EXTREMELY SLOW WIRELESS NETWORK SPEED !!!

Hi,
I have an AirPort EXTREME conected to internet and an AirPort EXPRESS which I use as a range extender with WDS. My broadband speed is (unfortunatelly) never better than 2.7 Mb/s. I have noticed that my EXPRESS station is working at 54 Mb/s transmit rate while my EXTREME is always between 5 Mb/s and 25 Mb/s, most frequently between 8 and 10 Mb/s. I tried using only the EXTREME station for better monitoring of the traffic and I found that it works even slower, somewhere around 2 Mb/s. I use WPA2 coding and a fixed channel transmission (stand-alone or in WDS).
Is there any reason why transmit rate would drop so significantly? Is there a way to force a higher rate? My transmit rates are low very irrespective of whether I am somewher in the house behind wals or right next to the antena... The internet download time is slow even for just internet pages while downloading any file is quite slow and the connection to my wireless printer/scanner is greatly affected.
Please help !
Many thanks,
Igor

Just to add some of my experiences to the debate.
I use a late-2008 TC and connect it wirelessly to an ISP supplied modem/router and a late-2008 iMac. Because of limitations with the modem/router, I had to use 802.11n at 2.5 GHz. The internet connection is via the modem/router and internet usage from the iMac is fine in all circumstances (it does not go via the TC).
Performance was pretty good with 7.3.2 but when I originally tried to upgrade to 7.4.1, TC backup became very slow and pretty unreliable. In my case, restarting the router got things going again but TC usage was always a pain. So, I reverted to 7.3.2 and ran beautifully for several months.
Then I tried 7.4.2 when it came out and my regular hourly backups became very slow, typically taking 70-80 minutes rather than 2-3 minutes. However, in contrast to 7.4.1, the connection to the TC was very reliable if slow, somewhat different to my experience with 7.4.1.
Switching back to 7.3.2 and TC was back to normal.
Being curious and having time, I decided to try changing things and see what happens. First tried dropping the wireless to use 802.11g. Result with 7.4.2 was excellent - probably a little faster than 7.3.2 with 802.11n. Tried 7.3.2 with 802.11g and that was as good as 7.4.2 with 802.11g.
Then tried letting the modem/router select the wireless channel and 7.4.2 with 802.11n became a lot better but remained at least twice as slow as 7.4.2 with 802.11g (but not 30 times worse).
So, what do I conclude from that? Not exactly sure but there would appear to be something amiss with the 802.11n support on the 2.5 GHz band for the "old" single band TC when using 7.4.2. Perhaps it is more susceptible to interference or something but when faced with identical circumstances (just switching the firmware level, no other change), it is definitely worse to very much worse.
For now I am happy with 802.11g and 7.4.2.

I have a 1st generation time capsule and an extreme b/g. Is the extreme slowing the network down

I have a 1st generation time capsule and an appe extreme b/g. Is the extreme slowing the network down? Should I dump it an get the new n version?

yes it is likely to be slowing down the network because you are using 802.11b/g
from what i recall with b/g a slow client can slow down the entire network to that clients speed.
this was the major improvement with 802.11n and Mimo. each client can be connected to the access point without affecting your speed to the rest of the network
its reccomended to get all new "N" equipment if you have the budget for it. some of those old airports and time capsules can still be worth something on amazon marketplace so you might be able to sell them
if you want to create / join / extend a netwowrk your going to probably need all "n" based equipment.
buy the new 4th generation time capsule or the new 5th generation airport they have better stronger radios
in the mean time configure your base station router to a high multicast rate, so it will prevent devices connecting to it at 1-2 mbps speeds and slowing down your network
if you have an apple care covered mac remember the airport / time capsule rule. all airports and time capsules purchased 2 years before you bought your mac to the 3 years of apple care covers them. if you do not have apple care then the standard warranty applies

Macbook Air Extremely Slow Wireless

Hello All,
Got my brand new MB-Air and from the get-go noticed extremely slow wireless performance. I did a bit of digging and here is what I found.
The MB-Air works OK with cheap (consumer) wireless APs, however when used in conjunction with the commercial APs most of which use the Atheros chipset the performance is horrible. I found that when connecting to APs that use Atheros' commercial chipset, the MB-Air connects with 802.11 G specs instead of N even when the signal metrics are excellent such as -39 RSSI.
Moreover, even With the 802.11 G connection at 54Mbps the performance is both sluggish and latent. Small file transfers have a 50/50 shot at working and large file transfers seem to die reliably. Albeit this could be an issue with Apple's implementation of SMB / Samba which is rather poor.
I have tried to turn off Bluetooth to see if my experience is different. We'll see.
I would be interested in feedback from people who are also experiencing the same poor wireless performance to learn the chipset of the AP they are having issues with.
By-the-way -- I will take a fix, if someone has come up with one. However my guess is that this is an engineering issue that Apple has to fix.
BP

