Home Network :: Router Not Getting IP From Modem?
Feb 12, 2012
so yesterday I went out and bought a new Cisco Linksys E4200v2 router. My ISP is Communicomm (terrible, but they're the only one here). I also have a Terayon TJ 715x cable modem. I shut down pc & cable modem, connected everything, and powered back up. I am able to access the router config page at 192.168.1.1, but the router does not receive an ip address from the modem. If I plug the modem directly to the pc, I get an ip and am able to connect to the internet. I have called my ISP several times, and they tell me that they do not use MAC address filtering. The only MAC address that they need is that of the modem, which they have. This modem has been working fine for several years. After spending over an hour on the phone with Linksys support, they have determined that the router is functioning properly.I also tried hooking up an older netgear router and got the same results. The following is my ipconfig with the modem connected directly to the pc. [CODE]

I have a wireless modem on the first floor of my house, where I got cables through the wall running throughout rooms in first floor, ground floor and basement.I have my small business at the basement, so I have 2 PCs one printer and one external hard disc which also connects directly to a modem/router.I have 3 PCs from the first and ground floor that connect through the wall to my modem, and everything works well. But for my basement, which only has 1 lan cable output on the wall, I got myself a router so that I can connect all my devices.I connect the router with my modem, and then the PCs, printer and hard disc on the router. The PCs have internet access, so I know the connection to the modem has nothing wrong to it. But I am not able to access the PCs connected to the router from the PCs connected to the modem, or vice versa.
I was told to not obtain an IP address automatically, so I assigned my modem and router to work on 192.168.10.x and gave my PCs IPs such as 192.168.10.19 Only after setting this up did all my PCs have internet access, but again, no network communication between PCs on modem and PCs on router.One thing that might be worth mentioning, is that through time, my network keeps going from Home Network: Network, to Network 2, Network 3, and so on... now it's on Network 5. I have no clue why this happens, and if it's related to my problem

I'm having trouble connecting my 02 dongle to the internet using my router. My router is a TP-LINK MR3420 and my 02 modem device is E1752. I checked to see if the modem is compatible and it says it is. I went through the configuration that was given to me with the router and I tried using you tube but nothing. Do i need to get a static I.P address off my Internet provider? If I plug my 02 usb dongle directly into my computer it works perfectly and I got the router to work using a ethernet cable and plugging it into the WAN port at the back of the router but I would prefer to let it connect through the 3g port. I get a connection at 40% and 100 bytes are sent and some are received but the connection drops. Is it a problem with the connection? I will upload a image.

Lately I've been experiencing connection problems between my router and cable modem. Every night after 11:00 PM EST, my Internet connection sporadically goes out. I called my ISP who said there was nothing wrong on their end. Plugging directly into my modem allows me to access the Internet. When I wake up in the morning, the connection is back until 11 or later again. I ran WireShark but I'm not sure what to be looking for. There are a lot of random things from the LLMNR protocol like standard query A zmtvrjaql.

how to properly configure 2 different hardware devices to extend the current wifi signal of my home network.I'm using a Motorola SBG6580 DOCSIS 3.0 cable modem as my primary access point (AP) and a Netgear N300 DGN2200v1 ADSL2+ modem router which will function "behind" the SBG6580 in repeater mode. I previously had DSL for my internet connectivity but recently switched to broadband cable for faster speeds.Due to the layout of my home, I cannot physically connect the Netgear router to the Motorola modem via ethernet cable and need both devices to communicate wirelessly. I have already done extensive reading on this subject and best practices suggest that, whenever possible, both units should be the same brand/manufacturer. The Netgear appliance does have the capability of being configured as a repeater so if I don't have to buy a "network extender" that would be my preference.I understand that both units must be configured to have the same SSID, subnet, wireless channel and security encryption. In repeater mode the Netgear router can't be configured to use WPA2-PSK so I need to use WEP instead.

