Comcast Connection Keeps Dropping Often
Sep 11, 2012
I have had comcast for 4 years and for the last two years my comcast connection had been dropping. At the time I didn;t take it as a big deal because I have bad connection but not it's way too frequent to ignore. I have gotten a new router and exchanged a modem from comcast. Basically at a random time of the day internet just goes off. To fix it, I have to go up to the router and disconnect and reconnect the router. Even sometimes it doesn't fix the connection so now to fix the dropped internet everytime I do the following procedure: Unplug ethernet cable from modem --> Unplug the modem --> unplug the cable that connects the modem and a Y-extension for TV and internet
Motorola modem: (new one)
Software Version: SB5120-2.19.0.16-SCM00-NOSH
Hardware Version: 1
MIB Version: II
GUI Version: 1.0
VxWorks Version: 5.4
Cisco E-1200 v1 router (new one)

For those of you who are trying to connect your router to a Comcast modem, be sure to actually RESET the modem instead of just depowering it like it instructs you in the setup process. This should save a lot of trial and error. Also unmark the MAC address cloning like the Cisco connect software does, then just renew IP and it should connect just fine.

I have xfinity internet with a comcast rented modem connected to a personally owned belkin router. I can successfully connect to the internet directly from the modem or if I connect to the modem to the router and then to my computer via ethernet cable. I cannot for the life of me connect wirelessly with any devices. The router previously worked when it was hooked up to comcast internet, but it was moden->router->my router. When I connect wirelessly on my Windows 7 laptop, it says I connect and that there is internet access. But when I try to load a page it takes me direclty to this website: url.. Comcast says that it is my router that needs configuring properly with xfinity and wants to charge me $39 to provide this wonderful service.
Router: Belkin Model F6D4230-4 v1 with firmware F6D4230-4_WW_1.00.03
Modem: Comcast Model RCA DCM425

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 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.

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.

i recently purchased a D-link n300 DIR-632 (wireless router), i ran the setup wizard and it seems to work. HOWEVER. for some random reason the data transfer will cut out for around 30 seconds or so and all activity is halted. I have looked in the routers Settings however i am not comfortable with messing around with to many settings incase i completely screw up the network. Is there a setting that i have to change so that my network will run more fluently. It is a 300mbs data transfer and there is a maximum of 3 devices running from the network at any one time. I am trying to play online games and the network will lag and freeze the game causing it to crash and have to be restarted. ALSO i would like to note that this router is LAN enabled too. The main computer running on this network is connected by a LAN cable and is still having the same data issues as the wireless devices....

My lan conenction keeps dropping on my desktop, we have two other Pc's attached to the same router (bt business hub) and they are always working, however my Pc runing win7 64 bit says its connected to the router and assigns an ip but its not connected to the internet? ( until i do a restart)
Ive fixed the IP and DNS- still dropped reinstalled drivers for NIC- still dropped Restored machine back to a few months- still dropped, checked the cabling and changed- still dropped
I could understand this if it wasnt finding the router or IP and if the other PCs showed the same symptoms, however thats not the case and its reallt confusing.

I have a TG782T Thompson Gateway, and a few months back we had a lightning storm where it hit the ground fairly close. Ever since that storm, on a regular basis our DSL connection on the router keeps dropping out. Also the phone that we had at the time was shorted out and we had to buy a new one.

I have noticed a few times over the last month that my PC would not load pages due to connection problems. If I hover over the Network icon, it say that I am not joined to a network but within minutes, it reconnects itself. I use http://www.scan.co.uk/products/zyxel-pla-4201-500mbps-mini-powerline-adaptor-twin-pack power adapters and they "appear" to work well with good speeds as I download and game online alot. I have noticed that today the problem is really bad. It loses its connection every 5 or 10 minutes and then reconnects itself as if nothing has happened. I tried using my iphone on the wireless and it also seemed to have dropped out on connection. I have tried resetting my router too but with no joy

I keep dropping my internet connection.
I have a NetGear N600 Wireless Dual Band Router model WNDR3400 purchased 4/26/11.
I keep restarting it and it's ok for a little bit but intermittently keeps dropping and coming back. I am in San Diego on using Cox Cable as a service provider, I guess it could also be the modem??
how to troubleshoot to determine if it's the modem or the router?

