Need For Speed 2015 Free Roam
Maryetta Worm
We are a small school district with several schools. At our HS we can have anywhere from 700-1000 devices on our IAP Clusters. We had an vendor originally configure out devices but I'm finding that they likely didn't know what they were doing. To combat the devices from "bogging down" a single AP they had enable Client Match, however for reading through forums I think they changed the default settings. What we were finding was that Chromebooks, and likely other devices, were constantly moving to other AP's and in the process would briefly lose thier internet connection which affected things like testing and Khan Academy exercises. For now I have disable client match to stop the complaints from piling up but there have been some speed complaints and that is likely because of large amounts of devices on a single AP. Other surrounding AP's, at times, are under utilized so that makes me think Client Match would be good but just needs to be fine tuned.
On another not, when devices were switching AP's due to client match the delay was enough to pop up warnings in the tests/Khan that the user didn't have internet connection. Would this be something that enabling Fast Roaming protocols could assist with or would that be too much overhead for the # of devices and our 43 AP cluster?
Yes. Uncheck 80mhz channels and Wide channels (results in 20 mhz channels). Clients will "stick" to 80mhz wide channels because clients have a higher association rate. Best to make it 20mhz that has more channels, less cochannel interference. What are your ARM Min and Max transmit power for the cluster? You might have to end up turning down the power. Start with the 20mhz wide channels first. Leaving off clientmatch is fine, for now.
It all depends. Many clients or devices cannot support 80mhz channels. In addition, having 80mhz channels causes alot of contention in high density areas, which decreases the speed. Lastly, most people do not run faster than gigabit ethernet to their access points or between their switches, so the theoretical maximum could not be approached, anyways.
Your ARM minimum and maximum should have a difference of at most 6 (12 min and 18 max, is a good start for example), so that it won't be possible to have access points with transmit power that vary much between each other.
I do have other schools using the Client Match. What are the default settings for CM calculating interval, neighbor matching %, CM threshold and SLB mode? Should the defaults be left for a situation like mine?
ClientMatch typically sends a deauth to the client. Most clients will reconnect automatically. Again, this is only for client where the AP thinks there is a much better AP that the client should be connecting to, or load balancing is involved. If you get the transmit power of your access points right, there will be less or little need for Client Match.
You could leave it on Auto. However, I suggest to take control and disable Mesh completely as a security and operational measure. Especially if you have no intentions to operate one or more WAX6xx as complete wire-free Mesh satellites.
to be fair one of these would have probably be fine if it wasnt for the fact that I rely on wifi calling as my network is trash here and the garden is pretty huge so need as much coverage as possible.
Good example where load balancing makes sense. Just to compare, if you would install the APs in the first and the third floor for example, it wouldn't. Living in a house with a similar floor plan btw, plus an underground work and garage space, have deployed APs to all floors, without load balancing in that case here.
if I set to 36 and 48 the graphs show an overlap... I am not seeing any intermittent issues as not picking up any neighboring signals but I feel like speeds could be better (for comparison my huawei ax3000 routers in AP mode where yielding faster speeds)
Keep in mind these channels are on DFS by all regulatory areas. Means the process can (and will) require one to ten minutes before the radio is allowed to become active on-air. Patience please, it' Wi-Fi 8-)
Consumer routers tend to be configured to the full available bandwidth, few offer dynamic bandwidth to the WiFi clients. Either way, don't expect to much from the theoretical graphs, generated based on the bandwidth in use, these are not spectrum analyzers for individual channel usage per 20 MHz bandwidth.
Afraid, no idea what this rotating LEDs indicate. How are these WAX615 powered - PoE switch (brand, model, firmware) or the ubiquitous power bricks as supplied with certain models? Could be a lost boot image for example, requiring service or some TFTP self-service. Please talk to Netgear support, I'm just yet another customer.
in my house I want to have only one WiFi network through four wired APs. So I reasearched a bit and found that I need a feature which is (sometimes) referred to as "fast roaming" or "seamless roaming".
Is OpenWRT supporting this somehow?
Is OpenWRT supporting this through cabled connections?
The situation:
Currently I am renovating a house that I bought and planning the WiFi network right now.
I am using OpenWRT on my router for several years now, so I got some experience with flashing and configuring.
This is why I am looking for OpenWRT capable APs.
The house has four floors (cellar, groundfloor, first and attic).
I placed network cables at all relevant locations, so I just need WiFi for mobile devices.
There is also one network cable for APs in good locations (only one wall to the other rooms) on each floor, so I can use PoE APs.
does this mean I will have four SSIDs in my house? I want to avoid that as this might not be accepted by my wife.
Or will I set up all four APs individually with same SSID, same settings and same WiFi password?
I Agree - basic (non-FT) roaming is already quite fast (except when using 802.1X/EAP). So unless you are walking around your house while in a Zoom/Teams session I would suggest to stick to the KISS principle and not enable 802.11r
I'd highly recommend that you watch the video that I linked in the thread I referenced above -- it goes through the principle of how to configure APs for high performance roaming. The basic concept is:
The other reason to have 802.11r in addition to teams etc. is interactive gaming in style of Clash of clans, where a war may get interrupted/defaulted/autoplayed to end if your phone decides to roam in the middle. 802.11r handles that nicely while ordinary basic roaming may quite much longer in reality than vendors claim.
I have a question here: What if devices with different specs using 802.11r on same SSID? For example, my main working area of course would be putting the best 802.11ax (maybe 4x4 160MHz), and then the other floor due to low usage I am putting an older 802.11ac (1x1) one, will this work?
I would say the reason is to practice with all the cars you want. It seems like they added it just for practice so everyone can get the feel of the cars for races without having to race multiple times before getting the feeling for the car down.
I wouldn't really complain. I bet if free roam wasn't included, there would be people saying "Why the hell is there no free roam!? I assume it's just to drive around, see the sights and explore the area.
But this is like a rehash of the original Hot Pursuit wich did not have any customization in the game. They is no need for it honestly. The majority of the cars are fast enough. Besides not having it in the game gives it a good balance and it shows online.
Performance modifications are pointless. If they make it so your opponents get faster as you upgrade your car then why even bother have performance upgrades? And if they just leave the opponent difficulty at a set level people kill just win by ridiculous amounts. Either way it's just a waste of time and adds nothing.
As for visual upgrades I'm glad they aren't here. 99% of the people that modify cars turn them into vomit inducing monstrosities. Every time I saw someone's modified SLR McLaren or Lamborghini Murcielago in past games I felt physically sick. You wouldn't paint over the Mona Lisa, and you shouldn't put parts that aren't even fit for a 20 year old Civic on a Pagani or Koenigsegg.
I really did play every need for speed that was released. - My dad used to buy them for me on release date for my computer when I was younger as I was facinated by cars - but did the game really have the EMP, helecopter, road blocks, spikes out of the back of your cars, etc. etc. ???
The ability to decide what time of day you wanted to drive. Totally turn off the day night cycle that is way to short imo. In Burnout you could set it to anything form 20 min to 24 hours. Or go by you local time. Or just have day all the time if you wanted to.
Tho some of these things I have mentioned here was not in Burnout paradise at launch. The day night cycle option was added way later. This game is still young. And Criterion added free roam stuff and options a few times long after Burnout came out. I expect nothing less for this game tbh. So fingers crossed that they do add some of this stuff later on for NFS down the line.
