Hi Bryan, A few notes from our experience and our deployments recently.
8.2MR5 is a necessity if you are running X800 series AP’s. We had a slew of issues with 1810, 2800, 3800 AP’s when they first came out, but they are pretty solid now. We ended up going with 1810’s in our dorm’s to provide higher density, but also provide wired ports. The 1810’s are AC wave2, no CleanAir and only 2x2 but at the price point, it was worthwhile to get the coverage. We also started to put them into smaller team and study rooms. We weighed the 3800 and 2800 and settled on 2802i’s as our standard going forward. Although they didn’t support mGig, we can use both ports and push 2gig if needed. We do have a few 3800’s deployed but no mGig switches at this. From what we can see, we are bursting to around 200mb today at the switchport and that’s in dense areas. The 3800’s seemed interesting, but the only difference we could see was the mGig. We peaked out around 80 clients on a 3800 in the library during finals with no reported performance issues.

I think we’ll be making the switch to the 3800s – most likely the 3802E model as our existing APs are mainly wall-mounted. The E model has the advantage(?) over the I model in that only the I model supports macro/micro cell, which seems to be the cause of FRA issues in non-dense deployments. We certainly don’t have very many dense deployments. The 2800s also do sound like they could work for us, however our eventual goal is to support mGig on our APs. We have the wiring for it already. There’s also been some renewed talk about adding cellular radio modules (but I don’t want to get into that discussion here). The issues mentioned all seem to have known workarounds or have been fixed in newer code, and a most of you reported having success with these than not. We’ll advise our helpdesk to ensure that people with WiFi connectivity issues following the upgrade are running the latest drivers on their device. AC has been around long enough now that I feel the manufacturers of client devices should have their drivers fixed. One further question – how many connected clients are your 3800s able to serve before having performance issues?

For those of you that have Cisco 3800 series APs in production, how have they been working for you recently? We currently purchase 3700 series APs as our standard for new installs and replacement of our 3500 series APs, but are now considering switching to the 3800 series. I heard there were a lot of issues with them at first, but was wondering if they’re still troublesome now that they’ve been out in the wild for some time. Also, does anyone currently have issues using Prime to manage them?
