My college provides internet connectivity using LAN cables I m using my router to access wirelessly but my router is interfering my other people connected to the college shared network. Why is it so and how to resolve it?
Use frequency and choose frequency same both in college router and your router, But what is the need of connecting two home routers wirelessly?

so the setup I've got:
Main Router which receives the internet connection and is my primary WIFI network: 192.168.1.0/24
Secondary Router which I've connected via the following method to create a separate LAN: 10.3.3.0/24. Main Router's LAN port --> Secondary Router's WAN port.
I've got this setup fine and can get internet from the Secondary Router's LAN, no problem.
My question is: Is it normal behavior to be able to ping a device connected to the main router from the secondary router?
I would like to isolate devices on each LAN so that devices connected to the separate LAN's can't communicate and wondering if I'm able to achieve this using 2 consumer grade routers?
Cheers!
This is normal behavior because the secondary router knows that IPs in the 192.168.1.0/24 subnet should be forwarded to its WAN port, so it can access hosts connected to that network.
Sadly, you usually can't create 2 segregated subnets with 2 consumer-grade routers, as these only have 2 network interfaces (one for WAN and one for the built-in switch).
I also do not recommend doing this, as double NAT can have unexpected side effects. If you really want to separate devices on your local network, looking into VLANs is a better way. You can use your existing router but will need a compatible switch.
If your routers support vlan management you should use separate vlans for both subnets. Otherwise you cant devide your networks.
I have two devices, a PC and a RaspberryPi, that are connected to two different routers (one has VPN, one does not), that are connected to the same modem. (See diagram). The two routers are physically separated, so it would be difficult to connect them with a cable.
I am trying to access the RaspberryPi from my PC using SSH to run programs remotely on the Pi, and have the Pi send data that the program scrapes back to my PC for processing.
My question is, is this possible? And if so, how would I be able to implement it?
Thanks
I had this working (prior to my network reconfigure).
What I did was set router A as DHCP server.
Router B was configured as not to hand out IP Addresses.
Connect router A and router B on the LAN side.
All clients went through Router A, unless the devices' IP Settings were changed. I only changed gateway to router B to have the secondary connection.
Recently I have followed this link to setup a wireless router into an access point in my home.
Our current network components are as follows:
Main router (192.168.1.1): a Sercomm router configured by the ISP, with DHCP enabled for address 192.168.1.30 onwards.
AP router (192.168.1.2): a TP-Link WD8970 router on the bridge mode, with WDS turned on (on the same SSID, mode and channel as the main router) and DHCP turned off. However, this AP is configured to broadcast a different SSID to indicate a different storey.
Devices (182.168.1.xx): desktop or mobile clients that could connect to both SSIDs.
(click here for the topology image)
The problem is that:
Most of the time, devices connected to AP router's SSID is given 169.254.x.x IP addresses and could not reach the internet
Devices that is configured with a dynamic IP and connected to the main router's SSID could reach only devices connected to the main router's SSID
Devices that is configured with a static IP and connected to AP router's SSID could reach both routers (the main router at 192.168.1.1 and the AP router at 192.168.1.2, respectively)
DHCP packets are not forwarded from the main router (192.168.1.1) to the AP router (192.168.1.2), while other types of packets could flow through
How would you advice on configuring this home network differently, to make it more stable and usable?
I had the same issues in past days. I fixed checking the flag "DHCP RELAY". As soon as I checked it all went fine. All devices connected to the wireless router have received the IP address form DHCP server.
https://www.tp-link.com/us/support/faq/1630/ (the real configuration page on Archer D7 is slightly different form what stated in the link).
This was my network: I have a small usb powered 4G modem/router connected to internet. I wanted to share the internet with several devices located far from the 4G modem/router, so I decided to extend the coverage by means a TP-LINK Archer D7 ADSL modem/router used as Wifi access point. I connected the 4G modem to AP through WDS. The pc's and printers connected to Archer D7 (AP) were fine, security camera, smartphones etc.. no IP from DHCP. After the setting DHCP RELAY everything went fine.
