Airport Security, Speed and WDS Problems

I've been reading the posts here about the new AirPort "n". I also posted my own thread about the curious speed issues I've observed. BTW, my computers are all "" capable. An off-the-cuff summary (please correct me if I'm wrong):
1. WDS in any practical form is hit or miss. Creating extended networks appears to be a basic non-starter, though AirTunes seems to work in many cases. Manual vs Assistant setup sometimes helps, but as an experienced user, I find this all a bit vexing.
2. Enabling any kind of security has a predictable and detrimental impact on speed. Personally, I've seen WEP security grind formerly 5.7MB download speeds to less than 500, WPA routinely takes 5.5MB to less than 2MB, and turning off security but implementing Timed Access slows my network to less than 80kb download speed.
3. Turning off security entirely seems in my case to allow the AirPort to function more or less properly. Of course, no security is unacceptable.
4. There is a resignation to the idea that a future firmware update will fix what are fundamental problems with a perhaps too-early-released product.
I've been pretty methodical about my observations and tweaks -- resetting the unit to factory, sing the interface setup automation as needed, re-powering between changes. I've read about others ganging multiple AirPorts with success. While the new AirPort is not quite a doorstop, it appears to be not-ready-for-prime-time. Or maybe mine is just a lemon.
In my case, I've rectivated my previous-generation Extreme complete with security, AirTunes, network extension, etc (even used the new Utility to do all the setup). My speeds are happily back at 5.7MB down.
Thoughts?

I appreciate the response. I'd usually agree that "operator error" is at the root. After over 20 years of using Apple products, this is the first that has me scratching my head. But I'm not new to this -- I built one of the first and largest Xsan installs in the U.S. I'm an early adopter, and most always an early success story.
As I said earlier, I've worked the scenarios very methodically. It could very well be that this is a hardware issue with this particular unit, or a higher percentage of units is failing than the norm. That would not be new - early new hardware in some Apple product line have experienced teething problems. Not a long term worry, though.
My next step is replacing the hardware, carefully observing serial numbers, etc.
The question, btw, is implicit -- is there something altogether simple that escapes me and a number of reasonable users that is causing a problem?

Slow macbook pro since the airport security patch and last OS update about a week ago..

Hi, my Macbook Pro has slowed down to a crawl on the internet since the airport security patch and OS update about 1 week ago. I am using Firefox 3.6.17 and have tried all versions up to date (but 3.6.17 is the best). Same issues with Safari too. I am using an Airport wireless modem also so should not be any issues with compliance. Local programs seem to run OK... but the internet is slow enough to grow a beard... Do they have a patch for this issue. It only started after the updates. Was blazing fast until that.

Touchpad Speed and Finder problem

Alright, I'm using a Penyrn baseline Macbook Pro that I picked up when it first came out. I'm loving it. It's great. So far, I've had a few big problems with it though.
1) When I've been playing some graphic intensive games, like World of Warcraft, my Finder and dockbar freezes. Like, nothing would work, I couldn't alt-tab and while my game would work, I'd have to reset the entire computer.
2) Again, while playing World of Warcraft, sometimes my Touchpad speed would get reset down to a slower setting. When I try and change it, it won't stay and often whenever I alt-tab between programs, it'll go back to the slower setting.
3) Is there any place, Apple Store and what not that I could get it in for a check up? There's a few smaller things I feel IN the keyboard that's a bit defective and pixel problems.
thanks!

Airport (802.11n) and WDS

Hi,
Does someone can tell me what "speed" will I get with two Airport 802.11N with WDS setup ?
I alreday know that a WDS with an Airport 802.11N and an Airport Express or Extreme won't get better than the slowless one : 802.11g.
Thanks
HDR

You'll get 54mbit between the two airport extremes...
Technically yes but the bandwidth available to any client is really only 27 Mbps since all data must make 2 hops and no other data can be transmitted during either hop. Other data can not be transmitted because both base stations are using the same channel.
So if the client requested 54 Mb, it would take one second to go from AEBS_1 to AEBS_2 and then another second to go from AEBS_2 to client. Therefore the total bandwidth is:
(54 Mb)/(2 sec) = 27 Mbps
Don't know where you got 104 Mbps but if the clients were able to use that speed to connect to AEBS_2, the data would take .519 seconds on the second hop. The overall bandwidth would then be:
(54 Mb)/(1.519 sec) = 35.5 Mbps
Regardless of how you slice it, WDS makes a drastic cut on your available bandwidth.

