Apr 21, 2013
I have one interface setup to a Cisco 2921 router connected to a Cable modem.DHCP is on the 2921.when I connect to the ssid for my guest i'm redirected to the authentification portal 1.1.1.1 .i'm putting valide credential and when pressing the submit button .. it just go anywhere.
I have setup another SSID with a psk and it's working fine.. getting ip and able to browse internet.From what i have read... it's apparently DNS issue on my router.. but what should I check.

I have two ASA 5505's. One is currently setup as my firewall connected to the Cox Cable modem and wireless AP. I have another ASA that I would like to use, I have an idea that I could set that one up as a VPN unit, but not sure how I could do that. If that is not an option, can you provide the command line instructions on how to setup the VPN via the console cable. [code]

I have DOCSIS 3.0 modem and a Linksys E1000 wireless router with which I get reults from SpeedTest of 8.6 mps down, 1.57 mps up up from 15 mps service from cable provider. Connected to modem via ethernet cable produces 16.0 speeds. Do I need to upgrade the router or are my settings wrong?

I recently switched from dsl to cable. I have a e2000 router that I would still like to use. The modem I have is a Motorola Surfboard SB6121. It has no options that I can modify. The modem has a built in DHCP server. However, I can't modify it and I don't like the ip configuration it uses. For the time being I have the modem connected to a switch which is working fine. What I would like to know is how to configure the e2000 to use the modems connection. I used PPPoE for DSL and had login information.

I just moved into a new house.The house is wired with cat5e.my plan was to connect my cable modem to a multiport router. All of the cat5e cables will connect here. I planned on having my wireless router connect into a cat5e rj45 plug in the house. my laptop knows the wireless is there but it can't communicate.What do I need to do to allow communication?IP and subnet addressing

I've been having problems with the router portion of my cable modem router. I have a brand new router that I would like to use rather than the crappy router that is part of the cable modem.The problem is that I'm not able to get online no matter how I set the settings. I have disabled DHCP in the cable modem router and am connecting this to the router thru the internet port of the router.

Im trying to setup a cable modem which is also a router that has a printer attached to one of its lan ports. From there it connects to another router which connects to other clients from there i have another router with a VPN connection with other clients. I would like to be able to see everyone on the network. How do I setup the routers in particular the router with the vpn which is the last router. Also the vpn router is connected through its WAN port to the router ahead of it at its lan port so it can use its VPN connection.If it makes it easier lets ignore the cable modem as router and ill find the printer another way of connecting but essentially i need the two other routers for two ip addresses. One for the first router with my regular IP and then the other is for VPN IP.

I have a Netgear 600 dual band router connected to a DOCIS 3.0 cable modem with a 25mps internet connection from my ISP, should be fast right? When I run a speed test on my comp I get 10-13 mbps download on average. Here's the issue, upon visiting my mothers house and running the same speed test I got very similar results. She is running a Lynksys G router on a DOCIS 2.0 cable modem with 12mps connection. My question is, how can this be so, am I at the limits of my comps g network card? as a disclaimer I would like to note I am connected to the G band on both routers.

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.

A friend recently re-installed windows XP on their HP Laptop. They were connected wirelessly with a Linsys router (model wrt54g.1) and an RCA Cable Modem. The Cable ISP can ping the modem and gave me the IP address over the phone. I cannot ping the modem even when I take the router out of the loop. The network card (i1394) in the Laptop is functioning normally and I can see traffic on the modem (both the Cable Internet light and the PC activity light are flashing green) the ethernet port on the laptop is also flashing (amber). However I cannot reach the internet and cannot even ping the modem. The modem is brand new..

I can't seem to setup my WAG120N modem.I kept on getting the error "your ethernet cable does not appear to be connected properly" even though I have connected all the cables correctly. I can access the modem through the browser via 192.168.1.1 though.I thought the setup is supposed to be simple but I have wasted few hours.

Today I purchased a Motorola SURFboard extreme Cable Modem DOCSIS 3.0 in order to replace my old modem which is out of date and has been very slow as of late. I connected the coaxial cable, Ethernet cable(to Linksys wireless router), and power expecting it to simply work. All four lights came on green (power, downstream, upstream, connectivity). The downstream light turned blue which indicates a bonded connection.The device light was blinking on the modem. I connected to my wireless router, but no internet access. I then tried connecting my laptop to the modem directly via Ethernet cable, still no access. I think that rules out the router being the problem. I also ruled out my laptop being the problem as the same thing is occurring with my other laptop and desktop. I called my ISP (Cox Cable) and had them re-establish connection with my modem, this did nothing. I thought for sure this meant I had purchased a faulty modem; I hooked up my old modem and the results were the same, the modem connected fully with no problem (all four lights were green) but I have no internet access.

I'm going to lay out my equipment and how Id like to set it up. Im hoping to get some feedback on specific settings for my equipment as I am rather clueless. How I'd like to have everything running:internet through the gateway (obviously)E3200 setup as wireless router with HD and TV connected.NAS on E3200 for backups and dropping files on to watch on TV both laptops login manually to VPN service.I was previously able to create a symbolic link in windows for dropping files onto NAS easily enough. I wasn't able to see the HD on the TV using it's MediaShare function. That was one of the main reasons why I got the E3200 with USB port.Also, when I connected the TV to the E3200 after setting up my previous RG with E3200 I couldn't get internet signal. With the DLNA function of the TV I'm thinking it might be a situation where I have to access the symbolic folder on my computer in order to access the NAS. This would probably be a painfully slow nightmare but the only solution I can think of.

