Hi,
My name is Diyar I work as IT for a company and recently I started to use mikrotik products for the network and I am happy with the features of mikrotik, but sometimes I face some issues I can not find a solution for it and I hope that you help me with it.
My problem is that I have a routerboard and 4 caps connected to it by on by Capsman feature, everything is fine and working great but when I connected the network printers on the network and I tried to use the network printer scanner the scanning was very slow. I checked every thing but I did not find a problem I have 4 network printers when I try to use it or to scan sometimes it is very slow and sometimes even not working I checked mikrotik forums for solutions but I could not find a solution so please if any one can help me I will be very thankfull.
Note: I enabled the client to client forwarding from first time that I enabled the capsman.
No reply till now?!
I have several access points within CAPsMAN and 3 Wi-Fi connected printers with network scanner feature (pair of Canon MF217w and Canon MF237w).
First of all you should know what access point your printer is connected to.
Sometime I had issue (for example after rebooting access points according to mains failure) that printer connects not to nearest AP (that is still in booting process) but to some far AP (that is started already). In this situation CAPsMAN registration table could show weak Rx Signal worse than -80. As a result, printer could print, but scanning took very long time or impossible at all.
The simple solution was to reboot printer. Because of all APs are ready, after reboot printer connects to its “native” (nearest) AP and scanning is good again.
If this will not help you, next step is to run Bandwidth Test from AP to BTest Server at router with CAPsMAN
As I mentioned in my problem post I am using Capsman and in the registration list I can see that the printer is connected to the nearest cap, it is not that not connected or far it is just when scanning taking to long time I tried with all kind of printers new and old all the same plese any help ?!
What Rx signal of your printer do you see in registration table?
Make bandwidth test between cap and router with CAPsMAN. If you are not similar with this test:
- Run bandwidth server at router with capsman (Tools → BTest Server). Enabled it and uncheck “Authenticate” for simple use.
- Begin bandwidth test from the cap (Tools → Bandwidth Test). Set capsman router’s IP to “Test to”. Make several tests with UDP and TCP protocol, make test with different “Direction” (send and receive)
Watch if the test is stable during period more than 5-10 minutes.
Hi vitaly2016,
Thanks for reply, concerning the RX signal in the Capsman the printer signal is 58Mbps and we I do the scaning is reaching 158Mbps.
I did the Bandwifth test and I did not see any failure the signal was stable and I test it from the Capsman to the Cap and from Cap to the Capsman and at all situation the signal was above 90Mbps sometimes reaching 97Mbps.
I do not know where is the problem please help because I fedup with this problem I changed al printers to USB connection.
Hi vital
Sorry for the wrong info, I wanted to write that the RX signal of the printer is -55 and TX rate is about 58Mbps. Regards.a
According to your info I don’t think that problem is in Wi-Fi connection itself.
What is the printer model you use? Do you use native scanner software?
Did you test scanner feature when printer is connected by wired LAN, not Wi-Fi?
As I reported earlier, we use several Wi-Fi connected Canon printers and scanner feature is working good for us.
And concerning possible wireless issue:
How many wireless clients register at you cap when scanning issue occurs?
Maybe some other wireless clients are getting almost all bandwidth?
Is there scanning problem when only printer is connected to cap?
What exactly do you expect out of wireless connection? USB 2,0 goes up to 480Mb/sec, while wireless even under AC speeds cant realistically top that.
If you are looking at rates like that (158Mbps. during scan), you must know that real life you will only get half actual speed than that.
So if you compare around max 100mb/sec over wireless vs 480mb/sec you get over USB there is your speed difference…
Hi vitaly,
I am not comparing USB to wireless, as I mentioned I cancelled all the wireless printers because was not working and I am using USB now the printrrs RX signals shows -55 and the rate is 65Mbps and still not scanning it scan quarter of the pages and then jams all the printers doing that specially when scanning.
What is the mode of printer/scanner ? B ? G? N ?
If you have any device with B standard then AP needs to talk with it and slows G and N modes to B standard.
If you can switch printer/scanner to do it. If you can configure AP/CAPSMAN not to use only G nor N nor G/N … do it to avoid slow B modes.
Read this: http://searchmobilecomputing.techtarget.com/tip/B-vs-G-Understanding-mixed-WLAN-performance
Unlikely to be B or G if it’s connected at 58Mbps.
Can u test without capsman?
Can u test with local forwarding mode?
