Need help getting pfsense to work properly



  • Hi all. I've build 3 pfsense routers 2 couldn't run pfsense and the third works fine. After 2 months of try i managed to get internet to work but i have one problem which i can't solve and i need your help. I have a cheap 2usd router laying around and using that i get 75mbps download speed while on pfsense it is hardlocked at 20mbps. I have no idea what to check or look. I checked and i get 0/0 errors in/out.
    Any kind of help appreciated.
    Edit: CPU usage never goes higher than 2%



  • What Nics are you using?



  • Two realtek they can be considered noname, however i did test another NICs and got the exact same results. In theory they both run at 100baseTx Full duplex, if that means anything useful.
    Please tell me what information should i share so this problem can be diagnosed easyly? thanks



  • 100baseTx

    your Nics are not gigabit or your switch/cable might not be gig, you should get 1000 but anyway you do not need gigabit for 75mbps



  • My internet connection is about 75-80 mbps and the NICs as well as the cables are 100mbps. I never said anything about gigabit, anyways where should i start looking for the problem?



  • " I never said anything about gigabit"

    Just wanted to point out to you thats why you are seeing 100 cos your gear is not gig.

    what is your setup like?  whats your hardware? try plugging in the PC directly to pfsense LAN eliminating switch and cabling



  • OKay so, this is how my setup looks like: INTERNET -> pfsense -> laptop(using LAN)
    No switch or gateway or bridge or anything used.



  • is your modem bridged? are you getting a external IP in pfsense wan ? not a internal ip such as 192.168.x.x and what hardware are you using to run pfsense?



  • As i mentioned before no bridge used. I have an username and a password; and the connection is pppoE.



  • The hardware:
    Mobo: MSI using G31 chipset (https://www.msi.com/Motherboard/G31TMP21#hero-overview)
    CPU: E8500 (https://ark.intel.com/products/33911/Intel-Core2-Duo-Processor-E8500-6M-Cache-3_16-GHz-1333-MHz-FSB)
    RAM: 1*2gb 800mhz Kingston
    HDD: 80gb IDE hdd 7.2k rpm



  • You should bridge it. what is the lan IP you given  to pfsense ?



  • 192.168.1.1/24



  • and whats the ip you are getting from your modem to pfsense wan?



  • I can't tell you that, but starts with 85 or 89 if i remember correctly.



  • if your modem is not bridged you  should be getting a internal IP like 192.168.x.x  on wan  so if you are getting external ip your modem is bridged.



  • hmmm… man learns every day, thanks for the info. is that good or bad news?



  • What should i do now?



  • try turning off the modem and pfsense for a while maybe you got multiple IPs queued from your ISP or try Intel nics



  • The modem can't be turned off because it is outside extremely high and gets power from the street. I tryed again today and same behaviour. Any tips left? I tryed disabling some driver features then enabling them they had 0 impact on performance… CPU usage is still between 1 and 3 percentage.



  • At this point im giving up and calling pfsense is still in beta access. Barely works and full with bugs which can't be fixed…
    It is quite sad that an 3usd cheap router outperforms pfsense...



  • Today i gave a try to 2.4 but seems same… Download speeds locked at 2mb/s and whatever i do i can't exceed 3% cpu usage...
    I started using steam for testing speeds because speedtest.net started giving me download test error messages.
    If anyone could help me, i would greatly appreciate it...



  • Just got a bootloop when i tryed to reboot the pfsense… So back to 2.3 but this time i'll try to use the 32bit version.



  • Okay, same behaviour with 32bit version… download speeds locked at 2mb/s and cpu usage locked at 3%...
    I think the only thing left is to sell the hardware...



  • Don't know why YOU are locked on the fact that the CPU only uses 3 %.
    Look at mine : https://www.test-domaine.fr/munin/brit-hotel-fumel.net/pfsense.brit-hotel-fumel.net/processes.html - the green part (approx. 3 %) is the same and everything works fine - ISP gives me about 25 Mbit, and that comes through.

    Don't tell us you have problems, tell about the problem, describe it. Copy past settings, screen, your findings.

    Don't tell us that you can't find your IP "Internet", that's like saying that you driving a car, but are not aware that some where i the same car an engin must be running …

    Check out other forum threads about how to question and ask so feedback can be given that can help you.

    Btw : pfSense 2.3.4 is not buggy, very stable and work great for years now for me



  • Dude it has something to do with your Hardware or setup, look at my results pfsense 2.3.4




  • I tried different NICs, even Intel ones and always the same results: download speed locked at 2mb/s and upload speed is random but between 1.5 and 3.5mb/s.
    While on my 3usd cheap router i get 10.5mb/s download and 5mb/s upload easyly…
    No idea what the problem is...



  • Is that possible that i have to change some buffer sizes or something? Because RAM usage never exceed 7% and CPU usage is hardlocked at 3%.
    The HDD is 80Gb if i remember correctly…
    Maybe i should install windows and test it there too... hmm... i remember using this PC on windows 8.1 64bit and i got correct speeds... so definitelly pfsense issue...

    " I have a cheap 2usd router laying around and using that i get 75mbps download speed while on pfsense it is hardlocked at 20mbp"

    Am I missing something? speeds have changed since your first post.

    You might have some driveR problems, just cos windows plays nice does not mean BSD will, try a different machine



  • I tried… pfSense only runs on this machine, it fails to boot or hangs at bootloader on all 4 other machines i tried...



  • Update: Tried in virtual machine; and i got the same results… donload speed capped at 2mb/s around 20-250mbps/s it deppends... I am clueless...

    Dude this has ZERO to do with pfsense.. You stated your connection is PPPoE right.. Did you contact your ISP about this when you change the device doing the pppoe connection..

    If your cpu was maxing out or something.. Then ok you might say pfsense can't handle the speed, etc.

    When you connect these cheap routers, your setting them up for pppoe - or your just doing dhcp on them?