Most of the time, devices connected to AP router's SSID is given 169.254.x.x IP addresses and could not reach the internet
This issue has to do with the WDS connection and poor connection from the AP to the main router. As a wifi expert (ok, expired CWNA) it's never a good idea to use WiFi extenders or WDS in your case. It increases interference, adds an extra hope, and rarely helps. While it's easy to think of these as a signal booster the wifi network protocol isn't setup for these types of connections. Only some commercial APs with parabolic antennas can truly benefit from wifi extenders.
Test with a cable connected from the main router to the AP and use the interfaces instead of wifi. It's possible you have DHCP issues with your wifi issue so first test with static IPs.
If this works then you should leave the cable in place. Understandably this isn't always possible so replacing your main router with a quality wifi router would be my 2nd choice. Sorry I don't know any good consumer grade APs but they are out there.
Just in advance im sorry for my limited expertise with networking, i know the basics tho...
So the issue i have which i am hoping someone can shed some light on..
I want to have 2 routers, each with either own vlan, and i want one router to be able to talk the other but not vise versa,
So my Main router (192.168.1.1) is connected to the modem,
I want to get a second router and connect it to my main router,
The second router i want to have its own vlan (192.168.2.1)
Now that part is pretty easy, here is where i am in over my head
I want the computers on my Main router, to be able to access the ones on the second router... like ping, RDP, ETC
BUT - i dont want the computers on the second router to have access to the ones on the main router.....
Is this possible?
Thank you,
If you are using home routers the key is in the WAN interface.
All the hosts connected in the LAN ports can access the hosts in the WAN port, but not viceversa. Your border router act this way: if you want a hosts communicate directly from WAN to LAN you have to forward a port. For example, if you have DVR with cameras and you want to monitor them from Internet, you will have to forward the ports the DVR uses.
So, you could connect in the 192.168.2.1 subnet (just to clarify, this is not a VLAN, this is a subnet, or you can also call it just a net, VLANs are another thing) the PCs that you don´t want to be accessed from the other hosts.
VLANs are kind of partition of a LAN where the broadcast can propagate inside it but cannot go out. They are used for security, performance and easy of administration. They belong to the 2nd. layer of the OSI model.
The final topology in your case is as follows:
Let´s separate your computers in two groups: group A are the ones you don´t anyone has access and group B are the ones you want to be accessed from another PCs.
First you have your modem connected to the router that will act as border router. It´s LAN IP will be 192.168.1.1/24 (/24 is a notation for the subnet mask 255.255.255.0).
To that router you will connect to it´s LAN ports the group B PCs with IPs ranging from 192.168.1.2 to 192.168.1.254 (.0 is reserved, .1 is you border router and .255 is also reserved).
Also to that router you will connect the second router to its WAN port. In the second router you will set an static IP in its WAN port that belongs to the subnet of the border router. For example 192.168.1.2.
The second router LAN IP will be 192.168.2.1/24. Finally, you will connect the group A PCs to the second router LAN ports. With IPs from 192.168.2.2 to 192.168.2.254. This will be the more "protected" LAN.
I hope this could help!
I have setup AirPrint via CUPS in Ubuntu 12.04.03. This works through my main router, when my iPad and iPod are on this wifi router. That router is the main ADSL into the house. I then have another router, a MikroTik Routerboard, on an Ethernet cable attached to this. I use both of these networks for different iDevices, however the CUPS server is attached to the main router.
I think AirPrint only works on the local router, but I need to use it on both networks.
Is it possible to create some sort of tunnel to direct the AirPrint into the MikroTik router's network?
Thank you.
AirPrint utilizes the Bonjour service to discover local 'Airprint' printers. Because Bonjour can 'only' discover local printers it makes it almost impossible to reach outside your local network to discover nearby printers.
The best advice I can give would be to purchase a second network adapter (Ethernet or Wireless) and connect it directly to your 2nd 'MikroTik' router. This would then allow you to have the AirPrint server accessible in both networks. An under $20 fix to a complex solution.
The easiest solution however would be to use your second router as a bridge to your main network. However I am guessing you're avoiding this scenario for some undisclosed reason.
