Adding a Second router to my LAN

• Wired or wireless - adding a Second router

  I'm so completely confused and need a little guidance. For these past years, I have been using a LinkSys BEFSR41 EtherFast Cable/DSL router. It was my router reliable wired . I have a few computers in another room (home network), I have connected to the router via a hub 24-port Linksys (EFAH24). The hub died this weekend - the power supply is shot.

  A good friend gave me the WRT160N router so that I could use it as a hub. One of the problems is that I can not enter the configuration for the wireless router screen because it has the same address as the router wired origin.

  Basically, I try to use the mannequin on the wireless router - I rarely, if ever, need wireless; but it was free and a nice Starter unit. So, I try to understand how to use two routers, but use a wireless as a fictional hub. All I'm doing is to restore my previous network topography.

  Any help?

  Your wired router settings remain the same. All you need to configure is the wireless router. To set it up, unplug the network and the only thing to which it is the computer. Here is the procedure. Follow the configuration of the LAN - LAN connection.

• Use the second router to extend the network to Time Capsule

  I have a v7.6.7 running Time Capsule 1 TB and older airport. I'm hoping to add a second router in a new location, and I use an ethernet cable from the TC at the new router (TP Link Archer C5), updated to the latest version of the firmware. The IP address of the TC is 192.168.1.1.

  I have set up my router C5 as follows: allocation of IP 192.168.1.199, value DHCP = off, and I connect a cable between the TC ports and port WAN (not Internet) available on the C5. In the C5 wireless settings, I tried both using the TC SSID and pw and creating a new SSID and pw. In both cases, the network will work for a short time, but eventually the entire network, including the TC, stops working. I made no changes to the parameters of the TC on any trial.

  Is it possible to use a TC and a router not Apple on the same network? If so, what are the right settings for the TC and the secondary router? If not, is it better to have the not Apple as main router and add the TC to the network created by the non-Apple router?

  Is it possible to use a TC and a router not Apple on the same network? If so, what are the right settings for the TC and the secondary router?

  Yes. That would be the basis of a network of mobile type.

  The key for a roaming network parameters are:

  • The 'primary' router must be configured as a router. In other words, it must have active NAT and DHCP services.
  • All other routers used in a network of roaming must be reconfigured as a bridge.
  • All routers must broadcast a Wi - Fi network that uses the same network (SSID, aka) name, and the type of wireless security, and the password.
  • All routers must be interconnected by Ethernet. To provide Powerline adapters using an Ethernet connectivity should also work.

  If not, is it better to have the not Apple as main router and add the TC to the network created by the non-Apple router?

  Should not really which is the main in the roaming network.

  I think at this point, your current circuit line. To check that, I would suggest that you consider to bring back the router C5 in the same room as you have the TC. Then connect it directly to one of the LAN of the TC ports. Complete the entire upward to a mobile network and test it. If everything works, bring back the C5 in the desired location, and then try again.

  If it fails, then the circuit line will be tested to check that it provides a solid 'Ethernet' connection between the adapters.

• Connection with a switch EZXS55W or a second router WRT54G to my router network WTR300N home?

  I have a home office in my basement with my computer connected to a lan of my WRT300N router that is set up on the first floor and networking with three additional computers to the floor as well. I want to add 2 additional computers in my basement and wireless is not a good set upward because the signal strength is very low. I have great reception on the floor and even on the second floor where my children are connected from their rooms. My question is: I have an older WRT54G Router I use is more and want to know if I can connect it to my WRT300N using the lan line ran down in the basement which is connected to one of the Ethernet ports of the WRT300N? If so, how the connection and set up the second router? Also, I can use Ethernet cables to connect my three computers to the second router or what I need to use the wireless of the second router? I was looking at the switch EZXS55W at the Wal-Mart local and thought that was my answer, but after a search through all the answers of the basis of knowledge here, I'm confused on the approach to take and which one would be the best game for me. Here, any help would be great!

  With the EZX you extended your wired LAN. You can still use the WRT54G to add another point for other cable ports and wireless access. Just do these 4 steps as stated in my previous post.

  You can connect the WRT54G the WRT300N or the EZX. Basically, it's all the same. You don't have to turn off the switch before you connect a device.

