2.4GHz Wireless N Issue

[goumet]

All I have a TP-Link Ultimate router, which for my first dabble in Wireless N is proving a real pain.

I can connect to it at 300Mbps for about 5 minutes, and after that - 130Mbps.

I've tried changing channels and no difference, and I understand from reading up, its due the router detecting other 2.4Ghz Wireless G routers in the area.

Does this sound likely? and is there any fix - apart from by a 5Ghz Router?

Are you actully steaming anything that needs 300mbps? its probly just low signal

Tried changing channels? Changing channels on my router managed to get me another 15% :)

id go for this works most of the time for me

Lmao he says he has in the first post :knock:

Tried every channel option I have , plus the auto channel mode and no joy :-(

Sorry, didn't notice. How are you measuring your bandwidth?

[goumet]

I'm going by the windows connection status.

Also, copying files across my home server, connected at GB, when its at 300mbps I get about 11MB/s when it drops to 130mbps I get about 8.

Very frustrating, I have no problem working at 130mbps, as long as I get the range, but if I buy a 300mbps route, I at least expect it to connect at 300mbps, even if I don't get the throughput.

I have seen reports of issues with different makers of stuff getting confused in this band.

I gave up on it.

My connection suddenly became solid, although it may have been due to other tweaks at my end.

This might be one of those things where you hit a brick wall when Netgear tries to talk to TP-Link, for example.

[goumet]

connection is solid enough, so I guess we'll have to see how it goes.

thanks for the replies.

Are you getting solid signal strength AND quality?? sometimes you can get 100% strength but only 40-50% on quality due to interference from another source.

TP Link have detachable antenna, so buy some +9db jobs.

Is your PC using a card or a dongle, as they are often the weak point, not the router; and as mentioned above, different brands can sometimes refuse to play with each other; the worst being Netgear - TPLink; where, positioned next to each other, they will only connect at 1mbps!!!!

[goumet]

Thats what I'm getting in about 10 metres from the router. Its an Intel Card in my Laptop.

[GentleGiant]

Do speeds improve when they are closer together?? If so it is a signal issue; if not, then the Intel and TPL dont like each other :cry

[goumet]

No change - even if I'm sat next to it.

I thought it might be the card - just wanna be 100% sure before I buy another one.

Any advice - Internal preferably.

try messing with the wireless device adapter setting in the device manager
enable jumbo packets

Tried \ checked and double checked all Wireless settings.

Jumbo Packets are only any use when moving large files around networks, they can \ do slow up smaller files.

One last thing I can think of trying before spending money.

Switch off all un-needed services and background tasks, optimise the HDD and try it again.

I am wondering if the slowdown is due to the lappy running out of steam, or being unable to write the data to the HDD fast enough.

Ideally, I'd like to find someone with another wireless n laptop - or may borrow one from work.


Thanks for your help folks - I now see why wireless n has never really been adopted as a standard.

Don't tell that to the multi-million dollar wifi industry.

Or the PC makers, or the phone makers, who add it as standard to their systems.

It is a widely adopted standard. Probably IEEE.

Unfortunately, it falls apart in the hands of amateurs like me. I went through wireless hell until I turned off conflicting transmitters.

[goumet]

Maybe you just get what you pay for, if it got a nice expensive 5ghz router I wouldn't have these problems.

It's maybe a standard, but I've never been to an enterprise yet thats deployed an 'n' network

[GentleGiant]

I think a lot of the problem is that "N" was in "draft" for so long. All the manfs starting adding their own "bits" to their "draft N" products and we ended up with problems getting different makes to talk to each other. I had shed-loads of trouble with a Netgear Router and various "N" spec cards, but it worked flawlessly with every "G" card I threw at it (well, until it melted, carppy thing was always overheating)

[michaelkenward]

This is an interesting discussion of the N standard, with some useful insights.

If it worked flawlessy, would the average home punter gain much?

I gave up with it when my network was hanging all the time. After abandoning it, no problems. But I also simplified my network at the same time.

Is it worth trying to reimplement N standard with my simpler network?

[goumet]

I think the "standard" really needed clarification and testing before the products went to Market.

If I rang the manufacturer and tried to get support for an issue and got the reply "sorry, sounds like interference or conflicts with other networks" I could be the kind of customer that would return the products with negative comments giving the whole "n" thing a bad name - which googling it already has.

If I'd spent big money on this kit, I'd be returning it - but I can live with 130mbps and the gigabit switch is what I actually wanted - the wireless was a bonus.

[GentleGiant]

I agree, but the messed around for so long that the manfs wouldnt wait any longer and started selling it with the standard incomplete