I'm experimenting/attempting to use a laptop as a network tap between my (DSL) modem and a wrt54gs by creating a bridge with two NICs in the laptop. My problem is I can't seem to get connectivity on the user end of the router. I can't ping the bridge from an end computer...
DHCP is disabled in the router, but even when manually configuring the IP address on an end computer and using the bridge as a default gateway I can't ping out.
Am I completely misunderstanding the purpose of a NIC bridge?

What I learned was it was bad to connect directly to the modem because you are left open to the internet. Currently my friend just got the internet and I told them to buy a router but they did not, and just have it directly connected to the modem. Is this fine, because they only have one computer, and it works fine for now, but wouldn't this be prone for attack?

I think that my ISP is throttling my bandwidth at the modem . how access full available bandwidth.When the technician installed the fibre optic line and then the modem, he showed me an amazing 77MB/s (about 600Mbps) before the modem!!But after the technician left these were the test results after the router:
1) SpeedTests.net:
averages, after router, show: UP between 56/60Mbps & DN 45/75Mbps
2)Local Server Speed Test:
average: UP 45Mpbs & DN 170Mbps
A Japanese Internet savvy guy explained that NTT East throttles the available bandwidth at the building by specific apartment/modem settings related to individual contract bundles. I signed up for the top bundle: TV, Phone and Internet connections.This is my Hardware/ software setup:
OS: Win7,
Line specs:
Line type: IEC60874-14
Connector type: SC
Core across: 9 micrometers
Clad across: 125 micrometers
ITU-TG-652
NTT East fibreoptic TV/Internet/Telephone bundle (100Mbps best effort) Hikari Next Family Type but 10Mbps is considered within parameters
Asahi ISP Internet contract
Modem:
GE-PON (WAN+Coaxial TV antenna)
"SCM-GE-PON-<H>A GV-ONU D<1>" model
Router:
RT-S300HI (4 Giga ports + 1 phone)
Router & Modem have Japanese firmware which I cannot understand and, according to the NTT East, I must rent both modem and router from them and "will not support any other modem/router setup".I could not understand if it was because of technical or contractual limits.
I have tried to test my throughput after the modem but I could not figure out where the DNS, IP, WAN etc strings of numbers should go and, in the end, I simply cannot connect to the internet from my laptop directly to the modem so I cannot perform the same speed tests after the modem.

I have Zyxel Modem configured in bridged mode with static IP from ISP. I want to connect multiple PCs to modem via switch so that each PC use the same configured Public IP address to use the internet. For this (generally) I would need to configure NAT for that IP. But I want to know that will it work under bridged mode or not?

I had Symfony modem with Asus ap and 1 d-link switch. i changed my modem because that was old and bought TP-Link(TD-W8961ND).It is connected to the Dlink switch and the switch is connected to the Asus Ap(RT-N12) The situation was the same just modem has been changed. Now i have this problem: i have internet with cable every where...behind switch or behind Ap...but when i wanna use internet with wireless via Asus Ap it doesn't work i checked every thing...the Asus Ap has 3 mode(Ap,Router,Repeater)...i chose every one but only repeater mode works. by the way with modem wireless i can get to the internet but the signal is fair for me to use!

I have 3 pieces of hardware:
1. Green Packet DX-230 WiMAX modem with router
2. D-Link DIR-615 ver G2 (from my ISP)
3. D-Link 8 port desktop switch
I previously used the DIR-615 with my high speed broadband connection. However I had to move to a new house and here I can only get WiMAX. I want to...Place the WiMAX modem upstairs to serve as modem and wireless access point Have the DIR-615 function as the main router and firewall (downstairs) Use the switch to connect all the rooms in my house FYI my WiMAX modem has no connection configurations. I just plug it in and it'll connect automatically to the WiMAX signal. It has 2 LAN ports but no WAN port. From my understanding of networking, I have to turn off DHCP on my WiMAX modem, put it in the same IP range as my DIR-615 (192.168.0.100-199), and disable UPNP and NATPMP. After this I'm stuck.How do I tell my DIR-615 to use the WiMAX modem as it's WAN connection?Should I reserve an IP for the modem in my DIR-615?

is it possible to connect the wan port of a cable modem to a lan port of the home network? the reason is, i need some wifi access and more ports to my wired network, and the most reasonable solution would be a cable modem router with wifi and 4 ports just plugged into one of my routers.

