Yeah we have had this problem at a few different levels... sorry for the long response
Initially we had AARNET (the Australian national operator) sharing our floor, so we managed to experience the issue first hand. At that stage we got approval to change our SSID to resolve the issue. "eduroam-UofA" was chosen and our normal ssid is "UofA". To be honest this is not an ideal solution, and at the time (and probably still) is not actually allowed. It brakes the idea of eduroam simply working, the plan is you configure your device once and you can then go to any participating institution around the world, turn your device on and away you go. Having a different SSID means more support requests for you and the home institution when it doesn't just work. At the time (2007) the usage wasn't as high so it wasn't a huge issue..... though supplicants tended be troublesome to configure. A few years later AARnet offices moved and we wanted to be standard so we are back to "eduroam" SSID. It's not all over though, we have multiple institutions (3) around us offering eduroam including buildings 15m away, and a new medical precinct is being built that will potentially end up with 5 different institutions in an area. Finally something on the back burner is the our city wireless offering eduroam.... So the future will get interesting. But onto the current situation. To be honest at this point we haven't had too many issues recently with users hopping between SSID's in their offices. Likely the fact we don't recommend eduroam as the users primary SSID would be the primary reason. We did have a few calls on the close buildings years back, however coverage was done differently and it wasn't un-common in non-dense installs to sometimes see higher signal from neighbouring buildings in some rooms. But with denser deployments and more consistent signal provision you rarely see neighbouring buildings with higher signal.... In addition for eduroam visitors as a workaround they can use our "UofA" SSID, don't remember this ever being required but it does work. eduroam participation "requires" that SSID but as far as I'm aware doesn’t stop you from also offering it on others, or even wired dot1x for that matter. Likely we'll never go to eduroam as the only SSID for the many neighbours reason as well as it's good to have your branding in the air. You can also have issues like Curtis is mentioning where you want to change something for security or other reasons but may be restricted by eduroam policy. I don't think eduroam would approve of disabling 2.4ghz completely for example..... Our national document is being reviewed but currently states WPA-TKIP is required......HAHAHA. Don't think so. Finally we and other insinuations have wireless installs in our hospitals, recently the hospitals have provided blanket wireless coverage and interference became a major issue. The hospitals agreed to offer eduroam SSID, and we are all pulling out our gear. (so more similar to Ryan's experience). We started by disabling eduroam when they went live and now it's a working it's hardware removing time. In this case each of the 3 main Uni's here have a fibre into the hospital data centre and our users are routed directly to us giving us more control of their intranet access should we wish. A few discussions occurred about the varying technical solutions to all of above including the medical precinct and city wifi etc back in 2014. Things like SDN, Proxy Mobile IPv6 and routing for all users done centrally were thrown around but it all seemed a bit too early and we put it aside for now, I'm sure it's going to be back on the table in the near future. -- Jason Cook Technology Services The University of Adelaide, AUSTRALIA 5005 Ph : +61 8 8313 4800 -----Original Message----- From: The EDUCAUSE Wireless Issues Constituent Group Listserv [mailto:[email protected]] On Behalf Of Curtis K.

Luckily, eduroam is not our primary SSID so at least the critical business functions continue to work fine on a separate SSID. My guess is that we'll end up turning eduroam off at those remote locations if problems get reported. In talking with the eduroam admin from the other institution they mentioned that when this occurs in Europe the solution has been to change the name of the SSID. Is this really allowed? If so, I'm sold! Then we can start using our primary SSID with eduroam credentials! This is what I always thought eduroam should have been. To me the value was always in the universal credential *NOT* the SSID name. That was always a drawback for me especially as supplicants become easier to configure. The other problem that we're going to run into soon is that we will be phasing out PEAP on our main SSID to mitigate against the evil twin vulnerability, but what do we do with eduroam? I mean I guess you could say it is the remote institution's problem, or the user's problem if they connect to an evil twin on your campus because they're not validating the server. But if the evil twin is on your campus it seems you have at least some responsibility in the matter. But as it stands, eduroam will leave a bit of a gaping security hole for us. -- Curtis K.