  If you want to use the additional wireless WRT54G, you can try to set up a roaming wireless network. Implement the WRT with identical settings as on the WRT300N wireless, i.e. identical SSID and wireless security the same (preferably WPA2) personal with a good password. Do not turn off the SSID broadcast on either WRT. Only the allocation of channels should be different at a time to avoid any interference. Now the devices should be able to move from one access point to another without losing the network connection.

  However, if you perform this configuration test carefully. I don't know how it works if you have a N Router and a G. If this does not work, use different SSID on both. You can then choose which SSID to connect to on the client.

• Add WRT54G: second router / access point, unable to get to the outside network.

  Here is the prob:

  We just got cable internet the other day and the cable operator insisted on using their v1000 Belkin F5D7234-4 instead of my WRT54G V8. So I thought I'd use the WRT54G as a second router/AP (without wireless/LAN/WAN). I was eager to do this by running an ethernet in the WAN on the WRT54G port and plug it into the port of the client on the Belkin, place the wrt - 54 G at the other end of the House and have the WRT54G broadcasting the same SSID and require authentication even as the Belkin and use the Belkin to Linksys Wireless Bridge. In this way, it will extend my wireless network and all computers can access the internet and the other (wireline customers will keep at wire-speed, wireless is not authicate to two different networks.)

  I can't get the Linksys network based able to see all the other computers outside the WRT - 54 G, even for wireless clients. On the side of things Belkin network, I can't ping the router even if she pulls a DHCP in the Belkin address. All customers the Belkin side can meet and thin internet. I've fiddled with the WRT54-g for almost an entire weekend now with no result. The WRT54G can see the other router as a DNS as well as external DNS providers, but none of the client computers can. Basically, I'm wanting to extend the network of Belkin 4 as most cable customers and fill a few dead wireless, and make the visible computer on the same network of suggestions?

  Parameters of WRT - 54G:

  Automatic configuration - DHCP

  Same domain name like Belkin
  IP router set a tire to the DHCP server

  DHCPserver OFF

  Mode of operation: router

  Safe are disabled.

  Wireless SSID is the same as Belkin

  Wireless channel is the same as belkin.

  Method and auth. key is the same as belkin.

  Belkin:

  DHCP is on.

  15 IP addresses available.

  Wireless gateway is on with the WRT54G Wireless MAC address information.

  Ethernet cords are connected.

  I played with static routes for hours, tried the option routing dynamic, even tried DMZing of the WRT54G intellectual property in the belkin and still unable to connect to the internet. Tried the Belkin MAC address cloning. Nothing seems to work. When I plug the WRT - 54G directly in my digital/Modem/phone cable box, I get internet and everything. I'm at the point of throwing same DD - WRT on it.

  But beyond connection "wireless" I discovered really does not work if well (drops random wireless speeds seize up) with two different pieces of equipment running two different firmwares. So the thing connecting wireless set was out the window.

  I however knew what I had to do Linksys firmware:

  1.) DHCP clients forward.

  Customers of Belkin - network

  Linksys customers - network B

  The dhcp pool was not get transferred to the client computers. That is the 1-2 on network computer had XXX. XXX.100 - 102 for 3-4 computers on network B was YYY. YYY. YYY statically set by Windows. Even after changing to a static address on the network A dhcp scope I could still connect to the internet or to one of the computers on the network.

  The static routing table seemed not lead me anywhere either, and I've tried dozens of configurations.

  The way I got it Setup is with the customer enthernet of the Belkin ROUTER to THE Internet on the Linksys WRT54G port 1-4. Maybe I should have plugged the ethernet on the client side of 4 ports Linksys?

  Anyway DD - WRT redirect DCHP feature was what I need.

  Regarding the scenario wireless two routers have the same encryption method and key but different channels and ssid. Who, with DD - WRT for some reason when I jump on the wireless-B, Vista will be ID it as network A (B).

  I hope that it has not violated anything except the guarantee which was anyway. The reason for which I needed for my network up this way is because I do a lot of work using VM (of various operating systems), is simply easier to have two separate semi networks.

• Setup VPN on WRV210 as second router

  I'm trying to set up a network containing two routers, a primary giving me access to internet ADSL (a 3CRWDR101A-75 3com) and a secondary router which has VPN (Cisco WRV210).

  The main router has the following parameters of LAN: 192.168.0.1 / 255.255.255.0 with active DHCP.

  WRV210 has the following parameters of LAN: 192.168.1.1 / 255.255.255.0 with active DHCP.

  The cable connection is LAN port of the first router to second router Internet port.

