2.4ghz Slow

Hi,

I had a new 500mb install today with 2.4ghz and 5ghz split.

The 5 is fine around 400mbps but the 2.4 is slow, not achieving more that 80mbps

This was with a hub4 the engineers tried a hub5 with similar results. Tests were taken with only one device on the 2.4 next to the router.

He said he would get back to me.

Any ideas please?

Thanks

Sounds about right for 2.4Ghz, good even!

Re: 2.4ghz Slow

Really that is weird, why wont it get up to full speed.

I would like to know what others can achieve on 2.4ghz.

I was on TT and regularly got 70ghz on a 80ghz package.

Thanks

Re: 2.4ghz Slow

See this
__________
For example, my Macbook Air and iPhone7 both get 220mbps on my Vivid200 wifi connection (and 220 on ethernet of course). However, on wifi, they only get that when I put them onto the 5GHz network. Sat in the same spot if I then flick them over to the 2.4GHz network, they max out at 50-60mbps (others on here get even lower [<50] on their set ups) - it's just the limitations of the wifi technology!

Re: 2.4ghz Slow

Hi,

It says here it can achieve up to 600mbps

What's the Difference Between 2.4 and 5 GHz WiFi? (socialwifi.com)

Strange .............

Does the HUB support it...no (Supports UPTO 3x3 so 450Mbps).

https://kenstechtips.com/index.php/virgin-gig1-fibre-review

Does your device support it... probably not.

https://www.digitalairwireless.com/articles/blog/the-maths-behind-4-stream-2-4ghz-data-rates-explain...

The router and the device must support four simultaneous streams, which most will NOT support, for UPTO 600Mbps on 2.4Ghz.

Re: 2.4ghz Slow

It all depends if it 1x1 2x2 4x4 mimo, if supported. Most phones iPads are 2x2. Also bandwidth on VM hub is 20 Mbs, you can go to 40 Mbs on other routers, but you just end up with interference. Try these ‘real world’ figures:

Maximum speed comparison

 
2.4 GHz Theoretical Speed Real-World Speed
802.11b
11 Mbps2-3 Mbps
802.11g
54 Mbps 10-29 Mbps
802.11n
300 Mpbs150 Mbps
