I have routerOS v5.6 level 5 with hotspot. when many users login (20-30 users) to the hotspot, the internet is very slow. I have two 12Mbps ADSL lines and each user has 800kbps Internet speed. I have the hotspot on intel PC and I am using RB450 to combine the two lines using pcc code from this site.
when there is few users, the internet is very fast. I don't know how to fix this problem.
Re: Internet is slow when many users login
When you say ADSL you are implying two things;
Low upload capacity and if you reach close to the maximum upload capacity it will indirectly affect your download speed.
ADSL modems usually have very small CPU's that can't handle too many packets per second.

Shouldn't the modem handle the speed of 12mbps. The modem see the use as big download from one userWhen you say ADSL you are implying two things;

Re: Internet is slow when many users login
If i was you, I would question my assumptions.
Perhaps you could consult someone who can debug it locally?

Re: Internet is slow when many users login
No, each users opens many connections. The more users the more connections. Since the modems have to keep track of all these connections and it has limited memory and cpu it has a limit to how many it can handle. It depends a bit on the modems though. Some modern modems are much better in this than old ones or the cheapest you can get.Shouldn't the modem handle the speed of 12mbps.

Apart from that, 20-30 800kbps users active (with traffic!) is a bit much for 2 x 12Mb adsl lines.
This for two reasons:
1. 12Mb adsl hardly ever means you get 12Mb. Usually only 80 to 60% of that.
2. More important, and in line to what ´sten´ already wrote, even on plain download, a user produces upload traffic. So, although the download might not even be saturated, for that traffic the upload already might be! And that will have a direct slowing effect on the download....
One other important item not mentioned. Do you do QoS?
If not, it takes only one P2P user to bring a complete adsl line down by consuming all the upload.
So setup a proper QoS system.
Re: Internet is slow when many users login
upload also devide. Each user has 800kbps download and 50kbps upload. Each ADSL lines has 12Mbps download (most of the time is 10Mbps) and 1Mbps upload (reach 800-900kbps).No, each users opens many connections. The more users the more connections.

Any way I decide to add a new 12Mbps ADSL line and combine it with the two
Re: Internet is slow when many users login
I would strongly recommend to turn the modems in bridge mode because
of the low CPU an memory modems have (as mentioned above).
And let routerboard do the pppoe connection to the internet.
This way modem acts only as "wire", so will not affect packets flowing through it.

Re: Internet is slow when many users login
I think there is a little mistake on some of your rules where you are marking routes.
You have passthrough=yes. On those rules you need passthrough=no, otherwise the packets
will keep on being processed by the following rules
