If you're in Europe you might wanna use Tele2s Speedtest service since they offer 10Gbps anycast servers well-distributed in Europe (although if you're in the US and testing up to +1Gbps, the bandwidth delay product from the US shouldn't be an issue). Also, while it's a popular option for reasons I'm not entirely sure about, you may want to avoid using iperf3 - since is designed intentionally to be single-threaded because this design doesn't run into some of the issues that the Linux netstack has with multi-threading. There's also a bunch of minor differences that you're probably unlikely to run into, if you just want to see some numbers. BlankSystemDaemon fucked around with this message at 14:27 on Jan 22, 2022 |

The problem with expecting all of those features is that DFS is the only one that's required by law (because of the 5GHz ISM band intersecting with radar) - so ODMs will cut out anything that isn't required by law to produce a cheaper product so they can make money on the margins.

Since the APs have to have power, it always seemed easier to me to use PoE. In addition to that, I blame CCIE Wireless for knowing too much about 802.11 to the point that I don't trust it.

Are there any services you're accessing which are IPv6-only? If not, I can't see that there's a good reason to spend the money - especially when you can setup a tunnel to Hurricane Electric in order to get IPv6 for free. Alternatively, if you have a server with IPv6 and ssh access, you can ssh -D 1080, then configure your browser to proxy via SOCKS5 on localhost:1080 and tell the browser to send DNS over the proxy.

Speaking of switches, are 6 port 1GBaseT NICs still a thing, like it used to be with 6-port 100BaseTX NICs? Because with netmap(4) in FreeBSD, I'm pretty sure it should be possible to do in-kernel switching for up to 36 ports (ie. 72Gbps bi-directionally, which I remember it topping out at on at-the-time old hardware some number of years ago) on a standard motherboard with five daugherboards, while using the NIC on the motherboard/CPU for WAN. EDIT: Apparently it is, and there's even a SFP model. EDIT2: Now I'm thinking about how this could be used to build an all-in-one router+switch+database+fileserver+mediacenter+workstation virtualization monster.

The Unifi Security Gateway I have does it, and that's super low-end (only capable of doing 1/1Gbps because of the ASIC included next to the CN5020, which is really just a 500MHz MIPS64 SoC with 512MB RAM and 4GB storage), so I imagine there's lots of gear that does it.

Actuarial Fables posted:Thankfully it was classified as an "installation" issue so I didn't get charged for it. The tech replaced the ONT with a fiber outlet and changed out the previous router with a "BGW320-500", so I think I got an upgrade. I'd like to use my own gear, but the WiFi (4x4ax) outclasses my AP (2x2ac) and I don't have a router that can take an SFP module, so maybe I'll rework my setup instead. 802.11ax has its own set of problems: This one is mostly for for battery-powered devices, but the fast fourier transformations and forward error correction are always active and computing them require considerable amount of power. There's also the issue that it's primarily designed for many simultaneous low-rate data transmissions whereas typical web-browsing consists largely of few high-rate data transmissions. OFDMA is also inheritly more subject to inter-cell and intra-cell interference, which means that if you're in a highly congested area and your neighbours have 802.11ax setup as well, the closer you get to their cell the lower signal strength you'll have unless the base stations are talking to each other which they won't be, since they're on separate networks. This is further complicated by the use of higher frequencies, which get worse and worse at penetrating any building material as you approach the upper end of the ISM bands. Also, radiation patterning might be better, although there's really no way to know that except to plot it - but at least it's one of the areas where there's still a good correlation between the manufacturing cost of a device (which is always very low for CPE, which are built down to a price) and the result you get. If it was me making the decision, I'd probably stick with your old AP, if you know that one works well.

Eletriarnation posted:Is it actually a common scenario to have so many rogue networks around that even 5GHz won't deliver acceptable performance? Between poor penetration for a lot of building materials and the number of available channels, I haven't ever seen that personally but I'm also not trying to implement Wi-Fi in high-rise apartments. In addition to that, the 5GHz band is an ISM spectrum so there's no reason to believe more devices won't take advantage of the unlicensed nature of that up to the legal limits - so even if it isn't crowded right now (which is an untested hypothesis), it probably will be in the future because there's no point at which airtime availability in the ISM bands has outpaced the number of new devices being added vs the number of old devices being removed.

