Extreme speed loss

This problem has been bugging me for quite some time now.
I have a brand new Airport Extreme, making it the 3rd I've purchased. I've got a very reliable cable modem, and comcast recently verified that everything is fine with my line. So why is it that when I first turn on my airport, I have speeds of 2.4mb, but after about 15 seconds, it drops into the kbs sector?
This speed loss is really starting to upset me, and I've tried my best to fix it. Anyone have a solution?

In addition to Franks always excellent advice see if this link helps as well.

How to minimise speed loss through wireless network?

I have recently had a new fibre-optic broadband installation installed & the network speed (via speedtest.net) is an impressive 3-400Mb/sec download & 100+Mb/sec upload, although these are only achievable with my MacBook Pro connected directly to the supplied router with a gigabit ethernet cable. Connecting with the ethernet cable to the nearby Airport Extreme gives a slight loss, but still gives 300+Mb/sec. However, going wireless results in a huge speed loss down to about 50Mb/sec close by and down to about 20Mb/sec max (often only 5-10 Mb/sec) in my office, in a separate building about 30 feet away in which the network is extended by an Airport Express.
This Airport Express is version A1264 which Wikipedia tells me is b/g/Draft N standard. Will I get any better connection speeds if I upgrade to the A1392 dual-band version?
Don't read this as my being huffy about the slowness of 20+Mb/sec, when most people can't get this - I was on about 2-3 Mb/sec until the recent installation and am more than pleased with the speed but want to get the best from the potential that is there.

Airport Extreme Internet Speed Loss

Hello All,
Just bought a Airport Extreme base station and i have the following issue.
When i connect my iMac directly to the Cable Modem is receive a speed of:
UP: 9.97Mb/s
Down: 118.91Mb/s
Ping: 8ms
But when i connect my Base Station to my Modem and connect the iMac (wired) to the Basestation, i receive:
UP: 8.74Mb/s
Down: 78.90Mb/s
Ping: 9ms
This is nog occasional, this is each time i switch between Modem or Basestation.
Can this have to do something with the settings?
Please help...
Thanks,
Richard

Wow, I'm jealous. I pay $60 monthly for 30mbps. I've heard the US is way behind the rest of the developed world in internet access but I didn't know we were that far behind... Thanks for the reply.

Airport Extreme speed limit to 130 Mbit

Is it normal that the maximum speed of the Airport Extreme is always limited to 130 Mbit when you've configued it as 802.11b/g compatible? I've use the Network Utility to check the Link Speed.
I need the 802.11 g mode because sometimes I need to connect some older PC's.
Also before mine network was a wired when. The link speed was 100Mbit. When I copied a file from a Mac to another Mac I got have some transfer speed about 8 a 9 MB/s. (I use the iStat widget to check this).
At this moment mine network has become a wireless one. The link speed is 130Mbit which is higher then the wired network. Although when I'm copying a file from one Mac to another one mine speed transfer is maximum 4 MB/s.
This is half the speed as before.
Is this behaviour normal? Of-course I didn't expect the same results as with the wired network but at least I expected some better results.

I have also noticed that when you setup the Airport Extreme to only the 'n' network at 5GHz you will get a maximum speed transfer of 270Mbit.
But I've find it very strange that when you select the network for b/g/n that you will always be limited to a maximum transfer of 130Mbit. I find it normal that the speed of the network will slow down at the moment that there is a connection busy with a device that only supports b/g.
Most people do need this compatibility. Game-consoles, smartphones, printers and so on. 90% of the time those devices are not connected with the network.
Whenever you setup this mode of compatibly you will have always a slower network then the Airport Extreme is capable of doing. Of-course you can connect another router when setup for 'n' 5GHz and the other setup for b/g. But this isn't the way to go...

Low AirPort Extreme Speed

I have an Airport Extreme BS [g] connected to a cable modem. My iMac and Mac Pro both have full bars and get just about 10mbps download speeds. My G4 MDD on the other hand is one bar down from the top and gets 2.82mbps down speed, pathetic Why such a dramatic difference when all the machines and equipment are in the same room?
When I connect the MDD via Ethernet directly to the APBS my speed jumps up to just about 10mbps down just like the other machines. So, bad AP card? Other? What can I dig into, to troubleshoot?
Thx for any help,
Tony

Hi.. I also want to know what I can do to tweak my 802.11g pci wireless card's speed as well.. I have the 2003 PM MDD dual 1.25(last to boot into OS 9). My wireless speed sometimes is slow, and sometimes its fast. Should I just get a wireless n usb or PCI card, or is there a way to make my wireless G go faster?
Also, its strange that I can't access the airport software on my computer even though this pci card is a wireless G card?