Sitting side-by-side, my MBA was averaging less than 1 Mb/s on downloads, and my MBP more than 9 Mb/s. The MBP was fully ten times faster. As you can imagine, viewing videos was a ragged, unpleasant experience on the MBA.
I'm using an early wireless-N Belkin router, so it didn't show up on airport utility, thus i couldn't change channels there as proposed on this thread. But to isolate the problem, at my brother's suggestion i took both computers to a Starbucks, and observed the two computers downloading there at equal speeds. So clearly the problem wasn't with my MBA, but my router.
I went to Belkin's website to figure out how to change channels on the router, and checked for firmware updates. There was one, so i figured I'd do that before attacking the "changing channels" task. I upgraded the firmware, and with that simple fix my MBA is happily zipping along now with >9 Mb/s downloads, same as the MBP. More than TEN times faster than before. My iPhone download speeds increased more than tenfold, too.
My advice, if you're having wireless problems with your MBA: First make sure your router's running the latest firmware.

Windows Vista = very slow wireless network

I have a brand new Lenovo ThinkPad Z61p. A great machine, great performance. But Vista seems to get in its way.
The first thing I did, was to re-install Windows Vista to get a clean machine, without alle the junk that comes with it. At work, the wireless network worked just fine - but when I came home, it was so slow. I mean REALLY slow. If I turned the wireless network card off, and plugged in a cable, I was flying on the Internet. But for the wireless adapter, even a page like msdn.microsoft.com could take 3-4 minutes just to load.
I thought the issue was the drivers for the wireless network adapter, but later, in my desperate attempt to solve the problem, I removed a Windows feature called Windows DFS Replication service, which solved my problem.
This was 4 weeks ago - and now the problem has returned. I've been reading a lot of forum posts around the web. I've uninstalled some other features, disabled IPv6, disabled Vista Auto-tuning ( i did that 4 weeks ago as well)...
Nothing is working. I've also changed the default Network authentication mode, I've updated the drivers for the Intel Pro Wireless 3945abg, changed the wireless mode and a lot of things. Nothing is working.
Does anyone in here have the same issues, or does anyone know what is wrong?

I picked up a new IBM ThinkPad T60P (Wide) running Vista Business, and I am experiencing the same problems with an extremely slow wireless connection. I get the same slow performance on the wireless network in my office as in my home.
The second I disable the wireless and plug in the cable directly to the router (ZyXeL) everything runs perfectly. I also tested connecting an Apple AirPort to the router (via cable) and connected directly to the AirPort as an access point instead of connecting to my normal wireless network, and then everything was working just fine for some reason (almost as fast as when I connect directly to the router via cable)!
The really weird thing is that I get really quick download rates on at least one website (www.dailyrush.dk) where I can download files at 1.1 MB/s (I should have 15 mbit downstream). The web pages of that website still load pretty slow though when I'm browsing. Most other websites that I have tested load insanely slowly, both when I'm just browsing the pages and when I'm downloading files. For example a 1024 x 695 pixel JPG on Flickr.com might take several minutes to load, or simply time out. The Google front page sometimes takes 15 seconds to load.
I have my old laptop parked right besides the new one, both connected to the same router on wireless, and the old laptop (IBM ThinkPad T41 running XP) performs fine - downloading anywhere from 10 to 100 times faster!
It also takes forever to connect to VPN, perhaps 15 or 20 seconds on the Vista laptop and no more than 2 seconds on the XP machine.
When I ping www.google.com in a command prompt I get some packet loss (between 25 and 100 %) but reasonable ping times averaging about 45ms which is the same as on my old laptop.
I have tried pretty much everything:
Disabling Windows Firewall
Disabling TCP/IP v6 and those other entries in the wireless adapter configuration that are new in Vista
Disabling security on the router entirely
Changing security on the router to WPA and WPA2
Changing the channel on the router (tried several available channels)
Switching between 802.11 a/b/g modes on the router
Booting up in safe mode (heard that worked for someone with a similar problem)
Updating the wireless adapter driver to the newest version
Installing all available updates from Windows Update
Moving my laptop really close to the router (duh)
Uninstalling MacAfee
Uninstalling Bullguard
Uninstalling a bunch of pre-installed IBM stuff
I have come across several threads online where people have had the exact same problem and solved it by uninstalling the pre-installed MacAfee software. My laptop came with MacAfee too but I uninstalled it right away and installed Bullguard instead. When I noticed the connection problems I uninstalled Bullguard too, but little did it help.
I really hope that someone can help me out here ... I'm kind of running out of ideas :-( Thanks in advance.
Cheers,
Stefan

HT4259 Q: Can I use an older Airport Express-g router (not -n) to extend my Airport Extreme-n wireless network? If Yes, are the instructions the same as for adding an Airport Express-n router?

Q: Can I use my older Airport Express-g router (not -n) to extend my Airport Extreme-n wireless network? If Yes, Are the instructions the same as for adding an Airport Express-n router?

If you want to extend, using wireless only, the 802.11g Express doesn't support this.
However, if you want to use bridge mode over Ethernet or Powerline adapters then this is supported.