There’s always a chance that it might be available in the future but the truth is supporting our regulations just isn’t the primary focus. From my understanding even the 660HD and 620HD don’t, but the EU firmware does. And the forum support being largely one account that will “pass on suggestions/questions” isn’t great either.

You have one of two options: 1: A RIPE Atlas probe (it's free if they approve your request - usually it's no problem to get approval). Atlas is a internet measuring system whereby RIPE collects and publishes all the anonymized connection, and if you participate by hosting a probe, you earn credits to be able to set up your own measurements (in addition to the ones automatically performed by RIPE in order to provide the basic functionality). 2: Setup smokeping. This is a lot more work - in addition to setting up smokeping itself, finding servers to ping arbitrarily that won't oppotunistically drop your data like a lot of internet routers and public endpoints (like DNS servers) will, is no small task. Those are pretty much the only tools that're universally recognized for this kind of thing - but if your ISp is lovely enough, they might refuse to even acknowledge the data generated by either, in which case there's pretty much nothing you can do other than keep going through their script and demanding to be escalated to a higher tier.

movax posted:feed my itch to have every possible slot populated and in use.  Does the machine have a SIM slot, or are you planning on using eSIM for the WWAN NIC? You should probably also figure out if the WWAN modem is supported in FreeBSD, as the vast majority of the ones on M.2 or mini-pcie aren't - since almost all new WWAN NICs use the proprietary standard caled QMI (which is barely supported on Linux, let alone anything else - so maybe the best option is to pass it through to a Linux guest which can then bridge it with a virtual NIC you've got connected to your router guest OS). As for memory negotiation, I have at least one piece of gear at home that refuses to boot with CL16 memory, but will boot just fine with CL17.  Maybe dmidecode can help figure out memory training? If you're doing Proxmox, I hope the system has SR-IOV support as that makes virtualization of NICs much simpler.

movax posted:Nah — the WWAN slot is physically not present / I’m not sure it would work if I soldered a connector on it. No one seems to make a LTE 2230 modem, but it seems like a GPS module might exist (lots of 2242, not a lot of 2230 sadly) from a few random companies. Or I’ll design a board for some u.blox module in 2230 and FOSS the files. There's good news on the gps front, astro/gpsd works well - at least when I tested it with the Sony Ericsson F5521gw that was in my T420 for years before the HSPA network closed in Denmark. Also, PPS_SYNC has been in the kernel since October last year. Currently I have a Intel XMM7360 WWAN NIC in my T480s - but as is the case with ThinkPads, some of the devices are firmware locked and I don't think the T480s firmware has been hacked yet. Unfortunately it isn't supported yet in FreeBSD either, so I may have to throw NetBSD in a bhyve guest and use PCI passthrough and bridging there at some point when I get around to it. As an alternative to QMI, there's always MBIM - which has been making a bit of progress lately. The advantage of SR-IOV is that it makes one device appear as anywhere from 16 to 64 devices attached directly on the PCI bus, depending on how you configure the virtual functions. Each one can be used with a separate guest by the hypervisor (or as a FreeBSD jail network device), without a need for the typical vSwitch configuration.

If you need to stream content, please pay for any number of semi-shady companies that specialize in avoiding streaming blocks that do logging despite claiming not to, because that takes up a large portion of bandwidth of free and legitimately useful VPN services and will eventually get the hosts blocked by the streaming companies anyway.

Scratch that, not with those frequencies, and not if you're in Usania. Still, if the error correction that's used is Reed-Solomon (used in everything from RAID, CDs, DVDs, BluRay, DVB-C/S, ATSC, WiMAX, QR codes and many other things) or newer, and it can't cope, there's something wrong with the medium it's being sent on. EDIT: It is using Reed-Solomon, so tell them to replace their lovely copper and stop claiming "everything is good on their end". EDIT2: Oh, also I forgot how far DVB-C goes nowadays:  699MHz is still outside the range you'd find in any European network though, so I wasn't completely off-base. EDIT3: The fact that the EMI is spread over such a big part of the spectrum suggests that you should maybe also contact your local signal authorities, because there shouldn't be that much noise, and those parts of the spectrum are probably not allowed to be used at power levels enough to affect shielded copper.