Recently I have been having problems on my home Wi-Fi connection. Every so often, I drop my connection. It happens many times during the day, and it is really starting to annoy me.On the Wi-Fi connection, are 3 other laptops than mine connected to. About 3 months ago, the problem began for me, only recently have the others also gotten the problem. As we stand now, we are all craving for an explanation.

For the last couple of months we've been having problems keeping a connection to the internet. The green light turns red and everything loses connection while it cycles back on. I've tried everything I can think of and am at a total loss as to how to fix this.
The ISP has been out twice to check and replace all the lines and install a cat 5 line to no avail. I thought it might be an ip conflict dropping the connection so I assigned everything its own address and that didn't solve anything. I have a brand new netgear n300 router/modem that replaced the Actiontec one the ISP provided because I thought that might be failing, no change. The next thing I tried is to turn off and disconnect everything from the network except my laptop to see if it was a certain device causing the problems. It seemed to be going well for about an hour when I lost connection again. The next thing I tried is to hook it directly to the router and turn off the wireless to see if that worked any better, connection still dropped. When the guy was over here replacing the lines, he mentioned that he had just come from another house on our block having similar problems so now I'm thinking maybe they have to fix the lines on the poles. It seems to me that the most likely thing is that the connection is dropping from the ISP to the router, what I could try before I called them up to tell them the problem is definitely not on my end.

I'm looking to improve my connectivity,as the internet drops out a few times a day.Let me explain - I hope I'm correct in my assumptions.Every few hours, my PS3 will have a DNS error, and upon checking my iPhone, I notice that it's switched from wifi over to 3G and there seems to be a loss of connection. I cannot reconnect to the internet until I've restarted my router, or 'forgotten' and rejoined the network.
Additionally, we have an Apple TV, and connection drops out about 3 or 4 times every hour, which is very frustrating when trying to watch a movie.

I've had it for a little over a year and its always been really good with internet connection, strength-wise and speed, never dropping below 95% and just a Megabyte or two off from my corded computer. I have a high end d-link network card in two other computers as well and they each experience the same problem. So something is up with the router. Frequently, when I connect this specific computer to the internet, it drops wireless signal completely and won't connect for any computer for a couple minutes. Then suddenly, out of the blue i'll regain connection. Also, i used to always get a strong 35 Mbps on wireless, which I still do on corded, but now i only do on rare occasion. Most of the time i'm stuck at 12 or 14 and even more often, it drops to 1 or 2. Very unstable. I have reset it it multiple times, along with my modem, still same old problem persists...

My WOW internet connection keep dropping out. I recently went form AT&T dsl to Wow but as I surf my internect connection drops out. Could I have some software conflicts in my computer since I converted from At&t connection to WOW. I used a At&T Gateway 2 wire router before installing WOW. I don't have a router connect to WOW at this time. I am directly connected to their modem.

