Using PC as wireless router

[DesiPower]

I looked around a little bit on the internet and seems like there are some software that can be used on the PC, but what about the hardware?

Can I use any PCI(x) card? or are there some special adapter that can be used to transmit too? Are there any recommended one, maybe with stronger antennas or something?

Can I get a dual band adapter and then have a dual band router? Probably the router software needs to support that?

How does it actually work? I plug my PC to the modem and then the wireless adapter on the PC will transmit like a router?

Do these PC run windows and then a routing software or these routing software are OS in themselves?

I want a strong dual band router, now I can go out and spent anywhere between $150 - $250 or I can get a good adapter and then convert my old PentiumD PC into a router.
Does anyone have experience with DIY routers? are they as reliable stock routers in terms of speed and connecting not getting dropped?

While it is possible I see little point in it, I would look into Unifi access points (or other similar solution) before using a PC. An AP is going to use WAY less power than a full blown PC and be simpler to manage with less points of failure.

That said you can convert a PC into a router using solutions like pfsense, which will give you much more options than the SOHO stuff you can buy. I would still keep the wireless portion separate though. You can think of wireless as adding a switch to get extra ports. There's not really much reason for this to be part of the router.

Any computer with Wireless card can act as an Access Point with free software like this.

A full Router is a different story and all together it does Not worth while doing it.

The electricity spend on it will be after few month more expensive than a new Good Wireless Router.

Non-dedicated, PC based access points are going to be very limited compared to a soho router, and may even be problematic. You'd be better off with a wireless router, and you should be able to find some for much cheaper than $150-$250, even outside the US. If necessary, Amazon ships to Argentina, and there are several dual band wireless routers for under $50.

FWIW, a single dual band PCI adapter will likely cost as much as a router itself.

You have lots of hardware limitations. Most wifi adapters don't have full access point support and none are concurrent dual band, if that matters.

Considering you can get a GOOD 802.11n router for around $50 (TP-Link WDR3600) that is also rather quick as both a router and an access point...why? You'd likely spend more on electricity in a year on your old repurposed computer than you would on the entire router.

Also considering the march of technology, a new 802.11ac router, something like an R7000 might well have MORE processing power than an old PentiumD, and it will certianly use massively less power.