My home lab is in a different room than the cable modem. I have a wireless N router in the room with the cable modem. I have a wireless access point that is connected to a Cisco 2611XM routers fa0/0 interface. The 2611 accepts the DHCP address from the wireless router. However, I can't ping past the wireless LAN 192.168.10.0 network. I know with the wireless router it's two layers of DHCP. Should remove the DHCP settings from the wireless router? The wireless router is a TrendNet TEW-651BR. I can ping my iphone or any device conntected to the wireless router. And my laptop can ping default gateway of the wireless router, which I assume is the cable modem, however the 2611 cannot. So I'm assuming that's why the hosts behind the 2611 can't get to the internet. I followed the below instructions. I know the instructions don't assume your using a wirelss router between 2611 and the cable modem. But, I really don't want to run a cable to the cable modem.

I have a Time Warner Cable business class service with no static IP, with a wireless modem which is plugged to a CAT5 distribution panel. On the jacks (2 other rooms on the house) I have a Linksys E3000 and a Linksys Valet router for signal boost and gadgets usage (TV, cameras, etc).The main router (TWC) has it's own external IP which TWC assigns to me and internally distributes via DHCP the range 192.168.0.x. With that said:
- The E3000 has a 192.168.0.6 IP -- this is fixed setup on the TWC router (ubee brand) by MAC address
- The Valet has a 192.168.0.7 IP -- this is fixed setup on the TWC router (ubee brand) by MAC address
- The main router has the 192.168.0.1 as the gateway and web-interface
Whenever I connect something to the E3000, it is distributing the 192.168.1.x range and the valet 192.168.2.x range.That works perfectly for my home based business until I decided to use more stuff on the network such as a IP printer, IP cameras, etc.
- The IP cameras are connected to the E3000 due to signal strength and I have manually assigned them the 192.168.1.15 and 192.168.1.16 IPs and ports 9001 and 9002.
- The printer is connected to the E3000 and I have manually assigned the IP 192.168.1.30.
Issue 1: Port forwarding On the main router (TWC - UBEE) I have tried to setup a port forwarding by informing the Local IP as 192.168.0.6 (E3000 IP), Internal Port 0, Public Interface IP (0.0.0.0), Ext Start Port 9001, Ext End Port 9001, Protocol - Both, Enabled Yes. On the E3000 I did the same config (screen shot attached e3000.png).This is not working properly. I can't get into the camera.
Issue 2: Printer/ The printer is only accessible if I connect to the E3000 (because it is on the 192.168.1.x network)
Issue 3: How to configure all the devices on the same subnet? If I want everyone to be on the 192.168.0.x network, how to configure properly the E3000 and the Valet? I have tried to force them into the same network but it would not work properly. It would not get an IP from the UBEE router (main).

Here's the layout: Cable modem in the basement. Several devices in which I'd prefer a wired connection in the basement. Upstairs on the 1st and 2nd floor of the house are many devices in which wifi is fine or preferred.Here's the problem: As you might guess, wifi is weak upstairs and certainly on the patio and 2nd floor. I have an access point upstairs that I've experimented with but it is flaky.

I am a new student in networking, taking the CCNA courses, and now want to rewire my home. I currently have a cable modem and E2500 setup running my network. I want to get the modem and router out of my computer room and in the basement where the cable enters the house. I want to do this to clean up the computer room wiring a bit and to run line drops to different rooms in the house where the internet will be utilized.Currently there are two PC's, a laptop, a tablet, sometimes a phone, and an XBOX using the internet. I want to get my printer back up and running on the network but thats another story. Only one PC is currently hardwired. I would like to run two cables into the room with the PC and XBOX that are currently using wireless, at least two into the computer room for the PC and network printer, and one or two into the living room for the blue ray player and possibly an internet tv.

