SMC 8014 Speed Issues and Interface
Hopefully someone has some help. Using an SMC 8014 to a 10 meg Dlink hub to 2 24 port 3comm switches. Speeds start out great for a period of time. Then randomly speeds throttle down to about 468k up and down, and the GUID of the gateway is not accessible it will say "Document Error: Data Follows cant get memory". The only fix to this problem is to power cycle the modem and it works again for a brief period of time. Any ideas would be great

I've been having the same issue with a setup thats a bit different. I have the SMC8014 connected to 1 20port dlink switch and to 1dlink 8port switch. the 20port has a netgear wireless router connected to it. The problem just started a few weeks ago. Comcast CS hasnt been any help. They replaced the gateway and still nothing. Powering off the gateaway usually does the job, but after a few hours im locked out of the gateway again. Ive tried rewiring so the netgear is directly connected to the gateway instead of the 20port dlink switch and gave the router a static IP and the damn thing still lockes me out and speeds decrease from 3MBPS to 300-500KBPS. Ive tried searching all over the web and everyone has different opinions about it, but nothing seems to work for me here. Hopefully someone here has a better suggestions....

Im replying to my own post..... so comcast finally replaced the SMC8014. Same problem!! Now im convinced that it's the setup. Maybe the netgear wireless router (connected to a 20port dlink switch?) ive tried connecting it directly to the gateway and it did the same thing. Could it just be the wireless router is faulty (but how, if its worked for so long w/o a problem)?? Maybe one of the 2 dlink switches?? the 8port? 20port?? I'll post back when I test it out different ways...

I am having the same issue. Already went through 2 gateways and getting a third tomorrow. I have a 24 port Dell Gig switch connected to two ports on the gateway, both on different VLAN's for internal and DMZ. I think these devices needed more testing before being released. Does anyone know of an alternative hardware for Comcast Business? Support is completely useless and having my email and web servers down all the time is just unacceptable. It does seem to happen a lot more if I am doing a lot of downloads. (Pulling 7 DVD's from Microsoft as I type this and had to power cycle about once every 2 hours)

Right after I got the 8014 installed we started having problems. Intermittent resets, loss of connection, DHCP stops. It's a very simple setup, plugged directly into the SMC device. As soon as I started getting a lot of traffic it shuts down, and won't recognize the NIC that was generating the traffic (on any router port) for 20-30 minutes. Tried different NIC's and Cables. Trouble is that it makes it look like I have a faulty NIC. Comcast is coming tomorrow...

I've had the exact same problem since November of 09. We had the original smc 8014 working for over a year with no problems, then all hell broke loose. It started loosing internet connection, no longer able to login do the gui with a direct connection to the modem, the modem stops issuing dhcp leases and Comcast says the signal looks fine on their end. The same issue happens even if none of my switches or other routers are connected just a plain old laptop with a direct connection and nothing else.
They have done all kind of trouble shooting. First checked the signal quality and strength to the modem, every thing is within spec. Second, they replaced the modem. It worked for about 5 days, then same exact issues. Third, replaced with another modem. While the tech was still on site the modem started randomly resetting. I waited it out and it lasted 12 hours and its now doing it again. I really don't know what to do now but leave comcast and go an alternate route.
I should also point out that getting anyone at comcast to help is really frustrating. The techs didn't even know the password for the router! I had to log them in. They also kept suggesting to me that a router reset is standard procedure! I understand that from a troubleshooting standpoint, but come on! The fact that a router reset fixes the problem while the tech is on site, does not mean they fixed the problem.
Sorry for the rant, but i'm not sure what else to do at this point. At least I know now that i'm not the only one with this problem.
