My internet is slow for 2.4ghz

kenghtt · Sep 28, 2014

I don't quite understand why this is happening but I have a netgear 600db router. My internet speed should be around 30mb download and 5mb upload.
I currently have 2.4ghz and 5.0ghz set up.
When i use the internet, my 2.4ghz is super slow...feels like dial up.

I went to speedtest.com and i tested both connection.
My 5.0ghz connection had speed of 32mbps download and 4upload..
while my 2.4ghz only had 1.3mbps...
its so slow that it cant even finish to get the upload speed.

Does anyone know why its so slow for the 2.4?

http://kb.netgear.com/app/answers/detail/a_id/24246/~/should-i-use-the-2.4-ghz-or-5-ghz-wireless-band%3F This should answer ur question.

"The major difference between 2.4GHz and 5GHz is the speed of data transmission, also called bandwidth. Higher radio frequencies allow faster data transmission, so 5GHz allows much faster network connections than 2.4GHz. If you want to use high-bandwidth applications like streaming video, over your wireless network, 5GHz is by far the better choice.".

But the down side of higher frequencies is they don't go around objects as much and need better line of sight.

Its so slow though...what's the point of having 2.4ghz if its that slow. I know that 5.0ghz is suppose to be much faster but with shorter bandwidth. So should I just remove 2.4ghz all together? Should i go back to my router settings and just remove it if its that slow?

Yea dont bother with 2.4Ghz unless you have a laptop and require wireless network and if your using laptop far away, or share internet with tenants or something.

If we ignore stuff like 802.11ac 2.4g and 5g have EXACTLY the same speed of transmission. Both use exactly the same 802.11n encoding and both use the same 20mhz or 40mhz of bandwidth. The transmission power allowed by the government is exactly the same.

The main difference is 5g in absorb more easily by the air and walls so it tend to not have as much coverage. When you have no competition for bandwidth the 2.4g signal will many time give more total throughput at the same distance.

The key problem is there is massive competition for bandwidth on the 2.4g band. It is highly likely you have neighbors using 2.4g wireless routers. Since there is only a total of 60mhz of bandwidth and many people try to use 40mhz it ends up everyone stomps all over each other and pretty much nobody gets much at all.

5g has much more total bandwidth...ie channels so it reduces the amount of competition. Because 5g is absorbed by walls easier this too work in your favor to a point. The signal from neighbors has more trouble getting into your house to interfere with your signal. So if you can get strong signal on 5g from your router it should be less susceptible to interference than 2.4g.

There is no way to predict which is better in any particular location. All you can do is keep trying and see what combination works best.

Still the 5g trick will only work for a period of time as more and more people are getting dual band equipment and since 802.11ac only runs on 5g and is a huge pig when it comes to bandwidth it won't be long before we have the exact same issue on 5g as we do on 2.4g. The newest 802.11ac routers to be release likely early next year allow a single person to use ALL the 5g channels at the same time. This will causes massive problems especially if multiple people attempt to run it this way.

Thankyou everyone for your input!

I'm going to choose bill001g as I feel he answered my question the best.