Maximizing Airport Extreme Speed

Hello All,
I'm currently running my home wireless network with an Airport Extreme with b/g/n 2.4GHz setting. I want to be able to run a/n 5GHz only, to take advantage of the full speed. The issues is my roommate only has a g-enable Dell, and he would be without internet access. Can I get an Airport Express, extended it wirelessly, set it up for him with b/g/n 2.4GHz, and still have full speed with the Airport Extreme? Thanks!

Hi...
You can't do this wirelessly, but why not do it cabled? Connect the express to the extreme via cat5, then configure the extreme as the "master", with wireless options of 802.11n 5ghz only selected, and aldo set as the DHCP server. On the express, set it to 802.11g only, and configured as a bridge. You'll then have 2 wireless networks a g and an n, but they are on the same LAN so DHCP, printer sharing and everything works fine. The only thing is they would need to be close together and connected by a cable. That's how I've set it up, an n network for the appletv and one macbook, whereas the rest of the wireless clients go on the slower g network.

Big speed loss since Frriday's Failure

To be brief my speed dropped off from 6mbps before Friday's outage to 1.5mbps yesterday morning when service was restored and now it's barely managing 640kbps today. After a nice session with BT India to verify we aren't plugged into the toaster etc they say it's just a coincidence that this has happened and it must be something with our line (I totally disagree as nothing changed apart from the outage happening!)
IP profile is set at 1000 - don't know what it was before Friday as wasn't interested. Data below obviously shows that we've only been connected 4 hours but this is at the behest of BT India making us clart about.
Bottom line is that come WednesdayI need to have a connection capable of supporting me watching some online lectures i.e. watching live video and this connection obviously won't support it - is there anything I can do to get BT to pull their fingers out? I'm at the point of ringing around friends and family to find someone with a suitable connection I can spend 2 weeks at but obviously this isn't a cure!
Any advice that doesn't involve waiting for days greatly appreciated.

Update since Sunday's posts:
We told by BT India that someone would call back about problems within 24 hours (i.e. by 1400 Monday). Nobody did of course. When I then called them back I was told there wasn't a fault on the line (strange because there was on Sunday but for some reason I didn't believe it). He then had me swap my filters (again - and I've got 5 of the buggers so they can't all have mysteriously failed since Friday!) and told me that it was being passed to the engineering department who would called within a three hour window today - nobody called.
I know the common consensus is to wait for things to recover by themselves (My IP Profile is at 750kbps whereas we used to get >6meg) however I have just paid a considerable amount of money on a distance learning masters degree that reuires my to take part in (not just watch) lectures via streaming video and obviously I can't do this downloading at 680kbps (I've already tested it - I can't even get BTs own help videos to load).
Is there anyway I can get some intervention and get my IP Profile changed manually? If not I may as well dump the homehub in the bin and use my mobile for email and what little surfing I do.
Sorry for the moaning posts but BTs customer service should be thoroughly ashamed of itself. It's bad enough being patronised and lied to but when you pay or the plaesure it's just doubly insulting. Rant over.

Airport Extreme Speed Tests (2GHz vs 5GHz)

I tested a 702mb file transfer (sending and receiving) with the Apple Extreme 802.11n. One system (20" Intel iMac) is on ethernet and the other (17" MacBook Pro with 802.11n enabled) is using the wireless connection. I wanted to find out if I should be running 802.11n in the 2GHz or 5GHz range. I have always though the better the signal strength the better the connection would be, but my findings were completely opposite.
The laptop remained in a static spot with no microwave oven or any strange electronics around to interrupt. I transferred the file up to my iMac and back down and viewed the network traffic through the Activity Monitor. I also used iStumbler to check my signal strength.
I know my testing has its flaws, but this is what I came up with...any recommendations to get better speed or am I looking at the best case?
Test 1:
2GHz - Channel 6
Signal Strength: 62%
File Send (Average/Max Burst): 2.6MB/s / 5.5MB/s
File Receive (Average/Max Burst): 5.8MB/s / 8.2MB/s
Notes: The speed is all over the place for both sending and receiving. The graph in Activity Monitor looks like a heart monitor.
Test 2:
5GHz - Auto Channel
Signal Strength: 35%
File Send (Average/Max Burst): 8.3MB/s / 8.5MB/s
File Receive (Average/Max Burst): 6MB/s / 6.9MB/s
Notes: The speed was not sporadic like the 2GHz test, although this time the sending was faster than the receiving.
Test 3:
5GHz - Auto Channel - Interference Robustness Enabled
Signal Strength: 36%
File Send (Average/Max Burst): 8.7MB/s / 8.8MB/s
File Receive (Average/Max Burst): 4.1MB/s / 5.8MB/s
Notes: Slower on the receiving than Test 2, but a bit quicker on the send.

