Huh, haven't looked at the plots for my new U6 APs yet. Glad I went with getting the "U" to look right which coincidentally seems to match my usage... interesting that one side of the U6 Pro is a good 5 dB weaker than the other side. Good thing it's in a corner of my room!

Hoping to get a sanity check please: Current setup: ER-X > UAP (via POE injector) + TP-Link camera (via POE injector) This works OK but is stuck with 2.4 GHz, no support and no way to expand as there is no switch next to these devices. So my TV, Apple TV etc. are using Wi-Fi. Proposed setup: ER-X > Edgeswitch 10XP > Unifi AP 6 Lite + TP-Link camera + Samsung TV + Apple TV + (future camera) Am I correct that the ES-10XP would power the AP and camera (+another in future) via POE? TP-Link camera says 12V DC, Max 12W.

Happy Pizza Guy posted:I'm moving to a new home and I'm facing the age-old dilemma of a 3-story brick rowhome that is only wired for coaxial. I've had good luck with MoCA in the past, so I'm hoping the previous owner of the house wired the coaxial properly and I can use it to have wired networking in most of my home. This is me right now, bought a 4 floor row home only two rooms have ethernet, the fios ONT (300/300) in a room with only access to coax. So i put in a ERX at the ONT, and a moca 2.5 adapter to the basement and into a switch. from the switch i have ethernet drops in the living room (second floor/above basement) and master bedroom (top floor) issue is that the basement, guest bedroom, and master bathroom gets poor signal. Parking pad gets a signal but not useable at all. i have ai mesh set up to drop clients once they fall below 400db but i need it to drop at even lower reads so i can put more APs in

i wish I knew MoCA was a thing before I tore out a bunch of my coax runs the previous owner put in. I mean none of it was professional, holes in floors and run along baseboards etc, but it's all work I had to re-do with ethernet when I could have put it off for a bit. And now I'm kind of thinking of re-doing the backhaul upstairs with fiber anyway, as an easy path to 10gbe down the road. Thankfully I put up a bunch of conduit so stringing new cable is easy for 99% of the run, just need to figure out how to terminate it upstairs. With twisted pair I just terminate it to a a wall box after the cable emerges from the cool totally-code-compliant hole in the floor. With fiber I guess I need to route it to its uplink, unless there's a fiber equivalent of a twisted pair junction keystone jack, which seems iffy given you're talking about optical carriers with a lot less margin for error. e: I mean pragmatically, without specialized equipment, etc. Obviously you can money at this kind of problem.

So my ISP is offering to take me to gigabit (940-50 Mb/sec down, 50 Mb / sec up) for a decent amount of $$$ (something like $18-20 extra per month) and I'm wondering if I should either convert an old 2012 quadcore Mini to pfSense or just get an EdgeRouter 4. Currently I've got about 30 devices hooked up to the current EdgeRouter X, a big part of getting the ER4 is that it's managed mostly the same way as the ER-X so it should be quick to set up for me. There's still hardware offloading but it's just slightly different commands. The ER-X is handling 400 Mb/sec like a champ, CPU never really goes over 11-13%, but RAM / storage sometimes needs janitoring. Furthermore, the ER-X has a switch chip and the ER-4 doesn't; I can take the ER-X and convert it to a Layer 2 switch and hang my two APs off of it, and hang it off the ER-4. Flip side is that the Mini running pfSense will probably be more powerful than an ER-4, and I can run the WAN into the Mini's built-in Ethernet but the only other connections I can have are one Apple Thunderbolt 2 to Ethernet and maybe 4 USB to Ethernet dongles, which when I checked with pfSense says are fully supported as interfaces. I'd probably hang the ER-X off the TB-Ethernet dongle since that's the fastest. Anyone see any flaws in this scheme? No, I don't want a TP-Link.

I would have thought ER-X would be "mostly" fine for gigabit with offloading enabled. That is to say, my vague recollection was that it's supposed to do cumulative gigabit so you'd never actually get 1000 up AND down before you bog it down, but depending on your usage patterns the two might not conflict enough to be noticeable unless you're constantly streaming and downloading at the same time? I'd probably go with dedicated hardware if it were me. The thought of trying to monkey with pfsense on a mac makes me uncomfortable though it's probably "fine". If I had to go pfsense I'd probably get a small lenovo 1L desktop and hang a few USB3 interfaces off that I guess. Or a small SFF with a quad NIC. some kinda jackal fucked around with this message at 17:36 on Feb 7, 2022 |

Martytoof posted:I would have thought ER-X would be "mostly" fine for gigabit with offloading enabled. I seem to recall the same but a brief internet skim seems to indicate the “numbered routers” (e.g. ERL-3, ER-4) are more capable. FWIW - I like my ER-4. Though to be fair, I have single mode fiber throughout my house so the backbone between all the router/switches is SM and that was a specific selling point for me getting the ER-4 versus something like the ERL-3 (what I upgraded from).

