I have some questions pfsense routers.



  • Ok i am thinking of setting up a pfsense router because i live with my sister and the main router on the other side of the house from my room,and my sister does not want me stringing a cable across the house,and i could just use one wifi adapter on my computer,but i am wanting to hook 3 or more computers in my room,and i only have 2 wifi adapters.

    Question #1 Can i use a USB wifi adapter on a pf sense router to pick up the wifi them using ethernet adapters and cables hooking up the computers to give them internet?

    Question #2 Can you use 2 USB wifi adapters? And will it help any at all,like with bandwith?

    Question #3 Would a old (1.3GHz or might be 1.7ghz idr)with 128mb of ddr ram,and some old 10/100 ethernet adapters be good enough for a pfsense router?



  • Why not just get another USB wifi adapter?
    1. They are dirt cheap.
    2. Overall bandwidth will be higher.
    3. You'll save on the electricity of running an old inefficient computer.

    Until i can get a better job i don't any extra money right,my current job has been cutting everyone's hours,i have been getting 28-33 hours a week,making less than 9 bucks an hour,and i was just going to make this with parts i had lying around.

    Ouch.

    What you are looking for is bridge and not a router/firewall, but yes pfSense should be able to do what you want it to.

    Q1: Yes. Make sure the wifi dongle is compatible with pfSense though.. Also, I think the webconfigurator is the only way to set up wifi WAN.
    Q2: You should be able to do this with bonded NICs. https://doc.pfsense.org/index.php/LAGG_Interfaces
    Q3: Should work. pfSense has a low footprint. As long as it isn't doing anything fancy, this should work.

    Bridges are easy to set up. You may be able to get your machines with whichever OS they are running to bridge the wifi and Ethernet interfaces much more easily. Also, if you need to buy switches/NICs to make this work, I'd suggest you to invest in the wifi NIC instead.

    Don't consider me a pro. I just answered whatever little I knew about pfSense.

    I don't think i will need to buy anything,cause i have 3 old NIC cards,plus the mother board i plan to use for this has 2 NIC ports on it. On top of that i have about a dozen old switches and routers that my uncle gave me packed away in a box.

    128MB is the absolute minimum RAM requirement and it would probably require some tweaking to run in that. 256MB is really the minimum you want, more would be better. If that's the hardware you have maybe consider m0n0wall as an alternative.
    Not sure you can do a LAGG with wifi connections. Even if you could the other end would have to support it and you probably wouldn't get any increase in bandwidth probably less in fact. If the router supports simultaneous dual band you might be able to achieve something with two cards but support for 5GHz wifi in pfSense is almost non existent. Make sure whatever you use supports client mode, many Ralink USB wifi devices run great in access point mode but not as a client. Just get something with a decent antenna and take some time to align it for best signal.
