Why are you supposed to disable DHCP on the secondary (downstream) router? Is this mandatory? Thanks. it depends on what you are trying to accomplish. if you want to isolate the computers connected via wire or wireless to router 1 from those connected via wire or wireless from router 2 then you would put a network cable between a lan port on router 1 and the wan port on router 2 and leave dhcp active on both. if you want to extend the range of your wireless, and want all the computers to be able to share the same set of resources (network printers, shared folders on particular machines, etc) then you want them to be part of the same network address group so you want just one dhcp server and you will want to disable dhcp on router 2 and connect a network cable from a lan port on router 1 to a lan port on router 2 (and you can decide if you want to enable the wireless on router 2 or not, which can have the same ssid and password as router 1 and potentially extend the rage of the wireless coverage). Ok. I have two identical four port wireless routers. I want all computers in the house to be on the same network so they can 'see' each other and share wired and wireless printers. My computers/printers are on different floors of the house, and some are wired and some are wireless. I will place router 1 upstairs, and router 2 downstairs. I connect the modem to the wan port of router 1 (SSID_1). I will enable DHCP on this router 1. I connect a lan port of router 1 to a lan port of router 2 (will this router 2 automatically call itself SSID_1 also, or will it allow me to name it something else?). I will disable DHCP on this router 2. Will router 2 be on a different subnet than router 1? If each router has a different SSID, should I setup the wireless devices (computers and printers, and some smart phones) so that they can connect to both? If each router has the same SSID, then I can only connect to that unique home network SSID. I currently have my four port wireless router on downstairs, connected to the modem upstairs, via ethernet running through the walls, feeding four wired devices and providing wireless connection to all the wireless devices. This setup works very well. I'm sort of thinking that I'll just make this router 2 and leave it where it is, and put the other router 1 upstairs (modem location), connect it to the modem, and then connect this new upstairs router 1 to a lan port of the downstairs router 2 Sorry for all the questions, but I haven't found them all answered by googling. TIA. 1) connect upstairs modem to wan port on upstairs router 1 2) connect a wired computer to lan port on upstairs router 1. open internet browser and point it to 192.168.1.1 and log in with username/password admin/admin or admin/password (for most routers) 3) using the connected computer, configure upstairs router 1 as follows: 3a) wan settings for internet (if dsl you need ppoe and userid/password, if cable you set it to 'automatically obtain'). 3b) configure dhcp for upstairs router 1 to start at 192.168.1.100 for 50 address (192.168.1.100-150) 3c) configure wireless ssid for upstairs router 1 to 'mywireless' or whatever with wpa2 encryption and password 3d) configure lan address of upstairs router 1 as 192.168.1.1 (nothing to change, just confirm the address. 192.168.1.1 is the default for most routers these days) 4) connect in wall (upstairs to downstairs) ethernet cable to lan port on upstairs router 1 5) connect a wired computer to lan port on downstairs router 2. open internet browser and point it to 192.168.1.1 and log in with username/password admin/admin or admin/password (for most routers) 6) using the connected computer, configure downstairs router 2 as follows: 6a) wan settings are irrlevant in downstairs router 2 as you will not use the wan port on downstairs router 2 6b) configure dhcp for downstairs router 2 by disabling dhcp. 6c) configure wireless ssid for downstairs router 2 to be identical as upstairs router 1, namely ssid of 'mywireless' or whatever with wpa2 encryption and password that is same as upstairs router 1 6d) configure lan address of downstairs router 2 as 192.168.1.2 (so it has an address that is unique from the upstairs router 1 when they are later connected together). after you apply this setting you will not longer be connected to the router unless you pointing your browser to the new address 192.168.1.2 and log in again, but there is no need to do it. 7) connect in wall (upstairs to downstairs) ethernet cable to lan port on downstairs router 2 8) restart the computer connected to downstairs router 2. 9) connect whatever wired computers to available lan ports on upstairs or downstairs routers 10) connect whatever wireless computers to 'mywireless' network and the device should select the strongest signel as you move that device about the house. you are done. -you will (later) connect in wall (upstairs to downstairs) ethernet cable to lan port on downstairs router 2 after you finish configuring downstairs router 2. -connect a computer directly to a lan port Thanks, Christopher, for going into such detail, especially step 6d), which I hadn't even considered. I won't be able to attack until this weekend, but will report back when set up. I'm reporting back. It worked fine. I chained two (nearly, it turns out, identical) wireless routers together. Router 1 was connected to my cable modem and set as a DHCP server, and router 2 was connected, lan to lan, to act as an access point. No problems. Thanks. Both routers were D-link Dl-524 wireless routers, but with different firmware, and they had slightly different wireless setup pages/settings. Both allowed for only WEP, WPA-PSK, and WPA. Router 2 also allowed for Shared Key. Router 1, which has been in use for years, has always been configured Open System, WEP, 64-bit encryption, HEX Key, with a 10 numeric Key. If I tried to enable WPA (there is no WPA2 option), the setup screen reverts to Radius Server settings. So, I left it as is, and configured Router 2 the same. I'm not sure if this is the best security I can have, other than maybe using 128-bit encrytion, and maybe disabling the broadcasting of the SSID, which is the same on both routers. My next step is to add printer drivers (wired and wireless) to all computers, and to share printers and files as needed. There are many OSs, so this may be tougher. Thanks again. good to hear that it worked. i suspect that the model number is di-524 (not dL-524). if that is correct then why not download the latest firmware and apply it to each router? but note that there were several versions that had the same model number including the original with no revision number, then revision c, revision d, and revision e. the revision is detailed on the bar code sticker next to 'h/w ver" rec c and above offer wpa2 with a firmware update. anybody with a netbook and the right software can get into range of your wep encrypted signal and figure out the password in a half hour. not that it is likely, but it is entirely possible. not broadcasting the ssid only gives a false sense of security as it is actually still broadcasted. http://www.dlink.com/products/?pid=DI-524 It's been a while, and things are still working fine. But, I was messing around, and discovered that when hooked up as above, IE reports the 192.168.0.2 router (now an access point (AP) with DHCP disabled) as DHCP enabled, and FFox reports it as DHCP disabled. Wonder why. Also, if I plug either my wireless laptop or wired desktop into a LAN port of the 192.168.0.2 router (AP), with the AP still connected to the first router, I can log into both the 192.168.0.1 router and the 192.168.0.2 AP, but as soon as I disconnect the AP from the router, I can no longer log in the AP (or the router) from the laptop or desktop. I was trying this because I wondered what if I wanted to take the AP over to a friend's house, and reconfigure it. This has got me stumped. I do have another wireless, and wired router, that I could turn into an AP and see how they react. Could be the current AP is just somewhat flakey. also, as for your other question, that sounds like correct bahaviour. given that your ap is configured to have dhcp disabled, your laptop or workstation may be able to wirelessly connect to your ap but it will not become part of the network as the ap is not issuing it an ip address (dhcp disabled). you can manually set an ip address (in the same ip range but not one that is already in use) on the workstation to allow you to then navigate to the 192.168.0.2 access point configuration page. |
