Cisco WAN :: 3930 Comcast EDI Ethernet Dedicated Internet Setup
Dec 22, 2012
We have purchased Comcast fiber EDI services. They run a fiber to our office and connect to a Ciena 3930 switch. The speed we have is 30 down and use for Internet. Comcast provide a /30 and /29 address. Do I need an additional router to route /30 to /29? I only have a PIX firewall.
I work in small office with four users and we use Comcast as our ISP. A separate room from the office has our cable modem. The cable modem has a Ethernet cable going to a WRT54G WAN Port. The WRT54G is not being used as a wireless router.Coming from the LAN ports is a Ethernet cable going to a Netgear switch.The office has Ethernet ports and one of them is hooked up to a Netgear WDNR3700 wireless router. All users are utilize the wireless network to get online. There IP Address is 10.0.x.x. When I use a Ethernet cable to a computer my IP Address is 192.168.x.x.
What needs to be done so the IP Addresses of the wireless network and wired network use the same IP Address range?
Just got home from the Comcast store with a $7 rented modem just to last me until I do research and purchase one. I realize that this modem has only one Ethernet port with no WiFi support so I have another PC and a laptop sitting idle because there's no internet access. Did a quick search using Comcast's authorized modem's list and all of them only have a single Ethernet port and no WiFi. Is there a modem with multiple Ethernet ports with built in WiFi? I am getting almost 20mbps with a download speed of 4mb/s which is a HUGE improvement over my ATT DSL service that I've had since forever at 3mbps with a download speed of 300kb/s. I have no idea what technical specifications to look for in a cable modem to get 100% of full potential speed from my service without disconnects or other various problems.
I have a ATT U-Verse router sitting here right now, I am wondering if I can somehow connect it to my Comcast modem. I tried to connect the ATT router into Comcast modem via Ethernet cable, but I couldn't get past the "Your DSL service is unavailable" in the browser, but in my desktop system tray, it shows I am connected to the internet. If I could use this router, I would rather spend money on a modem instead of getting a combo.
I have been using my Sony Locationfree tv with Direct TV and now have Comcast and it doesn't work. The installer said i have to change the tv setting to channel 3, but i haven't been able to program the remote he gave me. I thought the device was just a wireless monitor, so i don't see how it has a channel to change
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 have an ASA 5510 with a second internet connection on its way. I would like to have one internet connection dedicated to my Site-to-Site VPN traffic and the other left to handle public internet traffic. I know I can do this with a static route but I noticed today the "tunneled" option. How exactly does the tunneled option work and would it work better for my specific situation?
We have an ASA5510 and we're currently using 1 internet connection to handle our site-to-site VPN connection and our internet traffic. We have a second internet connection on hand. What we would like to do it use BOTH internet connections: (1) will be dedicated to our VPN connection, (1) will be handling all our internet traffic. How can we get this setup? We're running Software Version 8.4(1)
My mom just got comcast internet for the restaurant but I can't log in to it with my laptop because i dont know the network security key i looked under the smcd3g-ccr router but no network key only find theses labels, Model Name, Smc P/N, P/N, S/W Rev, H/W Rev, R/F Mac, Wan Mac, S/N, and Iden:1033, But no network key or wep label. I tried logging in the router with default gateway 10.1.10.1 and entered cusadmin for login and highspeed for pass and in the router there is no wireless tab, NONE, so I can't find the ssid or wep key ill show you a picture for the homepage [url]...
I have Comcast 20Mbps internet. When I'm on the Mac partition of my computer, I get 15Mbps download and a ping of less than 10 on speedtest.net. When I'm on my Windows partition, I get a ping of around 250 with a download speed of 1.5Mbps. I read posts where people said disabling their firewall worked, so I disabled mine and it made no difference.
Recently I have noticed my internet get slow. I use a comcast cable internet connection that is directly connected to my dlink DR 655. I use the megapath internet speed test [URL] when testing my internet speed. Have a laptop that is usually on wireless and an XP workstation that is connected to the 655 directly with static IP.
I would be browsing the internet and all the sudden the internet would get really slow. This would happen on both my desktop and the laptop and my speed test on both machines would be around .3 Mbps. When this happens I would go and connect the laptop with the ethernet pot directly to the modem. Of course a reboot of the modem has to occur before a connection can be made so once I do that all the sudden my internet is back up to par (12 Mbps). I go ahead and put my network back to the way it was and it all goes back up to 12 Mbps. I have called comcast several times and they are telling me it my router.
This picture shows a snapshot of some windows from the laptop. The CMD ipconfig on the bottom left shows the laptop network settings when connected directly to the modem. The CMD ipconfig on the upper left is the network settings when connected to the router. The web page on the right shows the WAN network settings when the 655 is connected to the cable modem.
Notice the DNS servers, they are different when the 655 is connected to the modem versus when the laptop is connected to the modem. Could this be part of my problem? I have not seen were I can manually change 655 DNS entries ... is there a way to do this? Or should I not even be worried about it?