Your general results are consistent both with my experience and what the protocol should be able to do.
1. Your absolute best results will be in .11n only mode at 5 GHz. .11n mode is more efficient and it is only at 5 GHz can you use 40 MHz wide channels. There is also essentially no interference at these frequencies particularly in channels 36, 40, 44, and 52 - the defaults for .11n at 5 GHz.
2. If you use .11n at 2 GHz you will have three problems: interference from ovens and other Wi-Fi networks, using .11n in compatibility mode that allows it to share with other networks at these frequencies, and the use of only 20 MHz wide channels.

New Airport Extreme Speeds?

My new Airport Extreme (ac) arrived at much the same time as my ISP provided me with FTTC and a connection speed of up to 70 Mbps.
My VDSL modem (wireless disconnected) is connected by Ethernet (+Power adapters) to my Airport Extreme, which in turn is connected again by Ethernet to my Mac.
I created a wireless network in the Airport configuration in the usual way to service other appliances.
The wireless connection as measured by the speedtest app (latest toy) on my iPod Touch gives me:
Ping 79
Download 10.46 Mbps
Upload 6.41 Mbps
At the same time, Speedtest.net gave me a connection speed from the computer (presumably the Ethernet connection) of
Ping 31
Download 65.89 Mbps
Upload 7.41 Mbps (usually 16+)
The associated Pingtest reported
Ping 33
Jitter 1ms
Line quality A.
Reading through the discussions, I realise I may not be comparing like with like, but I have to admit to being somewhat disappointed by the wireless speeds achieved and possibly their quality from the Airport Extreme.
I would appreciate knowing if it possible that I have made some glaring mistake in my Airport configuration that would account for this?
Thank you in anticipation,

Using power line adapters is going to introduce an element of uncertainty.
Anything resembling a controlled test will require that you first measure the speed with your Mac connected directly to the VDSL modem, followed by comparing that speed to the Mac connected directly to the Extreme.
Remember to reset the modem between those two measurements. Usually that just means powering it down and letting it rest for a moment or two.
Any latency introduced by the Extreme itself should be negligible. Repeated tests may be necessary due to local variations from your ISP. Claims of "up to 70 Mbps" means just that - you may, during ideal conditions, enjoy connection speeds of 70 Mbps. Other times, it can be much less. Perform your tests during times of low demand.
Following those tests, introduce the power line adapters and test again. Household wiring is a poor substitute for Gigabit-capable Category 5e or 6 Ethernet cable.
Then, unplug your Mac's Ethernet connection and measure its wireless connection speed. Any resulting reduction in speed will be a function of your wireless environment and the protocol you are using. At present, the newest MacBook Air models are the only Macs capable of using 802.11ac.
An iOS device's speed will always be less than what a Mac can achieve due to its hardware power constraints.

Memory Speed loss with CPU upgrade 2.6 - 3.0

I have a n 875P Neo board with 2 banks 512m DDR400
I have just upgraded my cpu from 2.6G (800 FSB) to 3.0G (800FSB)
My BIOS is ver 1.8 (8/9/ 2003)
I have found that my memory speed timings have dropped by 30% since the upgrade. Will I get better results if I update my bios to ver 2.0 (the latest bios)??
Sysoft Sandra Memory Benchmark shows to memory timings to be about 25% lower than expected
Can anyone help??
Thanks
M Miller

The 875P Neo and 865PE Neo2 boards are kissing cousins They have a lot in common.
It would help if you create a signature and put all your hardware information in it. Things like what type of video card and what type of ram all have an impact on what performance modes you can operate under. See the Rules at the top for what to include and how to do it.
You should also read P4 Neo Unofficial Guide and Moan Guide.

