Linksys Wireless Router :: WRT610n 2 Networks From 1 Comcast ISP Cable Modem
Jan 12, 2010
I have a need to have 2 seperate networks from my comcast cable modem.I was hoping to plug a 5 port hub into the cable modem and then plug both the wrt610n and the wrt54g into the hub. Seem that only one of the routers will get an ip assigned from Comcast.Is there a way to have one ISP cable modem and create two different home networks with the two linksys routers, thus two separate independent networks?
-Network 1: public household use and family (Jane's wireless laptop, household PC's etc).
-Network 2: private household/company use and separate from the public family network (company wireless laptop/company PC, un-secure media server).

We have kids in the house and I'd like to limit their internet access to certain times of the day but because of the great amount of devices they use (phones, tablets, laptops, etc.) the only way I could think of doing that easily was to set up two wireless networks: one that the adults could use 24/7 and the other that the kids could access during certain set hours.
Here's the equipment I'm working with:
DLink DIR 615 wireless router
DLink DIR 515 wireless router
Motorola Surfboard cable modem S85101U
I plugged the DLink 615 in, set it up for DHCP client and plugged it into the cable modem. I lef the default 192.168.0.1 IP address for the device. On that router, I also reserved the 192.168.0.199 IP address and assigned it to the DLink 515.I also gave the DLink 515 device the IP 192.168.1.1 so I could administer it.I set the DLink 515 to static IP and made the IP 192.168.0.199 and the default gateway 192.168.0.1.I plugged the DLink 515 into one of the LAN ports in the DLink 615.I set a schedule on the DLink 615 to shut down internet access to the DLink 515 at a certain hour and turn it back on at another time.Everything seems to work ok, but at least once a day we have to unplug and plug the routers to reset them.

I've got a ASUS AC66 router plugged into my Comcast cable modem (regular dumb modem), it's running the Merlin (OEM-modified) firmware.I've got a Netgear 3400 router flashed with DD-WRT (latest build), it's a replacement for another N router that died on me.
Anyways, I went to set client bridge like always. Main router is 192.168.1.1 so I set DD-WRT router as 192.168.1.2, set the wireless modes to client bridge with matching SSIDs for my 2.4/5GHz radios, input the correct security keys on the security page (AES), then I put the router in router mode (from gateway) Basically, I followed the instructions on DD-WRT's website, which worked perfectly until the other router died.
This time around as soon as the DD-WRT router reboots with its bridge information saved it immediately causes some sort of conflict on my network and kills the internet and all network connections. All devices lose their IP address. It's like the DD-WRT router is somehow shutting down the network and my default router.

I bought this wonderful voice gateway off the internet from someone. So not sure if they ever used it with Comcast.So far I hatve had no internet once I plug it to the cable. I have asked Comcast tech for activating this device. However they say it is not supported and they have tried sending it the Activation signal but they say it fails. I can see all lights lit up and go green when I connect this device to the cable, is there a firmware upgrade for DPQ3925 ?

Comcast had us unplug our modem in order to upgrade to their new faster speed. now our wireless router won't work. We've reset the router twice. we can set up the wireless network but we cannot connect to it. The connection last for about 5 minutes and then we get an error, cannot read IP address. Comcast says it is not their problem and linksys says they can't assist either.

Our small business just moved into a new building and I am in charge of setting up the network infrastructure. I am not new to computers or networking but I have never had to deal with this set up before.
Our current set up.We have a cable modem from comcast that has the Coax cable connected to it.The modem has 4 ports on it. The ports are connected to a built in 24 port switch that was already in the building. The switch has it's ports connected to outlets in the walls. Currently we have 4 computers on our network and since the cable modem had 4 ports it worked fine.
What we need? We will have another person join our office so I will need to activate one additional port on the switch that already exists. However, since all 4 ports on the modem are already taken, I have no way to add an additional port. They also want us to get wifi in the building.How I think I have to solve the problem (most likely wrong).I have to get another switch (like 8 port) and connect the cable modem to the switch using a cross over cable (if there is no designated internet port). Since I have the modem connected to the switch, I will have to move the 3 remaining connections to the switch.
Then I connect the 4 remaining ports on the switch to the existing 24-port switch that is already there. I will use one of the outlets in the building to connect an AP for Wi-Fi for better signal. Currently the modem and switches are hidden in a closet away from the office space and would mess up the signal.

