DSM-G600, DNS-3xx and NSA-220 Hack Forum

First connect the laptop to the network using an ethernet cable - can you access the DNS-323 over wired?
Second - disconnect the ethernet cable and check the firewall and antivirus settings (for the wireless network) on the laptop - I've seen updates to the firewall and antivirus cause settings to change, especially as it relates to wireless which is sometimes tagged as "insecure"

OK...I have Symantec Endpoint Protection installed on my work laptop, but they don't really give us access to any settings - everything is pretty much greyed out.  Not sure if I'll be able to do anything there.

I'm going to test my wife's work laptop as well - just in case it's something on the home network that is different.  My wife just reminded me that I did upgrade to Norton Antivirus 2008 a few weeks ago on our home network - might be something in there that is different.  I didn't change any settings when I installed, but maybe the installation brought along some changes.

That tends to be a problem with corporate issued laptops.

Just a suggestion - with the laptop at work do an ipconfig and take note of the ip address range - when you get home set static ips on both the laptop and the DNS-323 within that range and see if you can get access that way - note - you should be able to communicate via the wireless even though you may be using a different ip address range.

If this works, you could consider changing your network to match the corporate address structure (assuming that is a private network range) - but - you need to be aware that if you use a VPN to get corporate access from home, this will break the VPN because the two subnets need to be different.

This does not compromise corporate security in any way, it simply makes use of a possible loophole that they may have been forced to leave open - in many cases the entire corporate network range is set as a trusted network.

OK...at work, on wired (they took out wireless a few months back - cost cutting)...

ipconfig /all output below...I don't see any info on IP range.  Is there another command, or is the lack of wireless at work going to stop this from helping, or ??

Thanks...so for example, say my laptop work IP is 10.20.30.104, I'll have to set my IPs on my home network so that my laptop and DNS-323 are 10.20.30.104 and 10.20.30.105, and then see if things connect.

If not, that likely means that my company has blocked wireless access to resources via the updated symantec SW.

I'm going to ask some friends at work if they're having problems as well...and if they've found a work-around. 

Thanks very much for your help and suggestions, fordem, very much appreciated.

Yes, you have the right idea as far as the ip addresses go - and the workgroup is not really an issue - you should be able to reach the DNS-323 by it's ip address regardless of the workgroup, but you could try changing the workgroup and see what happens.

Sheesh...severe public embarrassment will now ensue.    I owe you guys an apology, i've been wasting your time through a silly error on my part.

I was looking at settings on my Dlink router, and noticed in the logs that traffic from the DNS-323 MAC address had been blocked.

I looked in my MAC filter list, and sure enough, the DNS-323 MAC address was missing.

I had cleaned up a bunch of old MAC addresses from my "allowed" list a while back, due to some computer changes at home, and somewhere along the way accidentally deleted my DNS-323's address.  So still worked over wired, but was blocked from wireless.

I added the DSN-323 MAC address to the allowed list and the connection is working perfectly over wireless again, on both laptops.

Thanks very much for your patience and help.  Putting blanket over my head and slinking away now...

So it's not just me?!    Thanks for understanding...