I have setup a webserver on my home PC and I have forwarded port 80 on my router to the IP adress of the PC that is running the web server. The web server is working great; I can get to my web pages from outside of my home by going to http://MyIpAddress/Anyway, the problem is with the Windows Media Player plugin I'm using. I want to embed 6GB MPEG-2 videos into my web pages. I have some videos on my PC and I want to be able to watch them remotely by connecting into my web page. It works fine when I'm at home; other PCs can connect and play the videos no problem. The problem is when I'm at work. When I'm at work, I go to my web page (via my IP address in a web browser) and the Media Player plugin says "Connecting" for a minute, then it says Ready, but the video will not play. I tried using a smaller, AVI file (680 MB) instead to see if the problem was streaming such a large file, but the video still would not play.Do I need to foward more ports on my router so that Windows Media Player can connect back and get the information it needs?

Every time I connect to my home network with iPhone 4 my whole network stops working. Windows 7 is not reporting any problems with connection, nor is my router. I have cable connection with my PC and wireless with my laptop, they both just stop working without any visible reason. Even the iphone i connect with wont work, but of course it says its connected and everything is ok.I tought it was an iOS 5 problem, so I reinstalled it. It worked for an hour then its all back again. I even tried sharing my PC conection so that my iPhone is connected to PC and not directly to router.But that produced the same results.

My Set up at home is as follows: [code] Now according to what I have read I should be able to set the subnet on .2.0 network to a subnet of 254 and this gives me 512 Hosts I believe however my question at this point is how to route between 192.168.1.0 and 192.168.2.0.Or when I set the subnet .254 does the router just route it automatically.I would still set the subnet mask on both networks to 254 correct? I believe I can only use 192.168.0.1 to 192.168.1.255 w/.254 subnet mask. However I already have some servers that are configured with applications (On the 192.168.2.0 network) that I do not want to change ips on because it would be a pain to reconfigure so, my other question is other than using .252 to extend it to 192.168.0.1 to 192.168.3.255, (I need the 192.168.2.0) is there anything I can do? Like use 192.168.1.0 with subnet mask of 255.255.254.0 to get the 192.168.2.0 network? The reason I asked is I was using a subnet calculator to try and figure this out but every time I put in 192.168.1.0 with .254 subnet mask it changed the ip to 192.168.0.1 to 192. 168. 1. 255.I would really like to use the netgear only. The way I have it now is not working I am able to ping the internet from the 192.168.1.0 network but I can't ping from 192.168.2.0 network to the 192.168.1.0 network.

At the moment I have my home network (192.168.0.0/24) like as below (all connect using straight cables): [code] My Cisco lab equipment are in the basement all connecting to an access server which at the moment is plugged into Switch3-dumb (along with a printer & NAS).What I'm thinking is to replace the Switch3-dumb with a 3550 I'll be picking up later this week.Then using this to do as the Switch3-dumb did maybe by creating a native 'vlan 192' & putting it into a gig interface which will connect to the network using the straight cable, also putting the printer & NAS into the same vlan.This will hopefully still give me connectivity throughout.Then when required I'll like to use the 3550 with the rest of my Cisco equipment for setting up different labs (segmenting them from the home network by using different vlans etc.One of my reasons to implement the 3550 into the home network is to be able to play about on a regular basis (port monitor, traffic stats, etc).

My Wifi network has a wpa2 password that is a random string of characters and numbers and yet last month a rogue IP Address kept popping up on my DNS list. It has to be coming from my neighbor who's bedroom is about 15 feet away from my router. So unless someone is sitting out on my front lawn to do this then it must be him.I've been looking for software that will notify me when a connection my router is attempted and kudos if it also asks my permission first would be great.There are wifi packet sniffers out there like Cain&Abel, Airsnort, that sort of thing but I am not quite savvy enough nor do I want to turn this into a complicated hobby but just need a basic warningin case something gets past my passwords again

2. A laptop, with wireless connectivity (again on Win7).
3. A modem, UTStarcom WA3002G4 with an internet connection from BSNL.The modem is a wireless modem.
I want to be able to connect the laptop and the desktop in a single LAN connection, so that
i)I may play NFS Most Wanted on both the laptop and desktop through the LAN play.
ii) I may share files and folders, fast and without any hassles.