I was very happy working with my WRT610N connected to the ethernetport of my previous internet modem. Recently I had to switch to a new modem CISCO EPC3925. Unfortunately this combination does not work anymore. I don't get an internet connection on my WRT610N anymore. I therefore have to connect all computers (LAN and WIFI) to this EPC3925. Especially for the WIFI I'm not fully happy. My IPAD2 sometimes does not want to connect, a problem which never occurred when connecting to WRT610N.
I probably need to change a setting, but where? In the EPC3925 or in WRT610N?

I have a 192.168.1.xxx network connected to Verizon FIOS via Actiontec MOCA / router. I also have a 192.168.15.xxx network connected to Comcast via Motorola VT2442 router (used for Vonage) and a Motorola SB6121 cable modem.
Each network has it's own gigabit switch connected to each router. The two networks are physically separated but switches and routers are physically side by side.
What is the best configuration to allow devices on 192.168.1.xxx network to communicate with devices on the 192.168.15.xxx network (share printers, NAS, etc), but still have each network served by it's respective ISP, and each device still get it's dhcp, dns, gateway, etc from each respective router?

I am swapping my AT&T DSL and Comcast cable for U-verse. In the basement, I have a Netopia DSL modem connected to a Linksys BEFRS81 v. 3 ethernet Cable/DSL router/8-port switch. Cat 5 cables are attached to the router, then run throughout the house so we are "networked" to the DSL modem and use a patch cord from laptop or desktop into the wall to get to the Internet.

Using a Linksys E2000 and Linksys WRT54GL (both flashed to most recent firmware), I am trying to set up Network "A" and Network "B" on one modem. I do not want either A or B to be able to see each other for security purposes. Both are secured networks for the wireless connections and have different SSIDs.
After online research, and the inability to find my exact question answered, this is what I did and I'd like to know if I'm missing anything to keep A and B completely separate. Or, if I've done anything that will cause any problems on my network. [code]
I disabled the ability to change settings using wireless connection on both routers.

We are a small office currently running a regular network (9 wired, 2 wireless) and also using the "guest" feature (7 wireless) on a Linksys E2000. We have a switch to connect our wired equipment to the E2000. If "A" is our regular network, and "B" is our guest network, is it possible to have 2 routers on 1 cable modem and still prevent network "A" from seeing Network "B" and vice versa?? We are looking to do this because we will soon be exceeding the maximum guest users (10) allowed by the E2000. We have another Linksys router in storage, I think it is a WRT54G, that we would use if this is possible.

Every day for the past week my Internet access goes down. I have a netgear router connected to Comcast modem. I have to reset the modem then the router constantly and it gets irritating. I called comcast and they say reset them. But why should I have to constantly reset.... Sometimes I just ignore it and it comes back up later... what is going on??

I can't get a new IP from my ISP when my Cable modem router(EPC3925) is set to router mode, i have tried factory restore, unplugged etc..but still no luck. It changes each time i reset it when i set it to bridged only mode but then i won't be able to connect other devices to it since it doesn't uses DHCP in bridged only mode. It changes back to the IP i had when i set it to router mode. I don't want to change my router settings to bridged only because it would disconnect the other devices in my house. Why my ISP assigns the same IP address when it's set to router mode but assigns different IPs when it's set to bridged only, how is this possible ?

Our router is connected through a cable modem and If I connect my computer directly wired to the cable modem, I have no problem, it does not disconnect at all.In comes the router in between, when I connect the router and connect my computer through the router WRT54G2, it works initially then I get disconnected after about 1-2 hours. This is very regular. I have a temporary solution by resetting the router via two ways:
1. Go to the admin page, and perform a release and renew IP method.
2. Simply power off the router and then on again.

I have an EA2700 (fimware "classic" 1.0.14.129982) that used to work perfectly fine with a Comcast cable modem. I just recently switched to Charter with an Arris TM902 modem and that's where the problems started. The cable modem will not recognize my router. I have to plug in a computer into the cable model when it starts up. Then I need to clone the MAC address and restart the router (after disconnecting the computer). Why isn't the cable modem recognizing the router when I restart it? I guess this could work if it would be a one time thing but I had to power-cycle the modem and it stopped recognizing the router even with the cloned MAC address. So I had to do the whole spiel again.
Is there any way to make this work easier? Should I update my router's firmware to the "smart" one?

