100M : Virgin Media WNDA3200 wireless adapter

[truthspeaker]

Netgear WNDA3200 only connects at 48Mb. how can i make it to 300Mb?
the wireless range is excellent. full 5 bars

WINDOWS 8.1 Pro
Superhub 2 setting:-
Wireless Frequency 2.4GHz I tick Up to 300Mbps (best for wireless performance)
untick OBSS

if Netgear WNDA3200 connects at 48Mb then i can't get 100Mb download speed i only get 20Mb download speed. can anyone help me?

Have you read the manual??
Some TS tips in there ftp://downloads.netgear.com/pub/netg...UM_25Jan11.pdf

virgin media Netgear WNDA3200 manual not helping.

i restart the superhub 2 then its goes back to 300Mbps
then after few days goes back to 54Mbps? and stays like that.

and i get 18Mb or 20Mb download speed when it should be 100Mb download speed.
if the wireless adapter stay on 300Mbps then download speed can reach 105Mb. but if its on 54Mb only 20Mb download.

i check my WiFi status
Connection:-
IPv4 Connectivity:- Internet
IPv6 Connectivity:- No network access

SSID:- WM virgin media hub
Duration:-
Speed:- 54Mbps
Signal Quality:- 5 full bars

you could tell the pc to forget the 2g and only use the 5g ssid. if it moves to 2g, and you have a wireless g device connecting to 2g at the same time the speed drops to 54

[truthspeaker]

Wireless Frequency 5GHz
Up to 450Mbps (best for wireless performance)

5GHz Signal Quality is 4 bars

WNDA3200 connects to 5GHz at 300Mbps download speed is 80Mb download, but web pages are running to slow and sometimes looks like it freezes on 5GHz.
on 2.4GHz web pages run faster.

how to i get 2.4GHz to connect at 300Mbps ?

[General Maximus]

by setting the router to N only for 2.4ghz. As JB said, if multiple devices share the 2.4ghz band and you have an older device or phone which connects at G, then the router has to run all the devices on that band at that speed, even if they were previously connect at N/150/300/whatever

[truthspeaker]

thats funny because i have a 2nd computer using TP-LINK TL-WDN3200 N600 Wireless adapter and it connects at 300Mbps to 2.4GHz

and the 1st computer with Netgear WNDA3200 only connects at 48Mbps or 54Mbps.
so can't be all the same.

both computer running at the same time with different speed. can anyone explain that please

[General Maximus]

the technology doesn't work that like. On 2.4ghz all devices run at the speed of the slowest device.

Wrong

Wrong.

300Mbps doesn't normally work for long on 2.4Ghz because the Superhub has received a firmware update from VM that (shock horror) actually makes it obey WiFi guidelines (which state 300Mbps should automatically shut off when it detects other networks in range)

thanks for providing the link to a search result from Cisco which pretty much backs up what I said:

"Wireless N is supposed to be interoperable with Wireless A, B, and G, but it doesn't always work that way. Some older clients might not be able to connect at all, even when the wireless router or APs are in mixed wireless mode. Then when the older clients can connect, they'll slow down the network.

Some clients may take a heavy 80 percent cut in their throughput. To prevent this problem, consider forcing the new APs to use only Wireless N, and keep the old router or APs around to support the old clients.

Although connections among users on the Wireless N router or APs with Wireless G users will still be bottlenecked by the old clients, the throughput cuts on a mixed mode Wireless N router or AP can be much worse"


Although to balance the argument I have just found this as well:

"Unlike in the 802.11B backward compatibility mode, G devices do not impose any performance-degrading behavior on N devices in order for them to be backward compatible. 802.11g devices are able to recognize the 802.11n preamble, and they play nicely in terms of knowing when one or the other is trying to transmit. The preamble tells which modulation scheme will be used, so the N devices can speak N, while G devices can speak G. They don't have to resort to "Esperanto" as with B in order to cooperate.

This means that when the G device is associated but not active, it has no impact at all. When the G devices are active they will consume air time roughly in proportion to the amount of data being transferred. This air time would of course be at the G rate as opposed to the N rate, so in the event that the airwaves are fully saturated (eg by a local file transfer), there would be some reduction in the total Mbps achievable by all devices collectively, but there is no penalty for having the G devices associated"

Funny how you picked the 5th result down on that page, one from Cisco Press quoting a third-party article, not by Cisco or any of their own employees. It's a rather non-technical article that doesn't contain any hard information.

Nonetheless notice at no point do they say they will slow down all devices or cause any device other than that which is G only to operate at G speeds. There is undeniably a performance impact but it remains completely untrue that having an older device will force all devices to run at the older device's speeds. This is just a excessively repeated urban myth.

Perhaps you should read one of the other results, slightly more relevant:

Performance Impact of an 802.11n Capable Access Point in a Mixed Environment

Which describes exactly how and why backwards compatibility impacts performance. But notice again that at no point do they say all devices will be stuck at G speeds or that the whole network operates at the speed of the slowest device.

[truthspeaker]

exactly. G device can't make N device run slower.
must be something wrong with the Netgear WNDA3200 adapter or maybe the drivers don't support windows 8.1

[qasdfdsaq]

Unlikely to be the latter, you have a Windows Hardware Quality Labs certified driver installed.

As if that's ever ensured that a driver was stable, secure and not liable to brick the whole system.

[qasdfdsaq]

No but it ensures you can't install drivers that are not compatible with your operating system.