I changed my ISP (I don't know if that has anything to do with it).I have my network setup so I have a seperate modem (tp-link td-8616), which is connected to my router (asus wl-520gu) and do most of my computing from my computer (running Windows 7 64 Bit Home Premium, wired network). I had installed tomato firmware onto my router, which was working fine with my first ISP. I changed companies about a week ago, and noticed my connection kept being dropped. At first, I thought it was an issue with my ISP, so I called them up, and didn't find a solution.
Afterwards, I started doing some trouble shooting on my own, and noticed my modem was still connected (via the WAN LED, at least), even though my router disagreed. So, I tried connecting directly to my modem and my connection would be fine without any issue at all, so I thought I'd trouble shoot the router. I switched back to the factory asus firmware, connected it back to my modem, and after a while, it disconnected my LAN connection again. My router comes with this somewhat annoying interface that tells me the issue is "You have set the wrong dynamic or static IP address for your wl-520gu." So, I investigate that, and here is the setup:
My modem is statically 192.168.1.1 when I directly connect to it, so I left that setting alone.My router is also 192.168.1.1, but this was how tomato worked, so I'm not sure that this is the conflict, so I tried setting it to 192.168.1.2, which does not seem to fix the problem.My DHCP settings are set so connecting computers are 192.168.1.100-254, which should avoid the conflicts.

I'm with Virgin Media and the router they give is rubbish. The wifi connection kept dropping. So, I bridged the router to a Linksys router. The wifi is nice and stable now. However, when connected via eternet to the linksys router, I've noticed that my download speeds are very spiky. I used to get a flat 4MB/s download (I have 30 Meg internet). Now it spikes heavyly and I roughly get 2.5MB/s. I've turned the Virgin Media router (which is a netgear inside) into modem mode and when trying to connect directly to the virgin media router, I won't pick up a connection. I assume I can only connect directly to the Linksys.

I recently got a (new) Dell Inspiron 570 desktop. It didn't come with a wireless adapter, so I picked up a (new) TP-Link TL-WN781ND Wireless N PCIe adapter. Easy installation, worked immediately. Connection's not perfect, but I get 3 bars from across a house so it's about what I expected.Unfortunately, every little bit the connection drops. Sometimes it comes back within seconds, sometimes it lasts for several minutes; sometimes I won't notice it happening for hours, sometimes it drops every few seconds. There are two other computers on the network that don't suffer connection issues, and I've been able to test with my iPod that it's still connected at the same moment as my Dell is not.I tried updating the driver automatically, which oddly enough installed the driver for an Atheros AR9285, a different wireless adapter; and although everything seemed to still be working I gave it long enough to make sure the problem was still there and downloaded the correct driver from TP-Link's site, which didn't fix it either.

Recently been taking my Laptop installed with Win7 Pro to a Friends and was sharing his Wireless connection from Belkin ADSL2+ wireless router and notice that every now and again the wireless connection would drop out and the only way to regain a connection to the reset the router. My friends network has two laptops on it connected wirelessly with Windows XP home edition SP3, and a Desktop PC with XP also on connected to router Via Ethernet, also a Windows Home Server and XBOX 360 also connected by Ethernet, My friend since updated his laptop to Windows 7 Home Premium and is using the Wireless connection which now finds intermittent loss of connection which can only be restored by Resetting the Router. why a Router should lose connection just by connecting a Win7 laptop wirelessly or is there more to it than that.

My router at work is working fine, at least for LANing...as for its connection to the internet, it keeps dropping the connection.The router will be connected to the internet for say an hour or 2, sometimes more, and then it drops the connection. Usually a router restart(either from the web interface or by pressing the on/off button) fixes it, but only for a while.

The route is connected to that. Wirelessly, there are two laptops and sometimes an iPad and sometimes a Wii. Verizon DSL. I barely use my laptop during the week, but did notice some connection issues maybe Thursday and Friday nights. All day yesterday and today, as well. I will have a connection for maybe 5 minutes and then get errors loading webpages (and/or videos stopped). I will repair the connection and it will say everything is fine but it will not work, repair again or disconnect/reconnect(sometimes, several times) and then it works for 5 minutes or 20 minutes before the same thing happens. The other laptop is having the same problems. What I have tried so far: restarting the PC, both laptops, the router, and the modem. Resetting the modem. I have not moved any furniture or anything that would cause interference. I am worried because I have been trying to make more money and started at this site called Treasure Trooper which seemed okay-surveys and the like. There were a few pay-to-download things I downloaded but did not run. Avira found a trojan and I deleted it (not sure if the two are related, but I can not think of anything else I have downloaded or installed in the past month or so).The old PC is off; the Wii is on but probably only maintains a small connection. The iPad and other laptop are not mine, but if either is on, they probably have little to no activity right now since the user is away.

