How can i get the highest possible Internet speed/dl speed?

Q. I have wlan connection with a nominal transfer rate of 54 MBit/s. Internetfrog etc. say that my dl speed is abt. 1.8 MBit/s. How can i get the most out of my connection? Or else, what do i have to change to get the highest possible speed? Thanks for any response!

A. go to speedtest.net get an accurate speed - and then make sure all your phone extensions have line filters - there is no large amounts of excess cable and make sure all connections are secure, also make sure there is no interference from microwaves other wifi networks or wireless baby monitors


How can i make WIFI go faster because it always seems to go slow?
Q.

A. Wireless internet is typically slower than wired.

Try to minimize sources of potential interference such as radios, baby monitors and cell phones as these can all lead to signal attenuation. Other then that you can upgrade your wireless access point or your NIC (N+ is the current leading technology. Or even move closer to the access point.


What is the frequency transmission of wifi ?
Q.

A. There are two different frequencies. The 2.4GHZ and the more modern less well supported 5GHZ.
All routers and mobiles etc can use the 13/14 channels available on the older 2.4GHZ frequency whilst some newer devices that support IEEE 802.11n specification can also use the 5GHZ frequency. In many built aup areas where there are a lot of wifi enabled computers using the more widely supported 2.4GHZ frequency you can get signal problems, also cross over interference from other wifi devices that use the same frequency range, eg baby monitors.
Some, but not all, of the latest IEEE 802.11n capable routers can use both frequencies simultaneously and as the 5GHZ frequency is less crowded, a better signal can be acheived.
2.4GHZ does have a longer range though.


What is the difference between 5.8 gighrtz and 6.0 gighrtz?
Q. What is the difference between a phone that has 5.8 giga hertz and 6.0 giga hertz?

A. I think that you are asking in relation to cordless phones... In which case, there are NO 6.0Ghz cordless phones... there is however DECT 6.0 phones, which operate in the 1.9Ghz range...

When it comes to radio frequencies, the lower the frequency, the further the range, as long as all other factors remain the same. 900Mhz phones would in theory have the best range, however, they operate at lower transmitting power then other cordless phones.

From best (range, battery life, etc) to worse:

DECT 1.9Ghz - best range, least interference, unlicensed radio spectrum dedicated strictly for cordless telephones.

2.4 Ghz - next best range, however this unlicensed radio spectrum is crowded with wifi, wireless video cameras, and various other wireless consumer devices, and therefore subject to increased interference.

5.8Ghz - unlicensed radio spectrum, not as crowded as 2.4Ghz but also may contain other consumer electronics. range is limited compared to 2.4Ghz and DECT phones.

900Mhz - no security, can be listened in on any radio scanner ("police scanner") unless equipped with DSS. least range of all currently available cordless phones. Many consumer electronics such as baby monitors, and wireless intercom and doorbell systems, and garage door openers operate within this frequency range.

1st Gen cordless phones (aprox 48Mhz) - poorest range, no security, can be listened in on with a radio scanner, also shares unlicensed frequencies with baby monitors. Limited frequencies. No longer commercially available, however some (very few) of these phones are still in use.