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 ?

I'm using a refurbished WRT54G2 v1.5 router. I've had the router for two and a half years and have never had a problem. I recently unplugged my DSL modem and this router to move them, and when I plugged them in again, the router stopped picking up the internet signal from the DSL modem. I'm able to get internet when I hardwire directly to the modem though. I tried resetting the router and setting the router up from scratch again, but now I just get error 321 Ethernet cable not connected when I try and run the setup cd.

I used to have this exact setup with 2 wrt610ns i believe was the model number, i have one at my house, connected to my dsl, and then another in my "man cave" connected by a approximately 250 foot buried outdoor cat6 cable, inside of conduit of course. Last week both routers along with my modem were fried during a storm, so now i rebuilt the network with 2 e4200s, i hooked everything up and b4 i even had a chance to set my network up like i had to do b4 (a 192.168.10.1 subnet in the mancave) everything was already getting internet, however i cannot access the web based setup for the 2nd router (mancave) the dhcp client table shows it with an address of 192.168.1.139. even if i disconnect, reset the 2nd router and set it up on a 192.168.10.1 address as soon as i connect it to the main router, it goes right back to the .1.139 ip address. the only problem i have with this is that i would like to have the freedom to change my wifi passwords or edit other settings on my network without having to disconnect from the main router everytime, assuming that will work and i wont have to do a hard reset in order to get the router back to a default ip. the cable connecting the 2 routers goes from a lan port on the 1st router to the internet port on the 2nd.

I own a Broadcom BCM5354-based wireless router (Tomato 1.27 flashed) and an Aztech DSL605E modem. When both are powered up, the wireless router sometimes doesn't get internet access because the modem automatically logs itself in. I have to plug the modem cable to my laptop, manually disconnect the modem, and plug the modem cable back to the router to fix it.

How do I setup a E3200 router using a wireless USB modem to connect to the internet? This is my only choice, I do not have a wired connection and I do not own the telephone wires and there is no permission to do otherwise.

I'm switching to cable internet service instead of DSL. My Netgear router will not work with my cable modem; but it works like a charm with my DSL modem. Is it a problem with the router setup? Good thing I still have the DSL service.

I have desktops hardwired to a switch, which is connected to my cable modem. They pull a 10.x.x.x ip address with DHCP. I have a wireless modem (e3200) connected to the cable modem. My wireless devices pull a 198.x.x.x ip address. Can connect to the internet just fine, BUT..Because of this (im assuming) I cannot add my printer to my wireless laptop. Different networks, wont connect via share name etc.So, if i turn off DHCP and NAT on the wireless router, shouldnt my laptop pull DHCP from the cable modem and get a 10.x.x.x IP address while connected wirelessly?My wired computers can connect to the shared printer just fine, only my wireless computers cannot. I have another printer that is networked (connected directly to the switch, no computer) with a static ip of 10.x.x.199. My laptop can connect and print to it just fine. I just cant connect to the printer that is attached to the 10.x.x.x computer.

Have had ADSL installed through a router, connected the wireless router and it works fine Have since connected the original router via -120mtrs of CAT5 cable to extend to the house. Connection through LAN is fine into desktop however the minute we try to connect an additional wireless router the connection fails. We have even put the LAN from the second Wireless into the desktop and there is no connectivity.We have had a technician come to sort the problem, they advise that they have no explanation as to why the LAN works from the distance but the wireless does not. They have suggested that we need to cut the CAT5 half way and put an antenna up to connect the two routers.

The wireless router, which is a linksys E1200 is completely new. I setup the entire wireless and there was no problems on that front.The problem is the wireless connection. Even when I am within a few inches of the router, I couldn't even load a youtube video properly. It buffers every 2 seconds. But when I plug the cable into my computer, it works completely fine. The signal strength is excellent all the time.
I tried using inSSIDer to look for the number of connections within my area for the one with the least inteference and found that I'm already on the good one, or actually, all of them looked more or less the same. But I tried changing anyways from 1 to 6 to 11, and none of them made a difference.I then tried changing my Wireless Security to WPA2 Personal. Then I tried changing the Wireless Network Mode to Wireless-G Only instead of Mixed and the wireless speed increased.

Problem: My PS3 displays An Ethernet cable is not connected almost immediately after logging in. I am connected through a Linksys E2000 router. If I reset the cable modem, it will work for 10-15 minutes until it errors out again. If I plug the PS3 directly into the cable modem, it works fine. I'm really confused. I do not believe it is the router, as my computer is also connected to the router, and works fine. My Touchpad is connected wirelessly and also works fine. I do not believe it is the PS3, because it works fine if I plug it directly into the cable modem. I tried switching to wireless and it finds a lot of other signals (including mine), but I have the same problem if I choose wireless.I first had this problem with a launch PS3 and a Netgear router after almost three years of no problems.

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'm trying to setup a Canyon CN-FW514 wireless router through a Thomson modem.When I first started trying, I could get up the set-up screen on [URL] however this is as far as I got; the laptop said it had a very strong signal with the wireless connection, but I could not get any web pages to open (windows explorer couldn't detect any problems either). The Thomson modem works when I conect it to the laptop via the ethernet cable, but that's not much use to me trying to use the internet elsewhere in the house!I tried changing the IP address, subnet mask and gateway IP address on the set-up screen [URL] which seems to have been a big mistake; I now can't even get the set-up screen to appear.I've reset the internet options and have set everything to obtain the IP address automatically but am still having no luck.
