My Intel laptop can connect to the router at 300MB, it has Atheros chipset it seems. My ASUS wireless router, with DD-WRT firmware and configured as a wireless client bridge can also connect to the router at 300MB, it has a Broadcom chipset.

QUOTE(aliex87 @ Apr 3 2012, 05:47 PM) hi all sifus here, i have a question. i just got a RB750. i want to setup it to be a router at my school's computer lab. now my school use maxis's vsat, which which are connected to a 24 ports switch. now every computer need to configure ip address before can connect to internet. now i want to make the rb750 to be a dhcp server, that'll give automatic ip to all pc connected to it. my setup will be vsat gateway => rb750 => 24ports switch =>pcs/ap/wireless routers. how to setup it? ive looked in the wiki and cant seem to find the answer.....i didnt know that mikrotik is very hard to configure...i bought it because my friend said its high quality......hope any sifu can point me to the right direction...tq.. How did the Maxis vsat device works? Is that a router by itself?  Assuming that the answer is yes, and that the Maxis STB has its own IP (for example 192.168.1.1). Connect the decoder to port 1 of the RB750. Connect the 24-port switch (I assume it is unmanaged) to port 2 of RB750. Configure the port 1 of RB750 to have the IP of 192.168.1.2/24. Make a srcnat masquerade NAT rule with port 1 being the Output Interface. Create a DHCP server running on port 2 of RB750. If the said port is part of a bridge, run the DHCP server on the bridge. If a bridge exist, port 1 must not be part of it. Configure the computers to use DHCP, and then connect them to the unmanaged switch. At this time, the computers should be able to connect to the Internet already. |

QUOTE(aliex87 @ Apr 3 2012, 07:08 PM) thank you for replying in the first place Ok then, as of now, how did you configure static IP for a computer that will connect to the Internet via the STB? the maxis vsat stb has static ip range (10.193.10.200-250) (i have no way to set it to be dhcp enabled) so in a common router i'll have to set the wan to one of the static ip in the range. so here i have to 1. configure the port 1 of rb750 to have the ip in the range of (10.193.10.200-250)? what is the /24 suppose to mean? how to make a srcnat masquerade nat rule with port 1 being the output interface? very sorry im extremely noob in this, hope you will be patient with me...  IP Address: Subnet Mask: Default Gateway: Fill the info above, and we can go from there. |

QUOTE(aliex87 @ Apr 4 2012, 12:40 PM) IP Address: 10.121.192.205 The default gateway isn't even in the same /26 subnet as the example IP address is. Plus, it isn't what you have said earlier, where you claim that the Maxis STB used static IP addresses between 10.193.10.200-250.Subnet Mask: 255.255.255.192 Default Gateway: 10.121.194.193 can you help me? A question, if you configure the computer this setting:- IP Address: 10.121.194.205 Subnet Mask: 255.255.255.192 Default Gateway: 10.121.194.193 can the computer connects to the Internet? |

QUOTE(aliex87 @ Apr 4 2012, 01:37 PM) sorry, the 10.193.10.200-250. i mention earlier is wrong, i confused with the schoolnet adsl modem setting. the one i posted above is the maxis vsat setting. So the setting I mentioned works then? If yes, below is what you should do.here' a screen shot: other computer has 10.121.194.194 up to 215 that i have seen. there's one wireless router been assigned 208 by me and its working. internet is slow but working, help me here Connect the decoder to port 1 of the RB750. Connect the 24-port switch (I assume it is unmanaged) to port 2 of RB750. Configure the port 1 of RB750 to have the IP of 10.121.194.205/32, and the network to use 10.121.194.193. Make a srcnat masquerade NAT rule with port 1 being the Output Interface. Make a new static route entry where the destination address is 0.0.0.0/0, gateway being 10.121.194.193, and the distance being 1. Create a DHCP server running on port 2 of RB750. If the said port is part of a bridge, run the DHCP server on the bridge. If a bridge exist, port 1 must not be part of it. Configure the computers to use DHCP, and then connect them to the unmanaged switch. After that, from one of the computers, try pinging 8.8.8.8 This post has been edited by asellus: Apr 4 2012, 02:00 PM |