Airport security cameras and videotapes

Hi Fellow FCE Users,
I will soon be travelling through the US to France and shooting some HDV footage with my camera.
Are the completed HDV tapes safe to take through airport security, where they xray all of the carry-on baggage?
Or do the x-ray machines damage the images on the tapes?
Any advice would be much appreciated.

Travel to/from France (or any EU country) should not be a problem. Make sure to keep all the tapes in carry-on luggage, not in any checked bags.
US security regulations allow you to request hand inspection of films & tapes - that will reduce the total scan count by at least 1 scan per round trip. In the EU you can contact airport security ahead of time and request manual inspection (no guarantees they will agree however, but it doesn't hurt to ask).
I have carried various magnetic tapes and photographic films into/out of EU countries and have never had a problem with damage. I always courteously request hand inspection rather than putting the tapes/films through the scanner. In the US, TSA should always comply with your request. In the EU it depends on the particular officers on duty and any local concerns that may prevail at the time you are traveling.
For extra assurance, you can do one or more of the following:
Get an x-ray bag. This will at least provide decent protection from x-ray damage and modest protection from magnetic damage. You could in addition completely wrap the tapes in aluminum foil inside the bag.
Dupe the tapes while you are on your trip. Send one set back via courier (DHL, etc)
Capture the video to disk before returning; preferably to a disk in a good tight metal cabinet (like a G-drive mini). The metal enclosure provides decent protection from EMI and magnetic fields. You could also put the disk in an x-ray bag and/or aluminum foil.

Broadband Speed and Connection Problem

Since the 03/03/11 I have has problems with the speed and stability of my broadband connection.
The IP profile of my connection has now become significantly smaller than my downstream, suggesting that my line had become unstable.
I have checked the internal wiring, the micro-filters and the router, and changing any combination of these does not re-stabilise the line nor offers any speed improvements.
The downstream listed below has gone down over the last couple of days, once again suggesting a line fault somewhere.
I have contacted BT support about this issue via email.
If anyone else has any ideas of what I could try to help sort this out, I would be very thankful
Hopefully I have provided enough information below to allow any sort of diagnosis to be made, but I'm placing my bets on a line fault caused by the bad weather lately.

Hi
results from the BTlineTest
Download speedachieved during the test was - 109 Kbps
For your connection, the acceptable range of speeds is 50-250 Kbps.
Additional Information:
Your DSL Connection Rate :3584 Kbps(DOWN-STREAM), 448 Kbps(UP-STREAM)
IP Profile for your line is - 135 Kbps
No idea why it says "135 kbps" as im obviously getting nothing near that.
One example is "counter-strike" online multiplayer game, when i load it, my Latency is at a normal 40-50.. then it shoots up to 5-600, making it unplayable.
Maybe its the exchange i dunno, might just sort it-self out in the next couple days, but its been 3 days now so im a bit concerned.

MSI NX7600GT-T2D256EZ speed and temp problems?

Hi, I'd like to buy a MSI NX7600GT-T2D256EZ but after reading this comparison in Madshrimps i'm confused:
http://www.madshrimps.be/?action=getarticle&number=12&artpage=1958&articID=460
At the time of this comparison, there was a problem with speed and temperature as you can read in the article. I'd like to know if this problem has been already solved, because i didn't found any new info following this article.
Could someone help me? I really like this card since there is no fan, but wouldn't like to find problems.
Thanks a lot.

Well the Link works but the described issue would only happen if gpu is overheating (as Aaron said). This is automatic core slow down and happens with any GeForce FX/6/7/8 vga when reaching the critical temp. Of course a passive cooled vga reaches higher temps than a vga of the same kind with active cooling. So good airflow inside the case is crucial to keep the temps down. With just an ordinary airflow (two casefans) the 7600GT-EZ never reaches critical temp.
The article you linked to also describes that the NX7600GT-T2D256EZ wrongly reports too high temps. This issue is unknown, I build a system with this vga sometime ago and it never reported wrong temps.

Cisco 837 speed and duplex problem

I have one Cisco 837 connected to Cisco 1900 and Cisco 2924XL. When i set the speed and duplex to 10 full duplex or 100 full duplex i 837 the fastethernet interface is going down. Its working if i set speed and duplex to auto i 837 router. I have 12.4(4)T release on my Cisco 837.

Hi
AFAIK 1900 doesnt support auto negotiation so better manually hardcode the speed and duplex to 10/half or 10/full on the port which is connecting to 1900 and
100/full to the port which is connecting to 2924 coz it does support 100/full.