When we got broadband through our cable provider (Comcast), we were sold a single user license even though we were explicitly connecting two computers.Upgrading to a multi-user subscription (for up to 5 connections) solved that.I'm currently trying to configure 4 computers to connect. I have noticed that if a configuration for one has WPA and another has WPA-2 they will bump.This may be true for differences in WEP-keys, TKIP setting, etc. If you do new configurations, the settings may revert each time to a default, which you may not notice.Keeping the network settings matched may work. Using a portable memory device to run a saved configuration on each machine can improve their synchronization.
We have Comast internet using an Arris modem and have a Netgear wireless router. We have our modem hooked up to a desktop computer that we don't even use. We have three laptops that we us with our wireless.Comcast has told us that we have to have the modem hooked up to the desktop for the internet to work.what do people do who have only a laptop and have wireless internet in their house?Is there anyway to get rid of the desktop and have the modem hooked directly to the cable and router?
I hav a laptop conecteted to the internet with comcast service and a netgear wireless router that works fine. but bought a desktop and when i hook it to the router i get no internet. im running windows 7 ultimate on both machines. i am gettin a thing saying unidentified network in my network settings and i called comcast whent through resetting the modem and router with them and nothing then they tell me i have to pay them to run another machine of of my router this is ridiculas i have the machine pluged into the port on the router with anethernet cable everything is hooked up right i know this im pretty computer savy as ive built many machines in the past.
I just got installed a business class internet service installed. Got the 25/5 line and when I perform the speed tests I get well above that with the speed boost on the lines.When I am downloading large files I am getting a constant 22-25 down and when I am uploading files I get the 5 up.... But I can't do both at the same time.What happens if my uploads kill my download speed so if I am uploading a file and taking up my 5 up it makes my download speeds about 2-3.. Comcast is saying that this is how the network works and I just don't want to accept that at this time as I have other internet providers that don't work this way and I get a true up/down at the same time. Unfortunately at this location that I am dealing with Comcast is the only choice.
My neighbor is using my Belkin Router the basic one and has comcast. We both use his internet and have had no problems until the past 3 days. He just got the home phone service from comcast and the phone line is setup through the modem. Ever since comcast came to his apartment and set this up the home phone service to his modem the router is connected but there is no internet access. What is going on and how can I fix this. He has an HP with windows Vista and I have a Toshiba Satellite L675 that has Windows 7 Home premium edition on it.
I have a problem with my E3200 that has happened at least 4 times since I first purchased, installed and configured it. Initially I thought it might be something with Comcast, but a) I never had the problem with my Linksys WRT54G router and b) It seems I can now duplicate the issue by saving a config file and restoring it.The specific issue appears to be somewhat random. At some point the connection to the Internet simply stops for no apparent reason. I am able to ping the router and connect to it. I am also able to drop and renew connections to the cable modem successfully. Furthermore, I can ping my network side of the router, as well as the external address handed to my router by the cable modem, and the cable modem gateway address, but still no connection to the Internet.The only solution to my problem has been to restore the factory defaults to the router and reconfigure it from scratch, which does seem to fix the issue for a time until it occurs again. FYI, I do not use the Cisco connect software because I have several custom port and QOS configs that are necessary for an IP Phone and other hardware on my network.
I just recently purchased comcast internet today and self installation kit that came with the modem and all..... got it all set up no problems activated did speed test directly from cable modem to laptop computer wired and was getting 10mbps down and 3mbps up well went out and bought a linksys e900 wireless router.... connected it no problems... however my laptop wireless and phones connected to the router with speedtest is only getting 300kbps down average!!! but the upload is still 3mbps.
I recently switched from a DSL ISP (Earthlink, Zyxel modem configured as a bridge, pppoE connect) to a cable ISP (Comcast, Arris cable modem, dhcp connect). Basically PC --> DIR615-->Cable modem-->Internets. With the old DSL the Internet activity LED (green, looks triangular) on the DIR615 blinked only when internet activity occurred. With the new Comcast connection it blinks non-stop about 5 times a second! Even if the PC is turned off it blinks. It stops blinking if I disconnect the ethernet cable between router and modem. The connection itself is fine, but if the DIR615 is doing something it should not be doing it might slow the connection down a bit, (or burn something out prematurely?)FYI, the Arris cable modem does not seem to be a router. It takes a cable connection from outside and provides a single ethernet cable and 2 (voice) telephone cables to the house.
Hard wired network (15 workstations.) I had a dsl modem connected to my network switch and linksys wrt54gs router connected to that modem. All hard wired workstations had internet access AND there was a wireless internet connection. With any wifi device I could access the internet.I switched from dsl to comcast. All hard wired work stations still have internet. but when I plug my wireless router into the modem (comcast business IP gateway) there is no wireless internet connection. The hard wired workstations can still get online and there IS a wireless network, but it does not allow internet access (page cannot be found etc.)
