We have a large area MAN provided by a local cable company. Each location has a cable modem that connects directly back to a central location, i.e. it doesn’t cross the internet, it is a private connection. Each out building shows shows up at the central location though a trunk fiber and each building is a different vlan. The issue is we are in the process of upgrading and merging our networks (there were two [...]Continue Reading »
I didn’t found the proper forum – so move the question if you find a better place for it. We have 10 houses scattered in the area 500 meters in diameter, and have a tiny DIY CATV network providing houses with 2 analog TV channels (don’t laugh it’s third world). We use cheap CATV signal boosters/line amplifiers at some intermediate houses to get the TV signal to the farthest houses. Now we want to setup [...]Continue Reading »
I am a web developer running a demo server at home. My site is accessible from Atlanta as well as via my local cellular network. However, both a webserver I have in Utah and a webserver of a service I need to interact with that is in California are unable to connect to my server. Communication goes through if I initiate the connection to the webservers. When I do a traceroute, the route ends at [...]Continue Reading »
We are in a semi-rural area, so our internet connection options are pretty limited. We currently pay about $500/month for a dedicated T1 line at 1.5/1.5 Mbps from the local ISP. In comparison, Comcast is offering a 16/2 Mbps “business” internet connection for $90/month. Other than raw speed and their SLAs, what metrics should I be comparing the two services on? I’ve heard people say that cable is not as secure as a dedicated T1 [...]Continue Reading »
This is the second one I’m trying, so it’s either me or something else is up. When I connect any of my LAN devices directly to our cable modem, the speeds are perfect. No latency, no packet loss and we reach or cable providers advertised up/down Mbit/s capacity. As soon as I put a wireless router (Linksys WRT54GL) into the mix, everything just goes to crap. I mean I can honestly still surf the web, [...]Continue Reading »
I have cable, and the modem only has 1 network plug-in. They said I could buy my own router if I wanted to hook up two computers to it. I have an IBM Turbo 16/4 Token-Ring PC Card 2, which was in the laptop when I bought it, and the laptop also has the typical network plug (not a PC Card). Is there a way I could run the laptop as a server, and plug [...]Continue Reading »
Does anyone have an idea of how many IP addresses max a DOCSIS 3 cable modem can support? I seem to get varying answers even from different people at our ISP. Thanks, Ryan I’m assuming you mean the number of public addresses that may be either assigned to the modem or routed? To my understanding, DOCSIS is Layer 2 and below. It shouldn’t impose any limitation on assigned IP addresses at all. In the same [...]Continue Reading »
My company currently has only a Covad T1 that connects the main office to the internet. This line is mainly for our billing office (located across the state) to connect to us for our Terminal Server. Our future plans for our main office include having a company E-Mail Server as well as a Web Site for employee access, applications, information, PR, etc. Our normal day to day internet access doesn’t include much besides a GPS [...]Continue Reading »