I have a Linksys WRT54GS, version 6 with Mac OS X (version 10.6.8) hooked up to a Scientific Atlantic cable modem, with RCN as the ISP.
Recently, RCN had some network issues, and so I had to power down and reset my modem. The modem is working fine now -- no problems at all when the Mac is connected direclty to the modem.
The router's network is OK in that I can connect the Mac wirelessly to the network, but I can't connect to the internet through the router (through neither the wireless or wired connection).
I have downloaded the latest firmware update for the router, following the Linksys site instructions.
I did call Linksys tech support on the advice of RCN, and they said that the router does appear to be working (power, WLAN, and Internet lights are on), but they would be charging me nearly the cost of a new router to fix the problem.

I switched to xfinity and I really don't feel like renting their gateway for $7 dollars a month. Gateways are crap anyways. So do any of you know of a good router and modem that can be paired up to work well with xfinity and has good speed?

I want to create a DMZ by having a less sophisticated router connected to cable modem, which would have the webserver which contains no sensitive information, and then the EA3500 to which my laptops and desktops which contain sensitive information would connect to. Can CCC work through that first router?

Reset to factory defaults. DHCP turned on. Status page shows black for router IP, gateway, and DNS addresses. Powered router+cable modem on/off multiple times already. I also have another wifi router (WRT120N) and it works fine.
Pretty simple connection. Just a ethernet cable between the cable modem and E1200 internet port (Cable modem <---> E1200)

I am using wag120n modem router but is confused abt how to setup it's wireless security.The wireless securit setting recommended in tutorial given here is very different from what is given in my routrs setting up page.
I don't know how to handle the key renewal option.If i leave it as 3600 seconds does that mean i have to enter a new key in my wireless device connected to the router after every 1 hour?

I just switched to Roadrunner Lightening via Brighthouse Networks. There is no configuration capability in the Cable modem/ router / wireless - Ubee provided to make the Modem a bridge. You have to call Brighthouse to do that. They indicated that they only do that for supported routers and the EA 4500 is not one of them. I'm ready to call them to say I have one of the supported modems so "do it" and then find out what happens.
Meanwhile I have connected my EA4500 through their router and have a network in a network. I've noticed another more significant problem. The speeds through the EA 4500 drop to 90%. Is there something wrong with the router configuration that would cause this significant drop in speed? I'm afraid if the problem is the EA 4500.

i have an e3000 linksys cisco router. i havent had any problems before until i tried adding a new computer via cat5e ethernet cable. The first computer always is connected fine whether i unplug the router or modem in any order and replug. i dont know much how to fix this. ive tried some unplugging method once but it only worked until i turned the computer off and back on later. i am also running 2 xboxs with no trouble. i used cisco connect to diagnose problem but it just told me to unplug modem power and tv cable and i did that with no luck.although i have good equipment, the internet is pretty slow.i have the best service of my provider that states it has upto 50 mpbs download speed.i ran the cisco internet speed test and only got a max of 20 download and 5 upload.how could i speed this up?

We have a E3200 wireless router but our only connection is wireless. There is no Ethernet connection or cable modem. Presently I am unable to bring up the web page ie...10.100.x.x for entering the id/pw to login. Router is setup with default settings. Is there a setting that needs to be changed from the setup menu or this type of setup will not work with this router.

Attempting to get EA6500 working with TWC Motorola Surfboard SBV5220 modem, which has been working just fine for the last 2 years with a Linksys E3000 router. DHCP client in the EA6500 either doesn't ask for an IP address from the cable modem or the modem just isn't supplying one. With the E3000, you could see the IP address assigned by the cable modem and the primary and secondary DNS server addresses provided, and if the DHCP request didn't work, these addresses would be all zeroes. But, with the EA6500, I can't find an equivalent screen that shows these assignments, or zeroes when the DHCP request fails.

I am at my wits end.Comcast just changed my old RCA cable modem for an Arris Telephony modem.(I had Comcast phone service added)The tech that did the install said the wireless G network was all up and running. (My 3 other computers and printer) Well lo and behold the network does not work at all. I only get internet through my wired computer and cannot access my router through 192.168.1.1 anymore.I tried powering down the router and modem by holding the reset for 30 seconds and unplugging them.