Two questions concerning Airport Express (speed and disconnecting)

Hello, thanks for any reply.
1) I currently have an Airport Express hooked up to a modem. My experience with it is somewhat lackluster however. The speed can fluctuate sometimes, going from decently fast (although I don't think very fast at all) to qute slow. Also, I more often than not have to reboot the Airport Express (by unplugging and replugging in).
What happens is the green light is on, but my wireless signal (top right of MacBook Pro screen) is empty. I click on it and try to find my signal, which is listed. I then click on that, but nothing happens, and it tells me I cannot connect to it. I then have to unplug and then plug in the Airport Express and wait for it to reboot, which solves the problems but is rather annoying. Any help on how to stop this would be great.
2) I am caught inbetween whether I need to upgrade the Airport Express anyway, into a router with a wired ethernet port. I am utilizing the USB printer and obviously the only port to connect to the modem, but the only way I can hook into my system that does not have wireless capabilities (Xbox 360), I need to unplug the wire from my Airport Express, plug it into my console, and then restart the router, and then do the same thing except with the Airport Express to obtain connection (both are unfortunately mutually exclusive).
The reason I mention that is because I am considering different speed options too. I apologize for my lack of savvy on the subject, but quite simply: Does the Airport Express create the fastest wireless connection out there? Does the Airport Extreme (with wired ports) create a faster connection? When it comes to the Airport Extreme, does that card (I see it in the store section, but I still don't understand it) make the connection much better? Does that card help for an Airport Express?
Thank you so much for answering my questions, I really appreciate it.

Can you further explain the notion of interference, does that mean other wireless signals? I have many that my computer detects, so would this slow down my connection?
Yes any wireless signals at 2.4 GHz will cause interference for the AX. This can be from wireless networks or other devices.
Also, in terms of the 802.11n clients, I know that my computer supports it (From Utilities > Network Utility), but does that mean that the Airport Extreme card is not a factor?
That means that your Mac can connect to 802.11n networks.
Can you please detail what that card functions as.
?? Don't know what you mean by that.
...do you think that the Airport Extreme is then totally worth it, just to clarify.
If you have 802.11n devices and do large transfers between them, then the 802.11b/g/n AEBS could be useful.
If you want to use the AEBS as a file server, then the 802.11b/g/n AEBS would be worth it.

Airport Extreme n + Express + WDS = Problems

I'm stumped and looking for some help. I have an Extreme Base station located in our home office / refinished basement downstairs and an express upstairs in our kitchen. Right now we have 2 laptops running off of the network, 1 mac and 1 pc. Many times when I am upstairs and I open up my powerbook it doesn't get an internet connection. The express is green and the base station is green. I then need to walk my laptop dowstairs to get a signal and then walk back upstairs to use the internet.
All software updates are in place and when I go to my airport utility I rarely see both devices at the same time. Upstairs shows the express and downstairs shows the extreme. The distance between the 2 devices is about 60 feet by walking... otherwise they're actually above one another... about 15-20 feet away. A few questions:
1. Shouldn't I always see both?
2. Many posts talk of security issues - should I adjust mine one way or another?
3. Do I need another Extreme in the mix as a relay?
I've been a mac user for 15 years and this one has certainly got me. Maybe a reinstall with Leopard will answer all of my questions??? Any help would be greatly appreciated. Thanks!

Two words popped out when I read your post: basement & kitchen. Both of these are high potentials areas for Wi-Fi interference.
Before considering adding additional base stations to your WDS, I suggest you perform a simple site survey, using utilities like the following to determine potential areas of interference, and then, try to either eliminate or significantly reduce them where possible:

o iStumbler

Item level security, workflow and tab problems

was wondering if someone could help us out with some problems we are having. We need to up and running over the next two days so anyone who could get back to us pretty quickly would be greatly appreciated.
We are actually having a couple of issues which all revolve around three
groups we have created (for simplicity we have only attached one user to each group). Here are the steps we took:
Problems adding content:
a) Added the three groups to the page group and gave them view access.
b) Turned on approvals and set group3 as the approver.
c) Added the three groups to the page and gave them view access.
d) In the page properties, I enabled item level security.
e) Added an item content area to the page.
f) Added three pieces of simple content
g) For content item1 I granted granted full access to group1(Own, manage, view), for content item 2 I granted full access to group2, etc.
h) WHen I log on as a user in group1 I only see content item1. HOwever, when I edit the page I find I cannot add any items as user1.
i) I went back to the page properties and changed the access of all three groups to "manage items with approval" but let the item level security as it was.
j) When I logged on as user1 I found I could see all items now when I should only have seen content item1. What the hell? Can anyone tell me what I did wrong?
Problems with item level security on tabs:
a) Repeat steps a) through d) above.
b) Create a content region and add three tabs: Home, Work, Life.
c) On the Work tab changed portlet region to item region.
d) Added three items with security exactly as I did above.
e) When I signed on as user1 I saw all three items when I only should have seen item1. What the hell?
f) I monkeyed around with the secutiry at the tab level but it didn't seem to make much difference. ANyone have any ideas what is going on here?
Thanks in advance.

