ADSL Modem/Router

I have to ISP coming in and I have two different technical setups for them, but both of them are the same idea. An ADSL modem which is a attached to a router which handles the network. For past couple of weeks my internet from Qnet has been acting up, I have done pretty much every possible conceivable solution to try and remedy this but to no avail. I have decided to do some testing with my modem, I have feeling that its life has come to an end after 6 years of good service, its a Thompson ADSL Modem but I can’t really do any configuration on it when I try to access it, so I wanted to replace it. Called my Qnet and all they offer is the Linksys ADSL which was crap from Kems, I asked for a Cisco modem but they said that it is only for corporate customers and they don’t have that in stock.

I’m judging these modems by a few of the points listed below, the main point is stability and no issues then I go on to other testing.

Key Points for successful modem:

  • Faster Connection, with the newer modems surfing is substantially faster due to the better architecture, a Cisco modem is much more stable and faster the a Linksys modem and I have tried that first hand
  • FTP and VPN access without any issues
  • Extra features such a Port Forwarding, VPN configurable, Black or White Listing IPs & MAC addresses, DynDNS, and Wireless options

I have taken the options into my own hands, and after reading up online I decided to do some testing on affordable regular ADSL modems to post it up later. All the below have decent reviews and had their own problems and what they were good at, I’m going to test it to my preferences and see what I come up with as a winner.

Two Tier Solution

I had the Belkin ADSL which worked all nice and dandy for only a few days before funky things started happening. I wanted a one box solution which I could use for all my needs instead I got another bunch of headaches. If I left my desktop for more then a day it wouldn’t be able to access the internet, I would have to manually restart the router. If a laptop was put into standby I wouldn’t be able to connect to the wireless connection, again I would have to reboot the router. Another thing which really bothered me was that for some reason the connection was a bit slow whenever I did a traceroute there was always a long delay with a multiple websites, so after going through this hell for a couple of weeks I went back to my old solution.

I brought back the Cisco Modem and D-Link Router, as soon as I plugged it everything was back to normal. Browsing felt very fast and stable, I was downloading and browsing faster then before. Even when I was sharing the connection with the main PC I was having issues with it hanging. Now with this solution its working perfectly, my only gripe is that I can’t really do any configurations with the Cisco Modem, if I try anything from the console I will probably crash it, I can’t even access its web based interface, until I find somebody that can I will leave things as is.

ADSL Modem Switch

I have been thinking about switching my current ADSL modem to something simpler. I had a problem with the ADSL Linksys modem from Zaijil, it kept disconnecting, so I upgraded it to a Cisco ADSL Modem, and used the D-Link Router as the DHCP and main connection of that network.

The one problem I am facing is that I am unable to pass through the public IP Address from the Cisco Modem to the D-Link Modem. I want to access the servers through the DYDNS website, and haven’t been able to due to this hiccup.

I have recently gotten my hands on a Belkin ADSL Modem, with decent reviews. So I am planning on using it as the main connection and DHCP modem for the network, and I can use DYDNS with this modem to access my network. The one thing about the Cisco modem is that it hasn’t had any problem what so ever since installing it, the only problem I have with it is that you have to have a Cisco Certificate to even think of configuring the damn thing.

After plugging the telephone cable in the Belkin ADSL modem, I called KEMS to get the information, turns out they login through PPoA and not PPoE, and I got the VPI/VI numbers needed. As soon as that was done, the router restarted and within a minute it was connected to the internet. Of course during configuration it was wired to the laptop. After that I disconnected the D-Link Router which is performed perfectly, finally removed the Netgear Dual Wan Router which has operated as a heat sink for me and nothing else, then I disconnected the Cisco ADSL modem. One thing for sure is that the Cisco modem is extremely dependable, but difficult to manage for a layman such as myself. I was having a few problems connecting the wireless but after restarting it, the laptop connected fine. I was hoping that I didn’t need to restart the machines, but I knew I would. So I restarted the WHS servers, but first I shut them down, cleaned them out with a dust blow which turned into its out little mini dust storm in the room, connected the main WHS server to the UPS and powered it back up correctly. After going through this whole process which took about two hours to make sure everything is connected, I was satisfied with the results.

Network Merge

I’m getting closer and closer to getting the network setup the way I want. I currently just received the Netgear FVS336G which will perform as an load balancing for both my ISPs.

The problem I’m having with my ADSL routers is that they won’t be able to be able to sustain this connections for a long time, and I need to restart them every once in a while, and if they are under pressure then they hang. I have a Thompson from Qnet, and Linksys from Kems but I needed to upgrade them. Going on a recommendation from a friend I am trying to find two Cisco 837 ADSL routers to use which will perform perfectly for my needs.
