Sickening posted:Ap Density status: THICK Lmbo Its unfortunately not that simple. I am consulting at a fortune 100 as a wifi SME. I had Cisco advanced services do a site survey for a high density initiative and overshared the results without an executive summary, so now high level people believe all the wireless is hosed and wants answers. Despite our best efforts we havent been able to get through to them that the current coverage is adequate for non-critical use but needs improvement for voice class coverage.

 Same company I've been at since 2013, but moving up from NOC Engineer to corporate trainer for the NOC. Going from hourly to salaried (with no on-call expectations) and a 12% raise. Responsibilities (beyond training new people) will involve creating and maintaining SOPs and documentation as well as helping to work out new processes as our tools and customers change. Anyone familiar with a role like this and/or have things to keep in mind?

I agree, but it's where things are going. 802.11ax is supposed to improve voice over wireless quite a bit since the spec is designed for low latency, whereas ac was designed for high bandwidth. We'll see how it looks next year I guess. Docjowles posted:"not as dense as you, apparently" He's not an idiot, just unfortunately overworked and can't spend enough cycles on one particular subject. His department is responsible for reviewing and approving every single infrastructure upgrade (software or hardware) for the company and also is expected to lead innovation. Enabling cdp requires review. The red tape slows things down and he has to deal with that.

Trying to tell someone the difference between signal strength, coverage, negotiated speed vs actual throughput along with any latency terms when they want to use them interchangeably. Then there's the whole "I see 5 bars but nothing works". 'Well you see boss, someone turned the boost and power up on the AP with these high gain antennas so high your phone seems to be detecting a very strong signal but like a small child trying to throw a football to a player from the NFL while he can receive the pass, its unlikely he'll be strong enough to-' "JUST FIX THE drat WIFI WE HAVE! AGRGGRGRGRGGHG" Also radios. Explaining interference and why their 2.4Ghz implementation from almost a decade ago isn't designed for today and any inherent issues with that. Then getting blamed for apps so shittily coded they cannot tolerate 1-3 packet drops ever even though 99% of all modern ones don't have an issue. "Stop deflecting the blame to our app team they work very hard with those error messages stating its a network problem!" Fun times.

That explains issues with things like Skype calls being awful and it’s not actually the client but the network. I wonder if this would impact games too. Most pro gamers always have a wired connection.

You can't fully replace wired due to current wireless being half duplex and easily influenced by incidental interference. 802.11ax won't change either of those things

True but almost every instance of that problem is always due to poor RF design. APs installed to transmit at full power when client devices are only transmitting at 15mw leads to client stickiness and duty cycles being full of retransmits. I cant think of a single time I've evaluated a wireless network, paid or just curious and said "wow good RF design"

Those were the days, 100 people crammed into a large conference room with personal phones on guest, their laptops on corporate net, and their company phones on the same AP.

And to be honest, most of the RTS/CRS floods I’ve seen are on 2.4 networks to which my first question is “why the gently caress are you still using 2.4 networks”. And on channel 11 next to a break room with a bunch of MW ovens. And then there’s “a site survey? We just placed them where we thought it made sense. Also what are these channels you keep going on about?” God drat, I don’t miss those days that’s for sure. It was interesting and I learned a lot, but I’m so glad I’m back doing security stuff.

Oh I've got more. Machines in manufacturing areas as tall as a ceiling built around the APs so a nice metal cage around them. Warehouses changing their metal shelf locations with boxes stacked like a fortress filled full of metal parts and pipes in areas where people used to work and then the old areas where they couldn't walk and had no coverage now converted into work areas because "we got a new manager and he wanted us to move poo poo around to look like he was doing something". "We don't have enough wifi in here." Buys three different band APs with three different controllers broadcasting the same SSIDs. The installs all of the APs right next to each other in the same building. So Cisco, Aruba, and Ubiquity APs stacked side by side also oriented wrong or upside down, or like an AP sandwich with various APs taking turns in the "middle". Its a global problem. Its like running ekahau software in a hotel. Get ready for supercells and everything on the same channel in triplicate. Then there are the places that get construction done and they bury an AP in the wall like the cask of Amontillado. Hearing its dying ghostly whimpers in the walls beyond, forever beyond maintenance and with it being powered externally always even after the controllers and other APs were retired long ago. edit:correctedededed, e-males I am Communist fucked around with this message at 20:25 on Aug 9, 2018 |

Two friends of mine do my old job at my old employer. Their stories continue to make me glad I moved on. Meanwhile, I just reluctantly threw my hat into the ring for a slightly higher position in my department, so I’d go from “Lead Tech” to “Student Information System Specialist / Database Programmer”. So instead of doing and delegating tickets and also projects, I’d keep my same projects, which I enjoy, but trade the crappy part for writing some sql queries. I think it was smart to let them post the job publicly first to see what kind of candidates they’d be able to land (it was not good). It’s nice not being desperate. If the money’s good, then great. If not... good luck! In personal news: my tinybab might come home soon. She’s over 5lbs 3oz now and we’re really excited.

