Extremely slow wireless on SG-2440



  • Recently purchased a SG-2440 from the pfSense store.

    Configured Wireless network as its own subnet and enabled DHCP server for the subnet.

    Problem is that wireless throughput is extremely slow. e.g. Google.com takes over a full minute to load.

    What's going on?

    Are you using wireless in the SG, or an external AP?

    that sort of speed seems horrific even if you were on B speeds..



  • I'm using the internal wireless (it's an official pfSense store unit), set to 802.11ng only.

    so I take it google when wired is fast, so what is a speedtest show wired vs wireless?

    Are you using dns forwarding or resolver?

    Yes, wired is expected speed.

    Did eventually get wireless working at normal speed, but the signal is very weak. So weak it doesn't even reach where my old Linksys WRT54G does.



  • Have you tried using pfSense wireless in 802.11NA mode. The 2.4 ghz band is quite crowded and you really need to jump to 5ghz/NA mode to see good results in most urban areas….
    Do a site survey with Netstumbler and find the frequency holes and use that frequency. I have no competing 5ghz in my area...So I choose somewhere in the middle around 5600mhz

    • No TKIP or mixed a/b/g/n WiFi
      set it to a or b or g or n only please
    • Usage AES-CCM/CMP (enterprise)
      would be the best and strongest encryption
    • search in the used WiFI band for other APs or WiFi devices
      would be good to know how is using which band and channel, so you can take a free one
    • take a unique SSID to be sure for that search the bands and see what they are offering
      likes "meandyouaretwo" this would nobody else using.

    What's going on?

    PCI or IRQ errors are there?
    pfSense only with WiFi or is there Squid, Snort and others are in
    the game that are slowing down the entire WLAN throughput?

    I had the exact problem with two sg-2220s. same wifi card as your sg-2440.  I believe something is not right in the driver or setting. The wifi is not slow at all time but some time fast some time slow. There is some signification amount of "out errors". "in errors" is ok however. Have you found a solution yet?

    I used AES and ng only. Tried either 5G or 2.4G, both has same issue. I had picked the clear channel and test the speed on exact same spot every time. No other package is running. Wireless is hard to troubleshoot. Any other suggestion? Well. May be I should just forget it and buy a access point.

    "May be I should just forget it and buy a access point."

    Give the man a cookie..  If you want decent wifi, then you more than likely need multiple AP properly placed to cover the area you want to cover…  The router is almost never in the best place for wifi coverage.. I really don't even understand why people attempt to do it.

    Let pfsense do what its good at doing routing/firewall your traffic.  Its not a Switch, its not an AP.. its a routing firewall..

    No cookie, this is not a helpful reply. When purchasing a pre-configured router/firewall/ap combo directly from the pfSense store that advertises a/b/g/n wireless capabilities, and costs upwards of $500 USD it is not unreasonable at all to expect it to "just work."

    Especially coverage in a 1,400 sq ft house…any crappy Linksys can (and currently does) do that. Instead of being condescending and assuming you know the configuration and environment, try seeking to understand before commenting.

    Yeah, so get that crappy Linksys. It's made for WiFi. Seriously, all the wifi crap should be nuked from pfSense code. FreeBSD is NOT usable for WiFi, end of story.

    Looking at the store item for the 2440 https://store.pfsense.org/SG-2440/

    I don't see mention of any sort of wifi features, it lists that you can get a wifi card as an "option"  but I see no claims to its performance or that it even supports N.. Just that the optional card your purchasing is a/b/g/n and 2T2R

    it also has usb ports - do you think you can connect a usb printer or disk/stick and use it a print server/nas ??

    Even when you click on the more features of pfsense in that listing it really makes no mention of wifi supported, or claims to performance of wifi.  If you would of looked over the forums you will see that wifi is not a selling point of pfsense, if you look at the freebsd that its based up you would also see as dok points out wifi not a strong point in freebsd.

    Not sure why you would think that wifi is a strong point here…  It has been, and prob always will be some "option" that you may get to perform ok in a pinch.  But to be honest anyone looking to spend $500 on a router/firewall - not sure why this network would have a crappy wifi card in their router/firewall as their wifi for their whole network, etc..  The only real use I could see for a wifi connection would be out of band access to pfsense itself, as a possible wan backup link, etc..

    I agree you get no cookie for not doing some basic research before dropping $500 to what the good and bads of the device were.. I doubt you will find any post/article or anything anywhere stating the wonders of pfsense wifi support.  But a simple breeze over of the forums will find lots of caveats to its use, and limited devices and speeds supported.

    here for example... https://doc.pfsense.org/index.php/Is_802.11n_wireless_supported while it does say 2.2 and freebsd10.1 which does have 802.11n support in general, but support may still vary by card and driver.  Not sure I would take that as hey you can run your locations wifi off this thing ;)  And your speeds are going to rock ;)

    I am with dok here they should prob just remove the functionality all together, and make it clear on their documentation you should run external AP for your wifi..

    Could it be that the miniPCIe card was glitch out of this miniPCIe slot a bit and now you get it not solved out.



  • @doktornotor:

    Nope.

    It is not unreasonable to expect an enterprise product sold with an officially offered wireless add-in card to, you know, work with wireless. Shocking concept.

    Your opinion of what belongs in a software distribution notwithstanding, reality is that pfSense has an entire GUI page dedicated to wireless configuration, official documentation on wireless, and an official list of supported wireless hardware. I emphasize the word supported.

    So, thanks for the worthless reply, but until wireless support is removed from the distribution, I'll continue to assume it's supported.

    @johnpoz:

    Sure, I can understand that. But if it's not "really" supported it should be removed altogether, and not expected of the customer to "just know" because it's "not emphasized."



  • It is not unreasonable to expect an enterprise product sold with an officially offered wireless add-in card to, you know, work with wireless. Shocking concept.

    But what is then your problem? What is not running well then for you? If all is supported and there are also
    DOC´s out about WiFi you could solve it and/or fine tune it right.

    "Problem is that wireless throughput is extremely slow. e.g. Google.com takes over a full minute to load."

    From that there is a so much we can work with and help him troubleshoot..  For starters what mode is client using.. How do you know its not the client side?  Maybe its wifi is fine and dns is a problem..

    I've tested with various clients, including a Lenovo ThinkPad running Mint 17.2, Nexus 5 running latest Android, and an older Mac laptop.

    The signal is extremely weak, to the point that it's odd, e.g. just walking down the hallway about 20 feet (with clear LoS to the router) and the signal drops off immensely.



  • Are the antennas fully connected?

    Could it be that there is another WLAN source that is over lapping your signal, perhaps a stronger one?
    Or on the same channel?

    Are you using AES-ccm or web encryption standard?
    Are the antennas internal right connected?
    Are you using TKIP or on standard only?


  • LAYER 8 Global Moderator

    Well vs saying strong and weak signals.. What are the actual numbers? You mention linux, how about simple iwscanner output.. What is the actual signal strength?  What channel are you using, does this happen both at 2.4 and 5ghz?  Are you using using 20mhz or 40?
