The company I work for has a wireless network setup on one of our VLANS. We are using Symbol handhelds and DSE wireless touchscreen computers.
I have found several problem situations with this installation. First, I wanted to add a wireless print server to connect a new printer in an area where we have good coverage. I selected the HP WP110. After I setup the print server I tested it on a Linksys AP I have in my office for testing purposes and it worked perfectly. I moved the print server out to the area covered by the AP4800E and found I couldn't ping it from a different VLAN. I could ping it from the same VLAN but then I would get a few responses then a few time outs. I also discovered I couldn't ping the Symbol handhelds from a different VLAN either. The DSE touchscreen computers have Cisco 350 cards in them and they function with no communication problems when associated with the AP4800E. I turned off "use proprietary extensions" on the AP4800E and could then communicate with the wireless print server from a different VLAN but still got "iffy" ping results.It appears that I'm having comm problems with any non-Cisco 802.11b device because when I tested my assumption by pinging the Symbol handhelds, I got the same spotty ping response that I got from the HP print server. This also explains why we have had intermittent service from the handheld computers.Now for the questions: the Cisco site leads one to believe it is possible to upgrade the AP4800E firmware with the 340/350 firmware.Is this true? If so will I get better non-Cisco device performance? If not, our version is currently v8.24, is a newer version for the 4800E available? I've seen a reference in the wireless forums alluding to this but haven't found it on the Cisco site.These units were purchased from the company that developed the softwarewe are using less than a year ago. Now I read the AP4800E is ancient. Is there any way to make the 4800E interoperable with non-Cisco stuff?
Just a couple of things to check. First when you were able to ping the device from within the VLAN but not from a different VLAN, did you verify all of the network settings (Default Gateway, Subnet mask). If that's all correct I would recomend if you have access to one, using a wireless sniffer to capture and possibly identify the problem(s). This print server is just a PC with a wireless NIC? What protocols are active on the NIC? Have you tried opening a TAC case with Cisco on this?

This is the start of a display filter cross reference between Wireshark and OmniPeek.
The 1st installment is a table of advanced filters. More filters will be added as time allows.
