Wireless AP overrides adhoc network

By Bentz ·
I support a setup where users setup their laptops in a wireless adhoc environment. They travel to temporary clinics which could be a town hall, church basement etc... They all use Proxim Orinoco wireless cards on win95/98 ibm laptops.

I have setup static ip addresses in the 192.168.0.XXX range. (different ip for each laptop) I use the orinoco software to setup the network name, peer-to-peer type of network, channel, encryption. They all work great and connectivity is perfect.

The problem occurs when they go to a site where another wireless network exists. When this occurs the laptops connect to that network (through an access point) and override my ad hoc settings.

I have contacted Proxim/Orinoco on this problem and we went through changing the channel, the full ip address, changing the gateway, changing the network name. None of the options worked. The only thing that did work was disabling the encryption. At that point I got the networks running but now the encryption is disabled.

Since these are temporary clinics (lasts about 4 -6 hours) and are not in the same place every day and do not have internet access the security risk isn't as high. But the there still is a risk with client data.

I do not know who these other networks belong and am not able to do anything on their side. Just wondering if there is something I missed. It doesn't make sense to me that these access points can override my physical settings. Any ideas? Need more info? Just let me know. Thanks for any help on this

I'm not familiar with the orinoco but why couldn't you set a specific ssid on the card configuration. Then it would not roam to any available ap and connect. The adhoc configuration would then not get userped and overwritten.

Cheers.

Thanks for responding. I have setup the same SSID (network Name) in the card configuration for each notebook. They all have the same SSID, Channel, encryption key settings, subnet, and ip configuration (192.168.0.xxx range). I have tried using different SSID, Channel, encryption settings and IP addresses but still have the same problem. Thanks for trying.

Do you have multiple profiles set up (ie one for the adhoc and another one for the ap)? Also, do you want them to connect to the ap's at the clinic?

Cheers.

I only have one profile setup on each laptop. The profile is configured for the adhoc network. The issue with these temporary clinics is the AP's do not belong to the agency I work for. I don't even know what they could be for and do not want our laptops attempting to access them. Some of the clinics do not have a problem as there is no wireless network setup. But as wireless networks become more mainstream there are more of these appearing throughout the state (NH). Hope this answers your question and provides more information.

Hmmm. It must be an Orinoco issue. I set up a couple of pc's in adhoc and they never attempted to connect to my ap. I'm using netgear cards and ap on various os's. If you don't have to connect to a network while at the clinics you could have the user remove the cards while out of the office. Otherwise you could test with a differnet brand of card.

Sorry.

Thanks for trying. Unfortunately the wireless cards are specifically for the temp clinics. The all have regular nics to login to their main network back at their main office. They are setup wireless as they enter client information that is accessible when going from station to station in the temporary clinic. They remove the wireless cards when they finish with the temporary clinic.

Well, that's a little different situation then. Check out NetSelect or NetSwitcher:

Granted this won't help the problem with the wireless connection override it does resolve a separate problem I have with users that connect to 3 different main office sites.

This won't help if you don't have these options but in the configuration for my Intel Pro wireless card there are some Advanced Settings in the list of Profiles screen where I can set:
i) Connect to available network using profiles only, or
ii) Connect to Ad hoc networks only

I am new to this but was reading yesterday about the difference between Open Key and Shared Key WEP encryption. If you are using Open now then try changing to Shared.

Unfortunately there are not many other settings I can change for the orinoco cards. Thanks for the tip with about the intel cards for future reference.