Does the library have versions enabled? Also are these logins occuring within word/excel etc?
If there's multiple login prompts which occur even if entering valid credentials what does hitting escape (after the first prompt) achieve, does the document open anyway?
There's a situation where Office will prompt for credentials if you open a document when you've only got read access but there's a version history (to which you don't have access). This is to allow you to enter more highly privelidged credentials if you
want to.

Slow data speeds and AirTunes problems???

This is a bit weird.
Lately I've noticed that my wi-fi speeds feel very slow. Downloading files, software updates, etc., are very slow. When I plug in via an ethernet cable, everything is nice and fast.
But here is what is also happening - I have numerous Airport Expresses around my house that are only used for music (some have wireless turned off and are connected via a cable and some have wifi turned on, but only for receiving music - none act as a wifi access point). I only have one wifi access point, and that is my Airport Extreme. All of a sudden, I can't stream music, via iTunes, from a computer connected via wifi to a computer on the wired network. But, if the computer is on wifi and the Airport Express is also on wifi, streaming works fine. Vice-versa also doesn't work (i.e. if the computer is on the wired network it cannot stream iTunes to a wifi Airport Express but it can stream to wired Expresses).
Something is very weird, and I think it has to do with the Airport Express not functioning properly. But, I have all the latest firmware updates on it and I'm getting a green light in the utility.
Weird - I know.
Any ideas???

It is very possible that you may have some form of Wi-Fi interference that has been introduced recently in the immediate area that is preventing your AirPorts from providing a good clean signal.
I suggest you perform a simple site survey, using utilities like MacStumbler or iStumbler to determine potential areas of interference, and then, try to either eliminate or significantly reduce them where possible.

VIA KM4M-V motherboard CPU speed and AGP problem

Hello. Please be patient I am not technical I would say I'm intermediate, so please if anyone is kind enough to help, please don't blind me with jargon! I have 2 problems I believe are motherboard related, I shall go thru them both. Any solutions/suggestions will be very gratefully received! Operating system is Win XP Pro SP 2 running 512 MB RAM (64 used at moment for onboard graphics)
I purchased this mother board: VIA KM4M-V. I also purchased an AMD Sempron PR2600+ which should be showing a speed of 1833 Mhz, but is coming up as 1466 MHz. Does anybody have any info please? I have downloaded and installed all the latest deivers and BIOS for the motherboard, and the MSI live monitor says there are no new updates now. Is there something in BIOS I need to change? Or is this a mistake on the manufactuers part? If so, which one? LOL
2nd problem: The onboards graphics weren't good enough for some games I had - it required an AGP card. So I have purchased an ATI Radeon 9550 256 MB AGP card. OK I installed this card. All OK starting up. installed drivers, restarted computer. Was OK then changed to 32 bit colour and change the resolution of screen. When I clicked apply went into energy saving mode. Rebooted. As soon as it went to boot into windows, the monitor went into energy saving mode. Once it didn't straight away and windows started then the screen went distorted then it went into energy saving mode. I went into safe mode uninstalled the graphics hardware booted into windows again and reinstalled looked OK then I rebooted and it did it again grrrrrrrrr I went and disabled onboard graphics (ATI said might be issue on their site) still won't boot. Something I am doing wrong? Is it the motherboard?
I'm thinking that it is both botherboard ::koff:: I mean motherboard It's OK I mean it's better than what I had, but I know it's not what it should be! I am grateful to you guys for your help. Thanks very much
Rachie

