This will be my last answer to you, as long as you are not contribute useful technical questions or useful technical answers along the issue discussed here. because I will not longer feed the troll's.

I suggest you to read in order of appearance:

Read and learn as much as possible about networking and WLAN.

Than eventually come back and make usefull conritbutions here instead of rant and trolling the forum.

Guys specially lupunus instead of trying to educate people on what is MB vs Mbit and showing people networking books, we are dealing with a wireless issue on a specific model of spefic line of MacBooks Pro, this is NOT a NETWORKING issue. The issue what Im demostration happenes on new equipment while doing somethign specific. This is not a networking issue!!!

Otherwise find another party to crash, this one is for meaningful conversation only.

mfwells,

I'm contributing along these forums for just a couple of weeks, but I use the Community for years now to find answers, hints and help if I stuck on a problem with a Mac.

I've learned along that timeline, that "Csound1" exactly knows what he writes and also have a lot of knowledge and experience about Mac's, networks, wireless and the technical hustle that can occur with either of them.

I suggest to lent him a ear (as we are on a written form better an eye 🙂) and read his advice carefully.

Peace - Lupunus

Please once again, can some one on this forum confirm they dont have the issue I described with large file transfer over N network and pings do not drop and able to open webpages stream etc ?

The demonstration is useless as it occur in every wireless network under the given parameters, as long as at least QOS (Quality of Service) is enabled to priories user data. Disregarding other reasons why the reported behavior may occur e.g. the traffic has reached the maximum capacity of the line.

"I just bought a brand new AirPort Extreme thel atest and greatest one. Connected it from the box setup 2.4 and 5 network connected my NAS and my MBP to it transferred a 300MB file, while speed of transfer is amazing peak 22mbps. Here is a ping at the same time."

And what steps have you taken to verify that it is not the NAS, particularly after any updates to your computer's OS may have occurred. What security set up are you using with this new AE? Have you verified that it is the ideal method for both the computer and the NAS. Have you verified that there is nothing that could be a source of interference in your own possession or at a neighbors

These are questions you would probably be asking your clients but you fail to mention the answers and the solution could lie in those details.

Okay, I have exactly the same Problem (lost Packets under heavy load) when Pinging sth.

So how could it be that I have this Problem only with my MBP 2011 running Lion, but not with my MacBook air also with Lion and not with my Netbook running Ubuntu Linux. The Problem also does not exist when I install Ubuntu on the MBP 2011. So it has nothing to do with the hardware, but def. with sth. of the software. Also I have this issue with three differnt Routers, always the same, MBP 2011 has dropping Packets and from time to time heavy problems when I try to load a page. In contrast when running Linux, on this Machine or when I use my MacBook air, or Netbook with Ubuntu no Problems at all!

I do not get the point why this is ignored, and peopla try to tell others that this is normal!!

Go to a Apple store, transfer a big file and Ping, you will have packet loss with every 2011 MBP, but not with the MacBook airs! So please explain this!

That's a point to set the lever on.

This issue was attributed to the fact that with the release of 10.7, Apple discontinued support for DHX authentication and implemented, in its place, DHX2 authentication. DHX is an Apple authentication protocol. The change from DHX to DHX2 is the result of upgrading Netatalk.

For that a lot of NAS-Systems produce trouble now, as some NAS developers had fail to update their firmware.

I have plenty of wireless knowledge thanks

You stated:

1. There's absolutely nothing wrong with the infrastructure, antenna placement, etc....etc.....of the WAP and the laptop.

2. There is also nothing wrong with the interference(s)...only possible sources are 802.11g and n networks located 50-100 + ft. away, on different channel(s), etc....etc... and very low signal levels.

So I'll take you at your word that your wireless is working correctly (even without testing) and leave you to fix it with help from others.

I don't

@ Csound1

On a early 2011 MacBook Pro ?

@everyone else.

There is no issue with NAS, this happenes under SL and Lion on this MacBook and the one I exchange it for. This did not happen on 2 MBP before that (earlier models not 2011), this happens conencting to SMB share, FTP, AFP, on this NAS on APBE connected drive on anything else connected to my network thats able to sustain this speeds to the MacBook Pro and only to this Early Model MacBook Pro.

I tried this same test in Apple Stores in NY Metro Area and all of them have the same issue. Even hitting 22MB/s which is around 176megabits should not show that much drop and actually on any other device this does not show this much drop approching this same speeds.

Please dont make me look stupid or disregard me not knowing what I`m talking about, since February I made many many diffrent test and many diffrent locations. All Early 2011 Macbook Pros have this issue. I havent seen one that doesnt. If yours doesnt please prove it, send a screen shot with 3 things in it (and not a photoshoped one) with Activity monitor showing current speed, the transfer bar, and an open Terminal with a ping to something local.

Just to add I can put an early 2011 MBP next to earlier model and do the same test, the other MBP will not drop 1 ping!

On all my machines, which range from 2008 to 2011 Mac Mini's and 2009 to 2011 13" MBP's, they all connect correctly (routers are always Apple Extremes, varying vintages of them too)

@Csound1

I`m not asking you about the other machines.

Please once again on a Early 2011 MBP open terminal with a ping to something local like your gateway while transfering a large file approching high speeds. Do packets start to drop ? Let the transfer finish. Try it dont just say they dont try it and see...... and if you can take a screenshot of that so I have proof for me and apple store.

If you show me that they dont. I`ll be in my local apple store tommorow eather replacing this macbook from February or asking them to switch logic board, WIFI cards etc...

I said all my machines, there are 3 2011 13" MBP's in use, they stream for 14 hours per day and they don't have any issues. OK?

WoW are you even reading what I`m saying ? Can you please try what I`m saying ?

Streaming doesnt prove anything as your troughput might not be high enough. Actually its a good test, when you do stream and trasfer a large file what happens ?
