My Linksys mesh network is acting up. 2 nodes. One of them keeps going into red light mode after rebooting. The config page doesn’t show the 2nd node. The main node has 2 SSIDs. The main SSID and a guest one. For some reason nothing can get out to the internet on the main SSID but the guest one can get out. Sigh. I guess I’ll just reset these and start from scratch? I don’t mind doing it just busy rn and people using the network so can’t interrupt

wolrah posted:100% this, it's really easy to make an access point transmit strongly enough to be heard across a normal residence using high-gain antennas and turning up the power to the legal limits, but with the exception of desktop PCs you usually don't have the option to upgrade antennas nor the battery power to even consider high power levels. Even then pushing the limits of power tends to lead to lower signal quality so your increased range usually comes at the cost of performance. Imagine yelling in a house, but also needing to listen to what others (including in other houses) are yelling, so you can decide if it’s for you.

Am I looking at the wrong vendors/places or do 5GBASE-T switches barely exist? I'm looking at moving to faster than gigabit, and I'd rather jump to 5 gigabit if possible over 2.5, as I assume client devices that want bandwidth will be heading there in the next few years anyway.

Yeah on the PHY side everyone just sort of got on the train of the x4 or /4 lane game with the 1/10/40/100 hardware. Just go straight to 10G, with OM3 if you're going far. I ask myself in what possible future would I ever need 40G to my living room and then I ignore that voice.

KS posted:POE too useful. Mgig too common. Fiber a pain to deal with in walls. I still think "go fiber" is bad advice (except in the homelab thread maybe). I appreciate this and will look at Trendnet, I had not yet. It's not specifically that I want to max out at 5gig, but rather that I have a faulty mental model that 5gig should be significantly cheaper than 10gig. I know that SFP+ (and SFP28 and 56) are king in the DC, but all sorts of random consumer devices have 2.5gig now and the backwards compatibility to gigabit / 2.5G is just too appealing. I assumed that now that everything has 2.5G we'll see 5G start to pop up more on devices, and ideally I buy one better switch rather than buying a 2.5G switch and then a 5G/10GBase-T switch later. Mobos all have 1 or 2 2.5G ports now, even the cheapest consumer NASes have 2.5G ports, WAPs, it's just all over and a big cheap SFP+ switch wouldn't help with that. Don't a lot of the old/cheap enterprise 10G SFP+ NICs y'all are posting suck down a ton of energy and need airflow such that I'd have to zip-tie a little fan on them?

My problem with going to 10G is that my house's Cat6 all terminates in a box mounted between two studs with approximately 21"x15" inside. The 3850s start at 17.7" deep, so they definitely wouldn't fit. A Catalyst 9200L would work (well, might work- plugging in cables would be tight) but it's a bit expensive still. I'm currently using a MikroTik 24x1G + 2xSFP+ switch as the core, and with the use of a multi-gig SFP+ I can at least get 10G between the NAS in my wiring closet and my office. 2.5G/5G to the primary AP would be neat to play around with, but I'm getting PoE through a quad-port injector and I'm not sure if it could do >1G even if I had more multi-gig ports on the switch so I'd want the switch to do PoE as well ideally.

Not in my experience. They do use a few watts, but neither the intel or mellanox cards I have in use require extra cooling. I run 10gbe point to point with a DAC cable between my fileserver and my workstation, the rest of my network is 1gbit, and WAN is only 500mbit, so I don't really see the point in mgig for my use case, at least not yet. How much power does that Cisco switch use?

According to the data sheet, the WS-C3850-12X48U uses right around 200W regardless of traffic load. Of course, PoE clients will add to that. I guess that's another argument against it; if I look at the UPS right now which has my switch, PoE injector, and NAS they're only using around 165W combined. e: As far as transceiver power load goes I haven't noticed anything of concern with fiber or DAC, but some of the 10GBase-T units do get very hot. I actually ended up adding a USB fan to put some direct airflow on my MikroTik switch because when I first tried 10G through the wall, the MikroTik multi-gig SFP+ got up to 90C. The switch on the other end of that link is unmanaged so I wasn't able to get a reading, but the SFP itself was too hot to grip.

Yeah, I would strongly recommend avoiding that Cisco switch unless you already have a sizeable homelab, and at that point it would probably be better to find an SFP+ switch and use DAC cables for all the servers, and a (dumb) 2.5/5gbit PoE switch for APs and poo poo. 10GBase-T SFPs are banned where I work (I'm a network engineer at a metro authority  ) for good reason.