Step 3 is done at IP -> Addresses.
Step 4 is done at IP -> Firewall, in the NAT tab. Step 5 is done at IP -> Routes. Step 6 is done at IP -> DHCP Server. In Winbox, click the 'New Terminal' button, run the command '/interface print' and put them here. |

QUOTE(Prince of Andalus @ Apr 19 2012, 08:59 AM) anybody can help in mikrotik forum? Put output of '/interface vlan print' here.i'm just stuck in configuring intervlan routing in mikrotik.. http://forum.mikrotik.com/viewtopic.php?f=2&t=61219 Hi everyone, I just got 1 RB750UP to play with. I'm trying to configurre intervlan routing in this model but not fully functional. This my diagram.  User A - can ping 8.8.8.8 (internet) - can ping 192.168.0.254 (ADSL internal interface) - can ping 10.0.0.1 (br-vlan2) - can not ping user B (10.0.0.200) User B - can not ping 8.8.8.8 (internet) - can not ping 192.168.0.254 (ADSL internal interface) - can ping 192.168.0.1 (br-vlan1) - can ping user A (192.168.0.200) 1. How do i make user A can ping user B (10.0.0.200)? 2. How do i make user B can ping 192.168.0.254 (ADSL internal interface) and the internet through that? TQ very much for your help. A question - why you don't put the ADSL router at ether-gateway interface? You are lucky that the ADSL router and vlan1 is in the same broadcast domain, else User A will not be able to connect to the Internet. |

QUOTE(88sales88 @ Apr 25 2012, 07:49 AM) Isn't there anyway to configure the rb to function as a normal wifi client to the remote ap ? The answer to the first question is yes, but then you cannot use the RB751G as an AP then. If the remote AP supports WDS then it is doable.Or is the challenge because I want the rb to also serve as an ap to my PC clients wirelessly? |

QUOTE(clawhammer @ May 18 2012, 02:58 PM) kaisam, thanks for all the help earlier and I know you're an expert in this Doesn't that will limit the bandwidth on the wireless network, which is a strange thing to do? May I ask a question? If I want to limit bandwidth for all my wireless connections, what do I need to do? I suppose I first need to create a queue and assign it to my WLAN then limit the bandwidth from there? Anything else?If you want to limit Internet speed for wireless users, detach the wireless interface from the bridge, run a DHCP server on the wireless interface with its own IP range, and then throttle the said IP range Internet speed. |

QUOTE(clawhammer @ May 18 2012, 04:10 PM) Maybe I should explain further as to what I'm trying to achieve Then what I have said before will do exactly what you want. All devices that connect to the wireless interface of the router can have its Internet connection throttled to whatever speed you wanted, while keeping the LAN users to enjoy full speed Internet access. Your earlier method will not only limit Internet speed but also wireless LAN badnwidth. I have a lot of wireless devices but my PC is running on LAN cable. Sometimes my family members which connects to wireless would YouTube, upload/download, etc which takes up a lot of bandwidth and eventually it affects my online gaming experience. What I want to do is to limit the bandwidth available to these devices so I thought it's easier to limit by interface rather than MAC or IP address?If you have a better solution, please let me know. I'm sorry as I'm not a networking guy and the other day it took me so many hours just to configure port forwarding on the router, lol. |

QUOTE(clawhammer @ May 21 2012, 03:23 PM) Thank you sir but I have no idea where to start, lol. I suppose the WLAN is already a separate interface for now (default configuration) so I basically need to create an IP address range and assign it to this interface then a queue to throttle it? With your router, I'm sure that the wireless interface is part of a bridge, therefore you cannot run a DHCP server on the wireless interface if you already have another running on the bridge. Detach the wireless interface from the bridge, assign a new IP address in a /24 range that is different than the one used by the bridge, run a DHCP server using the said range (no need to utilize the whole /24, use a /26 only for example) on the detached wireless interface. Then throttle the DHCP range they way you wanted it to happen.The VirtualAP method can be used too though. Make a new virtual AP, assign a /24 address range to it, run a DHCP server to distribute address from a /26 within the /24, then throttle away. |

Because Mikrotik routers are enterprise-grade product and is also affordable (at least compared to the likes of Cisco anyway).