Man so apropos of nothing, I don't want to power all my APs and mini-switches with a PoE Ubiquiti switch for reasons, but also the idea of having like 4 separate PoE injectors is abhorrent to me for some reason, when they're all being powered at the source. I ended up buying a TrendNet 802.3at PoE+ 4-port injector on Amazon just now. My understanding is that it'll back-negotiate with 802.3af PoE devices and the only ones out are passive PoE which I have none of. Currently powering UAP-AC-Pro, UAP-AC-LR, USW-Flex-Mini, and UAP-AC-IW (which will power a downstream USW-Flex-Mini I guess) so hopefully everything works as I envision it. For the life of me I can't figure out why Ubiquiti has like 400 injectors in their lineup. Nothing has made me second guess my understanding of PoE more than reading through their Injector catalogue.

I do remote out via work VPN quite a bit, which is one of the things that's currently offloaded. One thing that concerns me is that the ISP (Optimum in this case) claims that they will test my ER-X to see if it handles gigabit ok, and if it doesn't they're going to shove one of those Altice units in my face. If they tell me the ER-X can't hack it I'm going to tell them to call it off as I really don't want a router that I can't janitor.

I actually really despise vendor-specific certifications, but Cisco’s CCNA curriculum was where I cut my teeth, like decades ago, and the fundamentals will still not have changed. Feel free to skip the vendor specific stuff if you’re just looking for fundamentals, but I think going through some video courses is probably your best bet until you want to get hands on. Or honestly, I don’t know what the marketplace for training is like now, but I 100% believe that if you have a public library card you probably have access to lynda/linkedin learning/etc and you can find networking basics video courses. That’s not even taking into consideration the vast array of youtube stuff. I think CCNA curriculum is probably tried-and-proven, but there may now be better avenues if you’re not going to actually write the CCNA.

No prob! I don't know if you're anything like me and learn better by DOING then definitely get yourself hands on with wireshark to actually see the stuff happening under the scenes. Tools to help you would be GNS3 for topology an device emulation, wireshark and tcpdump for low level capture and inspection, etc. I would be surprised if SH/SC didn't have a dedicated (enterprise) networking nerds thread if you want to ask any specific questions as you move through your learning, but I suspect if it does exist it's probably a lot of the same players as you see here. By sheer coincidence a friend-of-a-friend asked me yesterday to recommend something along the same lines for their daughter who is starting to show interest in understanding what's actually going on behind the scenes, so I feel compelled to actually research more of a concrete answer with specific resources that I guess I'll share once I get around to doing a little research.

Neat That's about what I would have expected but there are some surprises there like that in wall HD. I'm especially interested to see how this is going to pan out with 6GHz when vendors no longer offer external antennae options (such as Aruba, at least). For the most part treating the donut APs as omni directional works, though that rear output has been a pain in the rear end before. I did some work to improve system performance in a LEED Gold commercial building, where the radiation from the rear of the ceiling mounted APs penetrated the floors enough to cause issues with auto system calibration resulting in low power levels and poor coverage. I'd imagine most residential can be treated the same way, that most surfaces are going to be largely RF transparent, and then at high power levels of having an AP in the middle of the house, between multipath and drywall/wood it may as well be a spherical radiator. As far as learning I can recommend a Discord community that would help if you want to go down the CCNA track, though there are plenty of free or low cost resources available for self study on Youtube, Udemy, etc. Cheap course from David Bombal with lab examples. I still believe the CCNA represents a decent foundation for anyone who's going to be interacting with network elements directly, and needs to know more than the basics about addressing and IP connectivity. I've helped a few friends work through the CCNA curriculum in the past who got hung up on subnetting or spanning tree, neither of which is extremely necessary to master IMO to have an awareness of network concepts. Just learning the functions of these things may be enough without getting into how they work, bridge elections, what CIDR is, etc. I wanted to make a post about VLANs and IoT just to share my thoughts on that but after how well my candle analogy went off I might have to think it through.

Ugh I'm at that stage of finishing my network cabinet where everything is held together with the "temporary" patch cables I could find and it's time to start measuring and ordering ones that are fit for purpose. I'm having that weird internal struggle trying to stay motivated now that I have most things working how I want and a big part of me is just like "eh dude do it later" but then I look at the cabinet and it's just got random loops of cable sticking out everywhere and there's no way this will stand. Any thoughts on those ultra-slim patch cables? I'm not exactly sure what the catch is, being so lithe.

They work - if you’re taking like the 28awg cat6a. One of the RCDD fellows I worked with had told me they cause derating or certification issues. But they work for PoE and gigabit. I don’t know if we have any mgig channels running over them faster.
