PC for openwrt

Hello guys the router provided by my isp is just crap,they don't let me access to it configuration and i susppect that there are ppl not from my famly or friends ussing my internet so i want to build/buy/use a computer with openwrt to be my home router and make the isp router just bridge, so the question is: wich spects should have the computer to be the router for a family of 5? Btw i hope to install some add blocker in the Will be openwrt router.

Thanks in advance to your guidance :grin:

Plenty of options. If Wifi is needed in the same device you can't go wrong with OpenWrt One if you can get your hands on one. The GL.iNet GL-MT6000 is another good option with excellent support. If you just want a router/firewall, many x86/64 Mini PCs or Raspberry Pi 4 or 5 are good choices as well.

Thanks bro i ill check the specs of those and see what i can do ! Im from argentina so i need to build it myself or buy some cheap lap and start bing creative cuz the economy does not help, the salary is low and stuff expensive here :sweat_smile::sweat_smile::sweat_smile:

If you cannot access your gateway, to set a password only your family knows, how are you going to put it in bridge mode?

Well bro i take the router phisicaly to the isp so they work on it and then they give me it back, if you think that thi is retrograde and backwards well yes and they are the only ones who operate in this way here, but also is the only company who provide optic fiber in my area :man_shrugging:

Btw about the last quote: last sunday some one just conected screen mirroring from his Phone to my kitchen's tv and was not from my family

If you have the parts laying around then you can build one for nothing.

If you have everything you need except a second nic, you are getting into cheap consumer router range.
If you need to buy much more (e.g. WiFi AP, switch etc) than the parts you already have, you can build a very robust system but not a very cheap system.

For a router, like for other devices running 24/7, power efficiency is the major requirement. x86_64 can be pretty power-efficient here (idle power consumptions figures between 4.5-11 watts are very well achievable), but usually not with existing hand-me-down components from your old gaming rig. You typically will have to carefully select the right PSU, mainboard and other components to achieve low-power and quiet operations, this usually pays off on your electricity bill.

What x86_64 cannot do properly/ easily, is acting as AP.

I was checking what darksky has recomended me but the mt-6000 costs more than an x64 mini pc, at least here, i was thinking in buying/repurposing some old lap (to save in electricity) if posible with a gigabit ethernet, buying another usb gigabit ethernet adapter, a gigabit switch and to emit wifi some wifi dual band extensor (one of those that can be conected by ethernet) i dunno how potent ( micro and ram) that pc must be to run openwrt smoothly at home and how viable my idea actualy is

Yessss your absolutly right about power consumition!
I was thinking in one of those Intel like atom or celeron that almost you dont even need active disipation, but i dunno how much ram and how much muscle i need to run openwrt properly at home ( and with an add blocker if posible) i got like 10 or 15 devices but nothing doing heavy up/down-loads just some phones, tvs and ip cams (not 4k) and not all running at the same time almost never

Alderlake-n n100/ n97 should do for anything 'routerish' up to its capacity of four 2.5 GBit/s ports. For RAM around 1 GB would already be luxurious, as SSD anything with 1 GB or more should be fine. That doesn't mean you take out the scissors and cut RAM/ SSD into pieces, nor to get the lowest-end option at all costs, but these are not defining factors for OpenWrt - so just find the sweet spot in terms of pricing vs specs.
Do resist the urge to overload this device with non-core-routing tasks, just because it has cycles/ SSD/ RAM to spare, it's your border gateway, keep its attack surface small and reduce the risk for misconfiguration.

My old/ second hand Atom j1900 (do not go older than this, power efficiency was noticably worse before, as was performance - and baytrail-d has design inherent stability issues) system needs around 40 MB SSD space and barely more than 140 MB RAM, it can route at maximum capacity of its 1 GBit/s ports, but not quite with sqm/cake (~800 MBit/s, as I only need it to do half of that, it's fine for me). So that's what a decade old Atom can do, an also a decade old ivy-bridge celeron 1037u doesn't even wake up for doing sqm/cake at full 1 GBit/s. Alderlake-n n100/ n97 should cope with 2.5 GBit/s comfortably - at around 6 watts idle.

Any atom quad with like 2gb ram or similar it is inoff then if im not miss reading <3 many thanks bro!

Edit: btw will be inoff to also install the add block in openwrt? It is the only thing i wanna have "extra" cuz my tvs are samsung and with that crappy OS im forced to use the native YT app😅