Quote from: psywhizz on 16-February-05, 10:01:00
More on this! I am running win xp pro sp 2 BTW. I have been swapping between the onboard graphics and the ATI radeon 9550 AGP card I just got. I have been disabling onboard graphics, then installing from scratch (all virus and programs off). As to power supply/amperes? I have no idea all I know is it's a 450 watt rating and has ummmm 230 on back (volts?) it's pretty new I got it like 5 months ago
OK I can get it sort of working when I go into the BIOS and set it from 8x to 4x. The graphics advanced setting was showing 4x. The motherboard is SUPPOSED to support 8x but it just won't work at all in that mode. It works for awhile in 4x mode. No specific amount of time I have current drivers on everything! Then the same old thing happens! Monitor goes to energy saving mode or computer restarts. On restart can use it again for a limited time again, and then the mouse pointer kinda goes funny and it freezes. It goes pixalated and if I move it this 'block' goes up and down in a line only. Most of the time has been trying to start AOL (my ISP) it goes off then. Have tried different rates (went down to 16 bit) and desktop sizes (went down to the one above 800x600) no go. I took the refresh rates to 60, tried everything. I have taken it out again.
I don't know if it a motherboard problem, the graphics card or a combo! I just paid £54.99 for the graphics card, and don't want to waste it! What should I do. It's really frustrating!

Airport base station and connectivity problems

Hi all,
Heres what I know about my internet connectivity issues. I have a cable broadband (Motorola Surfboard) modem and I'm fine getting a connection when I am hooked directly from the modem into the back of my G4.
The wierd thing is that when I have my Airport (old school flying saucer shaped one) hooked up between my G4 and the modem I don't even get a signal on my tower any longer let alone my laptop. I have an ethernet cable running from the port on the base station with the circle of dots to my modem. I have a ethernet cable running from the ethernet looking port (arrows and dots) on the base station to the G4 tower.
What I don't get is why I wouldn't at least be still getting a signal to my tower? All of the appropriate lights on my modem are still lit up. I took it in a few days ago to an Apple store and the guy at the Genius Bar confirmed the Base Station is working fine. Why does my computer now not like being hooked up thru my base station? I've checked all of the network settings and all seems to be fine.
Any help or ideas will be appreciated. This is driving me nuts.
Thanks,
Vance

I may have misunderstood your original question. If you want to use both your older Airport as well as the newer dual band one, you certainly can, but first describe which model your older Airport is and what specifically you wish to accomplish by using both.
There's no advantage of keeping the older one in service unless one Airport base station is unable to create a wireless network with sufficient range for your needs. There are as many as three different ways of doing that depending on which older one you have: a Wireless Distribution System (WDS) which can only use 802.11b/g, an "extended" network, which can only be accomplished with an 802.11n network, or a "roaming" network in which the Airports are connected to each other using their Ethernet LAN ports. This last method is the most preferable, but obviously requires that you run a cable between them.
Use Airport Utility to configure the Extreme. Read about designing networks in the Apple AirPort Networks manual.
In any event you don't need to use both Airport base stations if all you want to do is have a wireless network that can serve both your iMac and your Powerbook. Any Airport base station Apple ever built can serve both. The newest Extreme just adds more features.

HELP - Airport Extreme Disconnect and Connection problems

Hi everybody,
I recently (~2 months) got an Airport Extreme (Early 2009 Model). I was very happy with it, and everything worked fine, until a few weeks ago, when I started getting the following problems.
First, my iTouch wouldn't connect automatically anymore and when I tried connecting, it would say "Unable to Connect" around 5 times until I could connect, and then I would remain connected (full three bars) with internet for about 30 seconds, and then my connection would suddenly drop to 1 bar and my internet would stop working, and then it would eventually disconnect. May I just say that this was happening when I was sitting right next to the WiFi.
Secondly, all of the computers (both Windows and Mac) started having a similar problem: Connection Time Outs around five times until I can connect, and eventually signal dropping without the computer or anything moving. (BTW, the cable connections work fine, it's the the WiFi that doesn't work).
I tried changing channels, enabling Interference Robustness, and reverting to previous software updates,and also eventually Hard Reseting the box, without any results...
What could be my problem, and how could I fix it please?
Thanks a lot...

Roger, you must be psychically broadcasting this because I just seconds ago posted the following on another thread...
I hope I am not "typing" too soon but I seem to have identified my wireless problem. After trying EVERYTHING in the world to try and figure out why my own network wouldn't work, I had a flash of inspiration. I changed the Channel setting in airport utility from "automatic" to 11. I just picked 11 because I liked the number - no other reason. Now, I am wirelessly connected again. I do not know why this worked; The channel setting has been on automatic for months and worked fine until late Friday night. So those of you who have been fighting this issue, give the channel fix a try. Your mileage may vary and may the force be with you.
(Will post this on another thread pertaining to this subject too. If I can keep just one soul from sacrificing many precious hours on this frustrating issue, then I will consider myself one good deed up on my Karmic calendar.)
