Restored router to factory default now internet is slower?

[rowlfe]

Reset it back to factory default settings and then configure it as your ISP told you the first time. It was mere LUCK that you did not hurt yourself when you made a change after the fact by not knowing what you were doing. You only THINK it made things better. There is no "DNS type" setting that I am aware of. All you can do is select whether you get the DNS information dynamically from your ISP (default) or you set the IP address manually from information provided by your ISP when you signed up. Maybe this is what you meant by STATIC. Your computer either gets it's IP address from the DHCP server in your router (IP addresses in the range of 192.168.X.X) or you manually set it yourself, which is what "static" means when referring to an IP address. Your ISP dynamically assigns you an IP address from a pool of IP addresses. When you log in to your account (via your router) your ISP checks if the IP address you used last time is available, and if it is, you get it back. If the old address is taken (assigned to someone else while you were offline), you get another from the pool. And THAT is what dynamic addressing is. A business will generally have a static address assigned so they can run their own servers and have a presence on the internet. DNS (Domain Name Service) is what connects a domain name with an IP address. With a dynamic address, you must update DNS each time it changes. A static address solves the problem of the changing dynamic IP address. The internet ONLY uses IP addresses to send data places. DNS is what makes it easy for us human types since we use common names instead of IP addresses. Without DNS, you would have to have the IP addresses of sites you want to visit. DNS is exactly like a telephone book with names (domains) and numbers (IP addresses) which you look up.

The ONLY changes you make from the factory default setting are to change the admin configuration password, add your ISP information that they tell you to add, such as your USER ID and PASSWORD, and if you use wireless, turn the wireless transmitter ON and add a wireless password (NOT the same as the admin password.). Write ALL of this information down and put it in an envelope and tape it to the router. NO further changes are needed unless directed by a network engineer from your ISP.

Now, for wireless access and the headaches... wireless suffers from "the party line effect" which is a general slowdown of THROUGHPUT. Throughput is the amount of data moved per unit time, which is a quantity. SPEED is a constant which depends on the radio frequencies used, and is a rate. SPEED equates to THROUGHPUT only when you are on a private link which is NOT shared and data only flows in one direction. When you share a line or have bidirectional flow, you divide throughput among all on the line, while speed stays the same. In effect, you time slice the data flow among all of the users. On wireless, there are two mechanisms at work that slow throughput. First, the wireless access point itself is a bottleneck. It has one transmitter, which means it can talk to only ONE user at a time. All other users are waiting and losing throughput the longer they have to wait for their turn. Second, interference. Each user including the access point, has what is in effect, a push to talk walkie talkie. When you want to talk, you listen and if the line is clear, you push to talk and send data. You then wait for a reply. No problem. Data moved. If the line is busy, you wait for the line to clear and THAT lowers your throughput since none of your data moves. When the line clears, you push to talk and send data. A minor hit on throughput because you waited for a short period of time. The big problem arises when more than one is waiting. When the line clears, both try to talk and they collide, interfere with each other and neither gets thorough. So not hearing a reply, you do it again (send the same data again), and you collide again, and again, and again until finally one of you hears the other key up and start talking and is forced to wait again for the line to clear. All of this is DEAD TIME with NO data moving, which hurts the throughput of ALL on the line. And THAT is the party line effect in a nutshell. Wireless is not alone in suffering from this, so too does cable broad band. Cable broadband uses higher frequencies and wire to carry the signals, but otherwise cable broadband and wireless are the same technology, a party line. All you can do to improve the throughput situation is use a cable instead of wireless access. You only have control over what happens on YOUR side of the router. Your ISP gets control over the rest of the world outside of your router. My recommendation is to dump wireless in favor of wire to your router and avoid the headache of the party line effect.
