Problem using router as master browser

[Rille_lkp]

Just installed this firmware (23b) to get the option to use my router as master browser but i'm having some problems with my PCs running linux.
From my Windows PCs i can browse WORKGROUP and i see all PCs (including linux machines) and access them.
On my linux PCs i can however not browse WORKGROUP. If i try from my HTPCs running OpenELEC (linux+XBMC) i just get an "operation not permitted" while i can access SMB://HOSTNAME. I then tried installing Ubuntu and when i try to open WORKGROUP there it asks for username/password which i believe is what's causing the problem for my HTPCs.
Any ideas why linux machines can't browse WORKGROUP and asks for password?

*EDIT*
Also tried browsing the network from my Android phone and tablet which are also unable to browse WORKGROUP.

Found a solution to the problem, adding these lines to the clients smb.conf helps:
lanman auth = yes
client lanman auth = yes
client plaintext auth = yes

Is there anything i can change on the router so that adding these lines is not needed?

To clarify, this is not a problem accessing computers in the workgroup. It's a problem accessing WORKGROUP.

Hi,

You can use "Custom config files" (details on Merlin's wiki page) to add things into the smb.conf of the router.

With kind regards
Joe

PS.: Had the same problem and fixed it by changing the Windows Clients and the router smb.conf (is an XOR sulution, but just in case, both options are there).

FYI, in case if you are having the "Unable to find the Domain Master Browser name xxxx<1b>" issue: it looks like that I have been able to fix it on my router by forcing Samba to be Master Browser through the UI. Look for the option under "USB Application - Network Place(Samba) Share / Cloud Disk"