Comcast says it absolutely should work. Linksys says it requires simple reconfig of router settings (reset router, clone mac address.) I have read knowledge base articles from linksys and followed each step. The lan ports of the modem are all working if I connect to them directly with a laptop and cable. I have reset router multiple times, cloned mac address, dhcp release/renew.
My physical connections are correct. In the router set up utility, I can see the mac adrdress and ip address but can't tell if the IP is from the modem or the router. Default gateway is always 192.168.1.1 in the router AND in any workstation ipconfig screen. Ip addresses are 192.168.1.xx in ipconfig at any workstation AND in the router set up status.
I cannot access internet via router even if plugged directly into it. It is as if the router is not getting the correct information from the modem. However, it worked perfectly with the DSL modem the day before we changed.My workstations are all hard wired and work. I simply want to have Wi-Fi also... for phones and laptops w wireless etc.
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 was able to install the RV042 router to my ATT DSL line (WAN1 port-INTERNET) and it gets an external IP address automatically and the Internet works. When I connect my Comcast Internet to WAN2 port INTERNTE/DMZ) it doesn't get an IP address. and the Internet goes down and the WAN2 port ip address says 0.0.0.0.I've tried releasing/ renewing and it still says 0.0.0.0.Everything else is set as the default.
my house has 4 ports in each room, 2 coaxial, 1 for the net, and one for a TV, and there's a phone jack and a Cat5e Ethernet port. From what I have learned, all my ports lead up to a "closet", and I have found it. It has all the connections for the LAN, and everything else. I am confused on what to do next. I see that there are blue Ethernet cords connected to the ports on one side, and that they are not connected to anything on the other. I thought I had to buy a switch for all these ports, and I haven't done so yet. where am I supposed to connect the modem to the internet. It is currently connected to the internet coaxial port, which it then connect to the VoIP switch, and is then connected to everything else. Where is the coaxial port that I have to plug it in to, and what is it labeled?.
I'm trying to get a DS lite connected to my university's wifi, which I learned doesn't broadcast a Wireless-b signal, which a DS needs to connect. Can I setup a my own router connected to an ethernet port, configure it to boardcast wireless-b and get on wifi through that? I asked another forum which said yes, but I want to make sure before I buy anything.
OK i'm re-organising my network setup, most of my devices in my room are hard wired through Ethernet but some devices in the house need to run wireless.Currently i am running a super hub that has been configured into just modem only and a wireless router that gives wireless and hard wires up to 4 devices. Im wanting something that can be mounted out the way like an Ethernet switch but give it wireless accessibility too. I see you can buy access points to connect to your Ethernet switch device but will it give ample wireless connectivity if im running 4+ hardwired devices?I have recently been upgraded from 30Mbps to 60Mbps, this is fed from cable connection to the modem.
I have been doing network and computer work for a small public library which will soon be needing to change internet providers. Our planned route will be to have a fiber connection directly from our local ISP, but we need to figure out the best network hardware to accommodate this network connection.We currently have two HP 1810-24G switches connected to a Sonicwall TZ100 firewall as the primary router. The firewall/router connects to the internet with Cat6 connected to a fiber optic media converter. The media converter is on lease from the current internet provider so it will be gone.Our new ISP has said that they can provide a fiber connection in our building to an SFP port termination, which is their recommendation. Ideally, this would be an SFP port in a router or firewall. However, there seems to be very few options for routers with SFP and they're all incredibly expensive compared to a network switch with SFP. While I imagine we could just terminate the fiber optic connection into a cheaper switch with SFP and connect to that with the firewall, our network is further complicated in that we have a CISCO LifeSize video conferencing system which ideally runs best without running directly through the firewall, which can cause some lag and glitches in the signal it seems. I don't believe it's possible to have the router WAN interface connect through to the ISP with a static IP and PPPoE sign on as well as another network devices using the PPPoE and a separate static IP address, am I correct?Have I just over-complicated this network issue, and everything should just be run behind the existing firewall, or should I be able to find a different firewall/router or switch that can connect with SFP to the ISP?
I currently have CenturyLink (Qwest) DSL (12Mbps/896Kbps) and Comcast Cable (12Mbps/2Mbps) going into a Cisco RV08. I redirected all DNS traffic to the DSL line as an experiment with no decrease in web browsing speed. e are rural and speeds fluctuate considerably during the day. It seems like it's more of a response issue than a bandwidth issue. I would like to order a 2Mbps dedicated line from Comcast to use for DNS and VOIP traffic only, the DNS resolution times should be faster on that connection. There would be several tenants in this building using it for that purpose. The secondary purpose of this line would be for backup internet connectivity
My first time programming a Cisco ASA - Anyways I''m trying to setup up Ethernet 0/6 to be a DMZ Connection When I add port 0/6 to DMZ it gives me an error saying "The IP Address X.X.X.X /Subnet Mask cannot overlap the subnet of interface outside"So my question is I have an outside connection already configured - How can I make a DMZ connection with the same subnet mask with a different IP?
