Some of this is very applicable even in a Cisco WLC environment. Such as making sure that you disable 1,2,5,and 9 mbps rates. The guide says to disable 11 as well, but I’ve found that some cheaper printers while they have the g radio and will connect at higher rates have to have at least the 11 mbps rate. Use device registration to get things like printer on the network or they will end up trashing your 2.4 with individuals setting up ad hoc everywhere. Make sure your basic rates have been set up to 12 and/or 24. Also set your beacon rate up to 12 mbps. There’s plenty other fun and games that can be done, but diching the lower rates has a pretty significate impact. Ultimately though, 2.4 GHz is just noisy. We polish it as best we can, but its still 2.4 GHz… Also check out: https://community.arubanetworks.com/t5/Validated-Reference-Design/Very-High-Density-802-11ac-Networks-Validated-Reference-Design/ta-p/230891 From: The EDUCAUSE Wireless Issues Community Group Listserv <[email protected]> On Behalf Of Michael Usher Sent: Tuesday, September 3, 2019 12:51 PM To: [email protected] Subject: Re: [WIRELESS-LAN] [Ext] Re: [WIRELESS-LAN] Residential Wireless and Gaming We are in the same situation. The way I look at it, the "basic network service" we provide in dorms is simply changing from wired to wireless. In fairness to other students, I think everyone should receive the same "basic" service. If an individual wants a wired port (assuming cabling is still there, and isn't Cat3), then I think "user pays" is appropriate for a "premium" level of service, along with installation and activation fees if needed. $100/yr seems very reasonable for the recurring charge.

We have a single AP per room in our traditional residential complexes. We profile gaming consoles and hand them a public IP address. We work with the students to make sure they are on 5Ghz if their device supports it. We try to minimize any interference from other devices in their rooms and their neighbors rooms. During testing, the user will consistently get between 40Mb and 50Mb download and upload speeds. Latency is always less than 20ms. The gamers still complain about lagging and glitching and rubber banding. You can provide amazing bandwidth and minimize latency as much as you want, but there is nothing you can do about the jitter that is inherent in a Wi-Fi network. Especially as groups of people congregate by the elevator (which happens to be right outside of this particular student’s room). As others have pointed out, there is no real fix. We haven’t decided to let the students plug in yet, but we are discussing it. / Stephen Belcher Director of Network Operations and Telecommunications WVU Information Technology Services One Waterfront Place / PO Box 6500 Morgantown, WV 26506 (304) 293-8440 office (681) 214-3389 mobile [email protected]<mailto:[email protected]> From: The EDUCAUSE Wireless Issues Community Group Listserv <[email protected]<mailto:[email protected]>> On Behalf Of John Turner Sent: Tuesday, September 3, 2019 10:45 AM To: [email protected]<mailto:[email protected]> Subject: Re: [WIRELESS-LAN] [Ext] Re: [WIRELESS-LAN] Residential Wireless and Gaming Hard core gamers will tell you wired is always better - they will also blame latency for their lack of skill ;-) However you CAN create a low latency small cell environment with hospitality AP's, DFS enabled, and a careful 2.4 plan. In the end you will still have issues with older clients and streaming hogs, but it's the best you can do. Yes AX sounds promising but we are years away from any meaningful adoption and bug fixes.

On Tue, Sep 3, 2019 at 10:38 AM Biggs, Nathanael <[email protected]<mailto:[email protected]>> wrote: High SNR and high RSSI are great, but most of the problems that I've experienced with our wireless come down to contention. Even if you've gone to a WAP-per-room wireless deployment in residential spaces, chances are you're still going to have 5-10 devices in each room. No matter how close you are to the AP, WiFi is still a contention-bound, half-duplex medium. This is exacerbated by everything Dan mentioned, but even with great WiFi, you're never going to get the low-latency full-duplex experience that you get with a wired connection (assuming that you do Gig-FD to your wired ports). Multiplayer games are really sensitive to latency, so any contention problems that automatically cause a device to back off from transmitting and wait for airtime could cause the problems you mentioned. 802.1ax is supposed to help a lot with this by breaking channels up in to sub-channels and scheduling airtime more effectively, but this will only work if every client that's talking has a fully-implemented, compliant AX chipset. No matter how up to date your AX WAP is, as soon as a legacy client chimes in, you're back to the contention-bound dark ages. This isn't to say that it's impossible to achieve performance sufficient for gamers on WiFi, but there are some physical limitations to the medium, especially when there's more than one device transmitting.

And, this isn't meant to be rude, because we are going through the same issues currently, but the only fix is better wireless. On the other hand, when students play from these consoles, they're really setting your team up behind the eight ball. These devices love the 2.4 spectrum and in dorms like ours (ranging from 20-100 yrs old), it's tough to make it work. The issue is unlikely a gaming specific issue. Gamers are just going to be the first ones to notice, and then speak up, about anything going on with the wireless. Do a packet capture and have a look at the retry rate where people are complaining. I think that's a good starting point.

At quick glance, the rssi and snr shouldn't be an issue. They even state that access to campus resources and other internet activity is not an issue. We have not begun to deep dive into this issue.