Re: Serious speed loss on infinity all of a sudden

A couple of times a week my upload and download speed via Wi-Fi drop to a snails pace. Normally I get 30Mbps download and 7Mbps upload. Often on a Monday morning I get 0.1Mbps both up and down on all wireless devices, the connection is reliable but unusably slow. I can solve this by connecting a laptop via Ethernet to the Wireless router or by rebooting the router. I logged a call with BT on this but of course when you run their wired test it responds OK so they are not interested. I have run Wi-Fi analysers on the area and switched wireless channels to and solve but the problem just seems to come back every few days. A faulty router maybe but why does it work OK 90% of the time and then stop out the blue. Any ideas appreciated !!

A WiFi analyser cannot detect other devices that use the 2.4GHz band, like video senders, which can blot out many wifi channels.
You should be able to find one channel out of 12, which works best. Do not rely on Smart Wireless, as it can only choose three channels

Serious speed loss on infinity all of a sudden

Hi,
Any advice welcome - My infinity download speed has dropped from 40mb to just over 6mb since yesterday. Upload speed has remained at 10mb - I havent made any changes to my equipment. Are there any reported issues - nothing I can find on the website about system errors.
I have made a call to the helpdesk but after following all the generic tests I am being told theres no errror - shall I post the results of the bt speedtester so someone can have a look?
Hopefully someone here can help!
Many thanks,
GerryP

Download speedachieved during the test was - 8.66 Mbps
For your connection, the acceptable range of speedsis 16 Mbps-42.2 Mbps .
Additional Information:
IP Profile for your line is - 42.2 Mbps
Upload speed achieved during the test was - 8.85Mbps
Additional Information:
Upstream Rate IP profile on your line is - 20 Mbps

Update to Airport Extreme - speed increase?

Seems like I experienced a speed bump when I did the upgrade. Anyone else think that, or is it just a coincidence?
I tested with www.speakeasy.com .. came in at between 13000 and 14000 kbps.

Unless you are running a FIOS (fiber) Internet connection you shouldn't notice anything different. Although, the speeds you listed would exceed an 802.11"b" connection they are far from exceeding an 802.11"g" connection.
What we need to know is what speed ranges were you getting before the update and what speed does your ("g" max speed) iMac G5 get?

Recently upgraded my service with Time Warner Cable to Extreme speed and got a new Motorola Surfboard SBG6580, now I get Error -50 constantly. Anyone else have this issue?

I just upgraded my service to Extreme with Time Warner Cable and got the motorola surfboard sbg6580 modem. Now when I try to dowload any videos or TV shows on iTunes, I get an Error -50 mid download. Anyone have a solution for this? I am using a PC, not a Mac computer.

I don't want a used replacement phone when I just bought mine. I have had your "like new" replacements before for my basic phone and had a ton of issues straight out of the box, which is why I don't want one when my phone is so new and I have had issues since day 1! Not once on my several calls to tech support, did anyone tell me to go exchange it the first 2 weeks. That is just one reason they want to send me a replacement. Another is the USB does not work properly, I can't use it to do anything but charge the phone- and my husband has the same phone so I know is not the cord or the computer because his works perfectly. The connection was sporadic so I just installed a new SIM card. So far that has helped with dropping 4g all the time. I have never been able to back up my contacts, spent 2 hours on the phone with tech support the first night I got it just trying to sync the contacts from my old phone. It never worked, I had to hand input the numbers. If Verizon won't do right by be and give me a new phone, I at least would like them to get mine working like it should have when I bought it.

BT Infinity Speed loss

HI to all
I have been very happy with my infinity up until two weeks ago! i noticed that my speed has dropped down from an avererage of 36-38 MBs to 13-14 mbs
i called BT on friday last week and was told that, due to BT trying to upgrade the speed of infiinity off of my exchange, it had caused a fault there by decreasing the speed of it, the advisor said it will take about 5 days to fix and not to call back untill atleast sat 18/06, as calling back before will wipe out the call log created by calling him??
does this sound right or have i been fed one,
I live in Chippenham wilts,

if that is the repair status shown on the website then that should be all the information that anyone else will have just a matter of waiting for the 18th
