--- Quote from: Halcyon on February 07, 2023, 07:36:26 am ---I just bought a TP-Link VDSL2 modem/router/wireless AP for a mate to replace his failing one and it's pure junk. It actually forces you to download an app and sign up for an account just to configure it. No settings in the web GUI at all (although it actually has a HTTP server and web interface for stats). It literally took me an hour to set up because of that garbage. The app kept throwing me out and I'd have to factory reset and start all over again, for no reason at all. Shit like this seems to be a common theme, not just with TP-Link.

Why was an individual buying a VDSL2 modem? They are normally supplied by the ISP. ISPs are the market for these products, The suppliers do what the ISPs want. The ISPs want remote management.

In Australia, you can get a modem/router from your ISP (usually for free) if you choose to, but you can also BYO equipment. You can walk into any office supply store or technology store and buy them off the shelf, without any ISP branding or custom firmware. Quite often the ones the ISP supplies are extremely basic. Just enough to get you an internet connection, some kind of Wifi and VoIP. We don't lock our connections down to use specific modems or lock customers out of theirs (even if it was supplied by the ISP).
His router that was supplied years ago by his ISP was very old and was starting to fail. The Wifi became extremely unreliable and after a few clients connected, it became unstable. It was time for an upgrade.
Personally, I use a Netgate appliance running pfSense. From the street, the fibre goes into an NTD which converts it over to copper ethernet, then from there straight into the WAN port of my router for me to do whatever I want with. All the authentication/DHCP etc... is done on my own equipment.

A modem is a modem. It basically either works or it doesn't, and a lot of them are unreliable enough I'd rather the ISP bore the cost of replacement. ISPs usually supply an integrated modem, router and wifi box these days. The non-modem features in those can be basic. However, you can disable the non-modem functions, and provide your own wifi router to connect to the ISP provided modem.

With VDSL2 connections (as are used here in some areas), it can get a little tricky. Some modems result in faster sync rates than others and may or may not support features like Save Our Showtime (SOS) and Robust Overhead Channel (ROC), which are also used here to maintain sync on poor quality lines.

Thank god, kere they started to offer a nice media converter for VDSL, they offer ZYXEL VMG4005-B50A without Zyxel logo and call it just "Terminator"
I was at first thinking about buying it, but it cost like 1.5€/mont to rent, so it does not make much sense to buy it at this price
I am a little nervous that I cannot look at things like signals and so, but it is the same with fiber, you have just your PPPoE parameters to connect
and it just works

I don't think Fluke engineers spent a lot of time designing thier SV225 'Stray Voltage Adapter'... Probably less than $10 BOM (1 3K resistor + 2 PTCs in a plastic case) and retailing for $99.
My meter lacks the LoZ feature, which has recently proved confusing while working on some house mains lighting circuits... This would be a great adapter to have on hand, but for that price I decided to just add a 2nd meter to my bench and bought Dave's BM235 which includes the feature.
Probably a really easy build, but without knowing the exact parts I'd rather not experiment with the probes in my hands to find out!

I was looking for some ad9201 a2d converters.
£15 + VAT at RS and similar sites.
Looked on Ali Express and they were £1.50 each.
Worked ok too.
PC graphics cards are silly money. The to pend ones while fast seem to waste a lot of energy in heat.
I dont have a graphics card in my pc I just use IGPU.
Plays games ok and does PCBCAD so I am happy with that.
