How to make your DSL connection speed faster or more stable.
This is part of the Howto section on DSL
No matter what your connection speed to the Internet, your Internet Service Provider has either given you or you have purchased a DSL Router or a network bridge. These units have network information stored in their memory. The are actually network appliances that work very much the same as a pc works.
The contain the information that is needed to connect to the Internet and they provide the path or route information.
If you are experiencing unexplained speed degradation that comes and goes or your connection speed is not what it should be. The solution may be as simple as bad power.
Although you may not perceive a power problem, electronic equipment is much more susceptible to these issues. If there are fluxuations of voltage in your building, your DSL router or bridge may get stuck and need to be re-started. In other instances, the unit may just begin to have corrupt data and you will see your connection speed go down.
All routers and bridges should always be connected to something that is going to clean up your incomming power.
Unfortunately, the common person will think that they have already done this by plugging the unit into a power strip that has surge suppression protection. Although surge surpression is important to avoid damage to equipement, it actually does not help with the problem being discussed here.
You need to find a unit that provides Automatic Voltage Regulation (AVR) at the least. AVR will try to maintain a stable voltage to your router, switch, hub and/or bridge. All units are not alike, depending on what type of equipement you own and how sensitive it is to power issue will determine what type of unit you should purchase.
It is actually possible to have an Uninteruptable Power Supply (UPS)
that is not able to provide the proper protection to prevent your Internet connection from being unstable because of the amount of time it takes to react to the situation. Any unit that takes longer than 4 miliseconds to react will most likely do nothing to help.
The shorter the reaction time the better. Unfortuantely the shorter the reaction time, the more expensive the unit as well.
The ideal unit to protect your Internet connection and networking equipment would be a UPS that supplies the equipment connected to it from the battery at all times. The battery would and is continuously being recharged as long a the unit is plugged in and there is electrical power being supplied. These types of units have no reaction time at all since they are already on battery power. They are of course the most expensive.
Units we have tested and suggest:
APC BR900 Backup UPS
APC BR1200 Backup UPS XL
APC BR1500 Backup UPS XS
APC SC620 Smart UPS
Any of the above units should stablize and improve your Internet connection greatly if you are having power issues. Remember, you may not even be able to tell if there is a power issue. Installing a UPS or an AVR will greatly improve your Internet connection.
This is especially true if you use an application that sends great deals of data over a long period of time.
Connection instablity could make these application not perform properly or appear to be frozen.
The only way to be sure if there is no power problem is to make sure there is none by installing a UPS with AVR.