Mine's using 170W with 5 POE APs attached, so that data sheet seems off. Smaller switches: https://www.tp-link.com/us/business-networking/omada-switch-l3-l2-managed/tl-sg3210xhp-m2/ https://www.netgear.com/business/wired/switches/smart-cloud/ms510txup/ (That's assuming you want SFP+, there are cheaper options without) I agree that avoiding 10GBASE-T SFPs is worth it -- which is why I question recommending SFP+ switches. I guess if you're going fiber everywhere it's great, but otherwise you end up with multiple switches for mgig or POE stuff. KS fucked around with this message at 17:42 on Mar 26, 2024 |

Thanks for all the input, it's super helpful. I guess the short answer is "2.5G is all that makes sense right now on a limited dollars and power budget". Since y'all brought up DC stuff... it's super unclear to me how the different standards are backwards compatible (or not). You can do 100GbE over 10x10G on QSFP+, 4x25G on QSFP28, 2x50G on QSFP56, or 1x100G on SFP-DD. If I was going to snipe some cheapo cast-off enterprise stuff to do a single high-speed link, is QSFP28 backwards compatible to 10x10G, or are each of these fully incompatible with each other?

Twerk from Home posted:Thanks for all the input, it's super helpful. I guess the short answer is "2.5G is all that makes sense right now on a limited dollars and power budget". The answer here is "it depends" sadly. Some switches support basically anything 100G -> 1G on a single port if you buy the right gizmos to go in the holes iirc. Others it's very limited. You would need to check on a switch by switch basis, and I know you're asking for specific examples but I don't know them. Just showing you how to research it. I find it very confusing as well. It's why I wound up buying a cheap as poo poo 24 port 1G switch from one of the shadiest companies around.

For another power consumption info all i've got right now is limited to only what i've got plugged into it at the moment: 150W covers, including the PoE loads powered through it: The ONT UXG-Pro USW-Pro-24-PoE US-8-60W USW-Aggregation USW-Flex 2x USW-Flex-Mini's 2x U6-Enterprise 3x UAP-AC-Pros 1x UAP-AC-Lite UNVR 3x G5-Bullets a NAS an Arris NVG443B (relegated solely to a VLAN doing VOIP duty only.) and a pihole No 10GBase-T sucking up power, its all either DAC or OM3 So that Cisco switch looks like butt in comparison.

Yeah, I checked the data sheet again for that C3850 and the specific values given are limits at 0/10/100% traffic load. They don't say anything about how many ports are plugged in but it's probably all of them, which would definitely make a difference versus using just a few and having the rest shut down.

Cygni posted:is the home you are networking a Holiday Inn No I have more, its just on different circuits that I don't have a power monitor plugged into... But to hate on 10G-BaseT some more, waste heat grows pretty linearly with Frequency. So they run hot thanks to physics. While TAM and DSQ coding does spread the symbol rate over a large spectrum utilization as you go from 1G to 10G the power densities get ugly. For 2.5G for example you'll have spectrum low points at 2.5Ghz and 5Ghz with alias's in between them, now you integrate power over all that it gets to be alot. 5G is 2x worse, and 10G is 4x. To the point where each 10G copper link eats up 3-10W. Also 10G-BaseT adds like a 2us latency thanks to the encoding that fiber and DAC don't have to deal with.

So recently my ER-4 decided it wanted to forget about ever being associated with UISP, I couldn't get it to restore. Maybe it's a particularly nasty cosmic ray strike and it blew out the specific NAND cell that stored the info, either way I guess the unit needed replacement because it wouldn't accept the blue LED no matter what I tried. Managed to find a vendor that had the Cloud Gateway Ultra in stock and install was super easy. All I did was was launch the iOS app and it did all the hard stuff first; it updated the firmware on the CGU first, then the firmware for the lite 60 switch, then the U6-LR, incredibly it upgraded all the firmwares to the stable versions and in the right order and I didn't have to enter anything except new names and pws.. The end result was that I noticed the CGU made everything, well, snappier.. And I lucked out on the display screen, didn't seem crooked.. Long story short, the Cloud Gateway Ultra is a good choice to stay in the Ubiquity ecosystem.
