Cap Lite RBcAPL-2nD slow wifi speed

Fri Mar 11, 2022 11:17 pm

Hello,
I am having issues with Cap Lite RBcAPL-2nD, set to CAP mode, controlled by CAPSMAN on RB750Gr3. My internet input speed to the RB750Gr3 is 150/10 Mbit. The Cap Lite is connected directly to the RB750Gr3. No matter what frequency or band I use, I never get more then 50Mbit over wifi from the Cap Lite.

Manufacturer says, it should do 300Mbit over wifi. I know it wont in CAP mode since the input is over LAN which is only 100Mbit, but still 50Mbit is much lesser then I would expect. I would be happy with something around 90Mbit.

Any uggestions?

here is RB750Gr3 CAPSMAN config:

You can change channel-width from 20Mhz to 20/40Mhz, that should give a boost to your throughput, but as cAP lite has only a 100Mbps ether port, you won't be getting much more.

That and:
- band selection: use 2Ghz N only if possible for your client devices (it's covered)
- Data rates: increase supported rate to at least 18mbps (if your client devices accept it !! You may have to play a bit to see how far you can go) - I see you have 54Mb as basic and supported rate. It doesn't cause any problems for your client devices ?
- Data rates: supported rates, remove everything lower then 18mbps (see previous remark, both go together)
- disable WPS mode (I don't have the device in front of me but as far as I know Cap Lite does not have such a button, so disable the feature, especially if not being used), it takes away airtime
- scan surrounding frequencies/channels ! See if there is a channel where you can be "alone". Difficult when using 2.4Ghz but maybe some channels are less crowded then others ? Even one single other AP using the same channel, will take down your performance. It's only when you're completely alone that you can get the most out of it. And co-existence (same channels being used) is better then overlap !! (overlap = e.g. one AP with 40Mh on 6, another with 40Mhz on 7)
It could also mean being alone using 20Mhz might be better then using 20/40 when having overlap.
Experiment.
- don't use capsman forwarding unless really needed (ie: change local-forwarding to yes). It requires encryption of part of the communication (headers) and decryption again at the caps controller. Waste of time and resources.

On mAP or mAP Lite (same HW config ?) I can get close to 70 Mbps using these modifications (but there is always one other AP in the neighborhood at home, I'm never alone on whatever channel I use). I'd say that's more then enough for those little buggers on 2.4Ghz.

Where is config of cap lite ? Or is it only cap-mode and nothing else ?

hello, thank for you reply, as you can see in my configuration,
- I use 2GHz-N only
-reagrding data rates, none of my connected clients have problem with 54Mbit
-I tried to disable WPS, but I found this optoin only under CAP LITE wireles settings, and when tried to change, it said its controlled by the CAPSMAN. In CAPSMAN i didnt find this option
-I did scan all channels around me and 2472 was the only one, which wasnt used by any other router, so i am the only one around using this frequency
-I dont use Local forwarding on CAPSMAN
-CAP LITE is iny CAP mode, nothing else, no firewal, no nothing, everything is controlled by the CAPSMAN and still getting maximum of 52Mbits over wifi

Re: Cap Lite RBcAPL-2nD slow wifi speed  [SOLVED]

Mon Mar 14, 2022 3:41 pm

What's this ?
/interface wireless
# managed by CAPsMAN
# channel: 2472/20/gn(18dBm), SSID: MikroTik-99999, CAPsMAN forwarding

You're not using local forwarding ? You should. Unless you have a specific reason not to ?
And set on capsman the bandwidth to 20/40, see what that gives.

Is there a reason why you use capsman ? A lot of devices, perhaps ?
If only a limited number, do the settings on the caps devices directly. Much easier.

eeeh, what yo you mean what is this? this is that the CAP is controlled by the CAPSMAN



-I tried to use local forwarding, but it didnt have any impact on the wifi speed
-the reason is, that i like this option, its at my home, so its only one device, anyway I tried to use CAP LITE as a router, and the results were the very same...

Wifi speed will never be impacted on itself but speed between Cap Lite and Hex WILL be impacted as explained above.

You don't need to use CAP as a router. Just use it as a simple access point.

-I didnt notice any impact on the speeds between capsman and caps if local forwarding enabled/disabled

-yes i meant using it as an AP, same results

So i guess it is not solved...

If you remove the CAP from the Capsman, do you see any improvement in the Speeds ?

oh my, now i did try to put CAP LITE in Home AP mode, Ive dissabled WPS and now Im getting 62,6Mbit over wifi, which is little improvement.....even upload is now 11,8Mbit, which is strange since my internet connection limit is 150/10Mbit :)

As you can see the problem is not the CapsMAN.
Don't expect to reach the full bandwidth of 150 Mbps...
Other than that remove Band b, set Bands to g/n only... Set channel width to 20/40 XX and select a less crowded frequency.
Then test again...
