RE: Transition to Eduroam

We're in the process of planning a cutover to Eduroam currently. My rough plan is: Get the new SSID stood up and operational. Transition a test set of users to make sure it's good to go. Send out messaging and training information for users and ask them to start using it on their devices. Go through ...

RE: SpeedQueen Laundry Machines and Gateways

Chris, are the laundry machines connecting to the gateway device via wired as well? Or are you talking about the connection for the gateway to phone home to the cloud? If the connections to the laundry machines are wired, I might go back and push them in that direction. David Hales Director of ...

Luckily we're not doing payments on them, so other than keeping them off my internal network, I don't have the PCI or security concerns that most might run into. Laundry is free in our residence halls, so they're just monitoring the usage and notify users when machines are available/done. We recommended ...

SpeedQueen Laundry Machines and Gateways

Our residential life folks contracted with a laundry vendor to install Speed Queen machines and some little gateways that will be used to monitor the machines and allow users to see availability, etc. The gateways turned out to be some flavor of Raspberry Pi with a little 2.4 GHz USB WiFi adapter. We ...

RE: Best DHCP Lease duration Practice for Small-Medium CANs?

I'm guessing we're going to hear a wide variety of stances on this. We use mostly private addressing with NAT and have pretty roomy subnets for our zones around campus. Because there's no resource contention for addresses we have our lease times set to 7 days for most of our networks. For devices that ...

Is that Keltron radio mesh system a communications network for the Simplex panels, or did that replace your panels entirely? We have the Simplex 4100 series panels around campus and would be interested in some way to get off of their fiber system as well. It's a really terrible system as was noted by ...

We're in much the same situation. We have used Procera for several years and really liked the performance and many of the other features it provided. We're in an firewall replacement cycle and plan to do the limited shaping we need (really just insuring that a few key services, like cloud backup from ...

RE: DFS Channels and Consumer Devices in Residence Halls?

Posted By David Hales 11-16-2023 03:14:14 PM
Found In Egroup: Wireless Local Area Networking \ view thread
We have run into a number of inexpensive consumer devices that won't do DFS channels but they just fallback to either another nearby non-DFS 5 GHz unit or the nearest 2.4 GHz unit. The biggest issue we had with DFS was a single AP at the top of a dorm that was able to "hear" a radar off in the distance ...

For the case where a user has three or more network devices, they will likely all be connected/associated with a minimum amount of maintenance traffic flowing (push notifications, feed polling, etc.) As far as higher bandwidth/active use, you can usually expect a maximum of three of them pushing significant ...

We've been using Qwilt on campus for several years now. It seems to cover a pretty wide set of content providers including streaming services, OS patches, and Game console content services. I haven't looked at the lineup lately, but mostly because the device just works without any intervention. I think ...

In working with Extreme on access point lead-time a couple of months ago, we learned that they were primarily having issues with availability on their BLE chipsets. The lead-times for APs without BLE were significantly shorter than for those with BLE. So many moving parts it's hard to tell what critical ...

We typically use preconfigured package equipment (office in a box) type setups that need minimal physical work for our remote sites. This allows us to just ship out replacements with documentation that allows the typical office worker to swap out equipment in a pinch. The one stumbling block is physical ...
