Could I use this old router for pihole?

Hi! I wanted to know if I could use this old router as Pihole, instead of having to buy a Pi!

No you can't - this thing has likely something like 4 or 8MB of RAM and 16 MB of flash memory.

If you are very lucky, you can install OpenWRT, and then use an Adblock-plugin. But mostly likely waste of time.


  • a Raspberry Pi Zero without Wifi (for 5.50 Euro !, here or here, no I am not affliated with those shops);
  • a power supply;
  • an Ethernet USB dongle; and
  • an 8 or 16GB class 10 SD card.

All together it shouldn't be more than 20 Euro, plus maybe shipping.

Thanks you so much! Would I be able to run NextCloud, for Home Local Cloud, also?

This is a little bit off-topic, and I can only speak for myself, I am sure others have different opinions.

I think, raspberry pis are not a good piece of hardware to run a nextcloud server. They run the server software just fine, but the issue is storage. Pis don't have a decent interface like PCI, SATA, M2, ... yet to connect multiple drives. If you wanted you could attach a USB HDD or two - that would work. But in that case, rather buy a Rpi4 with 8GB of RAM.

There is the Odroid-HC1 and -HC2 (ODROID-HC2 : Home Cloud Two – ODROID), which apparently have a SATA3 port and you can simply attach a 2.5'' or 3.5'' drive. Pihole could easily be installed on that device too.

I may go with the Pi zero and let you know! Thanks again!!

Pi zero is the best if you are on a tight budget. I was actually able to get the one with Wifi for similar price. Someone printed me a 3D case and found some 2GB microSD and MicroUSB charger laying around.

Sorry one last question!
Do I need a monitor or could I do the PiHole thing headless? And then If I wanted to connect to the PI, could I do it with another device?

I just need a Power Adapter, may I use my old Android one! :slight_smile:
For me, the Pi Zero only will cost 10€ With shipping

It should deliver 2.0A @5.0V, or even better 2.5A. Phone chargers usually don’t go above 1A.

No need for a monitor or keyboard. You can do everything using SSH. Check out the guides available on the internet.

Wifi is unreliable and has a high latency. I would not do that. A wired connection is always better.

I’m running a pi zero headless....but apparently ordered the wrong one cause mine didn’t have wireless(zero w h?) built in....luckily the adafruit kit I ordered had a micro usb to usb cable and scrounged up an old linksys WiFi dongle and got it up and running completely headless....

Thanks for pointing that out. Did you measure the latency?
I think I was told once that the difference is not noticeable

I think you can assume a latency of 0.5-2 ms in ethernet, and 20-30ms in wifi. (Wifi latency can be higher, depending on a lot of factors), however, I did not measure it.