My internet connection keeps dropping when using my router. I will have internet connection for a few hours and then it will drop. I thought it was a bad router (I had a Netgear N300 that is about 2 or 3 years old) so I bought a new Cisco Linksys EA2700 N600 router and the same thing happens. I can connect to the internet through just the modem and it works fine. Is is just a setting or something? BTW, I have an Arris cable modem that is several years old and my ISP is Suddenlink, and am running Windows XP Professional SP3.

My internet has never had many issues, but since 2 days ago it has been frequently dropping the connection every so often (maybe every 10-30 minutes). The speed jumps all over the place, reaching as high as 2mb/s and then dumping down to 0.14 kbps while going up and down. I am not sure what the issue is. I am running wirelessly on my desktop using a D-Link DWA-130 adapter.

I have installed the netgear N900 dual band which is 99� and is working fine on 2.45ghz because I have a belkin g range extender as my house is very long. So everything is working and my computer works but every so often the Internet drops so the modem needs turned on and off to get back on the Internet even though my computer says its connected but not loading any pages. It works fine for a while then sometimes drops, it works fine until I use my Mac books or iMac but works fine with iPhones? What can I do ?

My old WRT54G V8 router has been acting up lately. It keep dropping the connection out of the blue. Sometimes I'd be browsing the Internet when the router's signal vanishes completely, it disappears from the list of available wireless networks on not just my computer, but my smartphone and all other devices in the household! Other times I keep connected to the network but there's no access to the Internet. Everything seems fine on the ISP's part, I can connect just fine directly from my modem, so I'm certain the problem is with the router. Besides, these problems are solved by just power cycling the router.

But i can still navigate around on a computer. So i have a gateway laptop, and a cisco router in my parent bedroom. They have computer's connected into it with a wired connection. My laptop is a wireless one. The connection will drop roughly 10 times a day. And the odd thing is , to get the connection to show back up on my wireless connection lists, i need to restart the router or it doesnt show. Its not a problem with signal strength, and obviously no problem with the router as my parent's stay connected during this. I called my ISP, they told me to call gateway. I did , and after that, i will never in my life associate with anything gateway ever, ever , again. I'm sure its a setting or software issue

I have two different friends that are having problems with their printers which are connected to their home network. One has an Lexmark printer wired to their router and running Windows Vista on a laptop. The other has an HP printer connected to the network wirelessly and the laptop is running Windows 7.
In both cases, they are setup to use DHCP. When first setup and the printer software was installed, everything worked fine. Now they each get a message showing 'offline' when they try to print. I went to each of their houses, downloaded and installed the latest printer software and they were printing again. After a short time, the same problem surfaces.

I have a wireless Motorola modem that is hardwired to a computer that is usually off. This modem services 4 other computers in the house wirelessly and all experience the same frequent connection drops regardless of connection quality. I've had problems with this modem for as long as I can remember but it never bothered me because the problems were too far and few between; now, the connection has progressed to dropping within minutes of use.When the connection is dropped I cannot access my modem (plugging the ip address 192.168.0.1 into my web browser)The connection stays acceptable for a while after resetting but always reverts back to being a piece of crap. The connection drops most frequently when under heavy load i.e. steam downloading a game at my connection's full capacity, just only more frequently. The connection will still drop within the hour if I'm downloading anything or not.
I've tried rerouting the wireless modem into another wireless router before but it caused me new problems.Before this all started within last week, I contracted some spyware that redirected Google search links and also killed my connection frequently along with terrible slowdowns. I gave up trying to clean the system and reformatted but my internet connection still drops and it's now affecting all computers that connect to this modem. [code]
