as a switch (or wireless access point for wireless routers).

[Kruger2002]

Just had another look at the Linksys router and its ADSL2+, its setup and works for both internet and file sharing with the NAS's so thats me kinda sorted.

I did try O2 help desk and they said they can only deal with broadband queries, not hardware setup....

Still, thanks for all the help and I know where to come next time I've an issue.

Regards

Mike