  In this way, I'm able to get the Internet on 2 laptops connected to WRV210

  I also have a Panasonic IP/PBX connected on the second language (WRV210)

  I need to configure VPN on WRV210 to be able to get SIP calls outside the local network (via internet).

  As I am a novice in networks, both routers are the DEFAULT setting.

  I learned a lot during the last 7 days can understand the concepts of network management, but was unable to put in place the appropriate configuration.

  For example if I change WRV210 router mode gateway mode, I won't be able to surf the internet despite the assistance that says "the mode in which this router will work. If this router is hosted your connection of networks to the Internet, select gateway. If another router exists on your network, select route. When the router is selected, dynamic routing is enabled'

  Also I am able to ping the LAN 192.168.0.x WRV210 first but not on the other side (from primary router WRV210).

  I am confused to use and combine different settings (NAT, routing, Ports,...)

  I really appreciate if someone could provide a step by step to configure the appropriate network and be able to reach my IP - PBX on the second language of anywhere.

  Thank you

  Hi, Ghassan, port forwarding must be configured on the WRV210 router. The 3com device is basically a non-facteurs. If you need assistance with the creation of port forwarding, please call the small business assistance Center.

• Satellite P300-16 t - adding a second drive HARD-success!

  I have added a second hard drive today for my Toshiba P300-16 t.

  I realized that I had a Toshiba SATA drive in a USB disk device that would spare - 250 gb.

  I improvised by removing the feet spread on the cover of the second cage to hard disk using a sharp knife. I put the Bank in place ensuring maximum safety. I also used a heat-resistant material (say what) to secure the drive up as readers are rarer than hen's teeth. I made sure that the reader also had room to breathe. The cover was then released and I turned on my computer and it found the new HDD, the installed drivers at home but hey presto! Another 250 GB to play with.

  Now, I did it is because I call four FSA in the United Kingdom but they weren't any help by providing a cage for the second disc.
  Two said they only deal with businesses and not individuals.
  Others have said that they only provide power cables and batteries!
  Hope that my Tosh never goes down and I must use their services...

  Anyway, I don't recommend anyone do what I just - it is possible if you are a bit adventurous...

  Have you used the Hotglue?

  Surely, you can get the FSA HARD drive media. Unless there is a global shortage on cradles P300: p

• HP Envy 17 K2Z68AV: Adding a second hard drive for HP Envy 17 K2000 Series notebook PC

  So, I have been looking around for more information on adding a second HDD/SDD in my model of laptop computer on the web, but can't find anything on my specific model. Many places say K-series laptops have only one hard drive Bay, and that you use a hard drive caddy optical Bay. Moreover, I found videos of very similar models being dismantled, which seem to have only room for 1 hard drive. However, I was told to support twitter HP want all 17 have 2 hard drive slots. Can I get a confirmation, just to be sure?

  Hey @MrMdr,

  Thank you for visiting the HP Forums! A place where you can find solutions for your problems with the help of the community!
  
  I stumbled upon your post on the laptop and wanted to help you! I looked in your question about your Notebook HP ENVY - 17 t - k200 CTO, model #K2Z68AV and concerns with the second span. Looking to 256 GB SATA m2 (MLC) that could be used for storage only. It is a hard drive, but it fits differently than the main hard drive. Hereis a link to your manual page 2 which shows the specifications.

  It shows you how to install this on page 68 of the manual.

  Please let me know how it goes.

• ATER ADDING A SECOND HARDRIVE MY COMPUTER IS NOT ALLOWING ME to SAVE music to what HE SAID I'm not administrator that he

  Recently, I added a second hard drive and now although I can access my files from the original hard drive, it doesn't let me download files outside such as CD as it says I need to "contact the administrator"! Can you please help me solve this problem? Thank you.

  Hi Paul,.

  In Microsoft Windows XP, the special access permissions are customizable sets of permissions. This means that you can apply special access permissions to files or folders that are located on NTFS file system volumes. This article describes how to set, view, change, or remove special permissions for files and folders.

  Method 1: To take possession of the drive in disk management:

  a. click the Start button,

  b. Select Control Panel,

  c. click Administrative Tools then computer management

  d. open disk management.

  Method 2: Change the drive letter:

  a. click on Start

  b. Select Control Panel

  c. open Administrative Tools

  d. Select computer management

  d. select disk management in the section at the bottom left. You can change the drive letters on the right.