Wireless stories are the best. When MSG had it's billion dollar renovation they paid several million for a wireless survey, which was done wrong. They then had to spend several million more for a second one! When I was doing service provider wi-fi my team and I would find directional antennas pointing downwards off of a telephone pole or beaming into areas 180 degrees away from their intended LOS. Every time we sent them to our boss he'd lose his drat mind. We also had cisco connect an antenna to the top of a BMW X5 and do 100mph sprints down a runway to test wifi on a commuter train. Somewhere someone thought that was a good enough proof of concept to start installing them on NJ Rail cars. Didn't go well.

At the time we were paying 4 million a year for advanced services to POC poo poo, I don't think that particular role exists anymore. But if it does its Cisco Advanced Services. Edit: Also it was M5, not X5 whoops Edit2: Also if you're curious, the M5 was basically loaded with antennas going into a Lilee box made by these https://www.lileesystems.com/passenger-connectivity/ cool concept but probably ahead of it's time. It basically is a wireless controller with a 4g backhaul if wifi is unavailable (which is always). You could do it on the cheap with a cradlepoint. The goal was to put high gain APs along the railway but each AP installed was estimated at 250k and no one was going to spend 300 million on free loving wifi Sepist fucked around with this message at 20:42 on Aug 9, 2018 |

There's so many charlatans in the Wi-Fi survey space though. One company we used to use would magically determine that the best location for the APs was right next to the places that were easy to get cables to.

Thanks Ants posted:There's so many charlatans in the Wi-Fi survey space though. One company we used to use would magically determine that the best location for the APs was right next to the places that were easy to get cables to. I feel this comes largely from the fact that a lot of businesses looking to install "better WiFi" are not looking to improve their coverage for mobile devices and things that should be wireless, but instead are trying to use WiFi for stationary PCs so they can cram more people in the same space without adding wiring. Adding wiring for the WAPs thus isn't very easy to sell them on.

I'm about 5 months into a support technician gig with my local public school system and am slightly freaking out. The school year here starts on Tuesday and all hell is breaking loose right now... for everyone but me. Which is actually kind of scary, because I've only been at this job since May so I have this feeling that there must be some sort of massive, important thing that I'm obviously forgetting (I'm extremely scatterbrained and have a memory like a sieve), but I've been sitting here racking my brain trying to figure out what and I'm coming up with just a few small, low-priority items. I feel like there's just no WAY I could have actually kept three schools worth of poo poo together without losing something, forgetting something, or otherwise overlooking something incredibly obvious. On the other hand, I have gone through at least 100 post-it notes this summer, so... maybe that combined with keeping lots of reminders on my phone helped enough? I wonder how many notes and post-its I forgot to write? It's just that lurking feeling that something massive that I should have caught is out there, just waiting to drop at the worst possible moment, that's been driving me nuts. Does that ever stop?

Sorry for the incoming rant but holy gently caress am I about ready to throw my phone out of the window. Every semester we have issues with a certain textbook publisher where some students are unable to log in to their website to see their book or do homework. When this happens, the publisher’s tier 1 support usually tells the students to contact us, even though we don’t have access to their system at all much less any ability to gently caress around with accounts. So, we e-mail their supervisor to remind them that this isn’t something we can fix, and the problem gets sorted out. We have complained all the way up the chain to the Vice President of the company about how stupid this, but apparently their support team has a high turnover rate, so the training never actually sticks. A month and a half ago when this happened in a few summer classes, I was told by the new supervisor that there is someone at our school who has admin access to their system. I asked who this person was multiple times over the next week and never received a response. No one in my office was aware of anyone at the school who does this. It happened again this week. This time, one of the publisher’s support staff TOLD THE loving STUDENT to call us so that we could contact their supervisor and have the problem resolved. I called the supervisor, who also refused to help the student and argued with me for over 30 minutes about whether someone at our school should be the one fixing the problem. I again asked who that person was, and they said they’d have to get back to me. I told them that they needed to help the student before she started missing homework assignments, and they assured me that they would. The next day they called me back and gave me the name of the person who could supposedly fix this, but that they were unable to reach him by phone. No one in my office had ever even heard this name before. When I looked him up, he was listed as an adjunct professor in our math department. The supervisor said that this professor has apparently been on vacation, and that is why they didn’t get back to me with his name in June. I told them to call me back whenever they got through to him. I also tried to call him myself but did not get an answer. Today, I received an e-mail again telling me that this professor was the person we needed to contact and that the student could not be helped until he answered. I responded with a list of 10 previous tickets in which we were able to get students’ problems solved by contacting the old supervisor. A few minutes later, I received a phone call from the new supervisor’s boss. She explained that student accounts are created in batches and that in EVERY SINGLE CASE that we had e-mailed the old supervisor, the student’s “batch” had just not been created yet. In the biggest coincidence ever, the students’ accounts were ALWAYS created in between them complaining to us and us contacting the supervisor. I asked why this still hasn’t happened with the most recent student yet, and she told me that when they called the student to get more information, the student told them they were busy and asked them to call again later (I have since e-mailed the student who does not remember this phone call taking place). I also asked how it came to be that a random professor got admin rights to their service, to which she said she didn’t know. I don’t know what to do at this point. I don’t believe them that they’ve never been able to solve the problem, because there is no way in hell that it’s just magically been fixing itself at the exact moment we need it to every single time. Until I find out who this professor is and why he has the responsibility of overseeing something like this, provided he actually does, any student who can’t log in is apparently just hosed.