Extremely Slow Wireless Performance on an Extended Network

Hi
My network setup consists of a Time Capsule (early 2009) wireless network that is being extended by an AirPort Extreme (early 2007) which has an Xbox 360 connected to it via ethernet.
1) Everything seems fine on the MacBook Pro (wireless N) when connected to the Time Capsule and I can get the full speed of my broadband connection (8Mbit). However, when the MacBook Pro connects to the AirPort Extreme, in another room, my broadband speed drops to around 2Mbit, however the transfer rate usually remains unchanged (between 78 and 130).
I know it has nothing to do with the positioning of the base stations, as when I turn off the AirPort Extreme, the MacBook Pro, in the same room, has the full internet speed.
This is really annoying as I rely on my Xbox 360 for heavy video streaming and content downloads.
2) When the Xbox 360 is downloading something, any internet served by the AirPort Extreme becomes totally unusable and dead.
3) Additionally, the AirPort Extreme sometimes insists on extending the 5Ghz network from the Time Capsule which only provides a rate of around 10.
Please help me!
Thanks

To insure that your AirPort Extreme is extending the 2.4 GHz band from your Time Capsule:
Open AirPort Utility, select the Time Capsule and click Manual Setup
Click the Wireless tab below the row of icons
Click the Wireless Options button
Assign a separate name for your 5 GHz network. (By default, AirPort Utility will automatically add "5 GHz" to your network name.)
Click Update to save your changes
Then check to make sure that your AirPort Extreme is setup to extend the 2.4 GHz band from the Time Capsule, not the "5 GHz" network.
If you perform a Factory Default Reset on the Time Capsule, it will not affect your stored backups on the Time Capsule disk.

Extremely slow wireless printing with HP Photosmart Premium C309g-m

I'm seeing extremely slow print speeds when printing wirelessly from a Mac or a Windows XP system to a new HP Photosmart Premium C309g-m printer. The printer begins printing immediately when I request a print, but it only prints one line. It will then take about 15 minutes to print the rest of the page, printing each line after a very long pause. Demo page printing doesn't exhibit this problem, only documents from programs like Word 2008, Safari and Firefox (tried firefox on PC and Mac) are affected.
If I connect to the printer through a USB connection it prints fine, so this problem appears to be with wireless printing only.
Printer: HP Photosmart Premium C309g-m
Computer: Mac mini (Late 2009 model) (also tried a Windows XP laptop as a comparison, using latest drivers from HP's website)
OS: Mac OS X 10.6.2 with all available updates installed
Computer connection method: Wired Ethernet connection to wireless router
Printer drivers: version 2.2.1 (Apple supplied, HP drivers never installed as system shipped with 10.6)
Wireless router: Apple TimeCapsule (Early 2009) 1TB, running in a/n and b/g modes on 2.4 and 5GHz. TimeCapsule is in bridging mode as the DSL modem handles DHCP service
Encryption: WPA2 Personal, no MAC filtering or hiding of the SSID.
IP addressing scheme: All addresses are handed out by DHCP server with no reservations of any kind
The TimeCapsule is sitting three inches from the printer and the printer indicates full signal. Connection of the printer to the wireless network and setup of the printer on the Mac went without a hitch. Only when printing a test document did we discover the problem. The wireless network is behaving as expected when accessing the Internet from both Mac and Windows devices (tested with a Dell laptop running XP and a MacBook running OS X 10.6.2), so I don't see any overall problems with the wireless network.
Attempted remedies:
1. Rebooting and powering off, waiting, powering on computer
2. Resetting the print subsystem, turning the printer off and on again and reinstalling the printer
3. Unplugging power from the printer and letting it sit for several minutes before trying to print wirelessly.
None of these worked.
This question was solved.
View Solution.

I don't think there is anything wrong with the DSL modem HW. There might be an issue with how print data is being routed though.
Please try the second experiment where you blank-out the default gateway and DNS entries from the printer's internal web configuration page. Open the printer's internal web page by browsing to its IP address. Select Networking and then Wireless (802.11). Under the IPv4 Configuration tab, select Manual IP:
For Manual IP Address, use the existing printer IP address.
For Manual Subnet Mask, use 255.255.255.0
For Manual Default Gateway, leave blank. This is important.
Select Manual DNS Server:
Leave both the Manual Preferred DNS Server and Manual Alternate DNS Server fields empty. This is important.
Press Apply.
Turn off the DSL modem, the printer and all computers connected to your network. Wait 60 seconds then turn on the DSL modem and then turn on the printer. Then turn on the computers. See if this corrects the printing speed.

Macbook (C2D) + D-Link DIR-655: Slow wireless N speed

When I transfer a large file (around 1.3 GB), the speed fluctuates between 1.5 MB/s (12 Mbits/s) and 2.5 MB/s (20 Mbits/s). The Macbook according the Network Utility is connected at 130 Mbit/s. It's supposed to be at 300 Mbit/s. That's one problem. The other is, even if it is connected at 130 Mbit/s, it's still extremely slow.
I am transferring files to/from a Linux Ubuntu server over Samba. When I connected through the wire, it flies, so I know it's not the configuration on the server. It's the wireless driver on the Macbook.
What kind of average speeds of file transfer on the LAN are people getting? Can you please share? Is it normal to have wireless N and have 12 to 20 Mbit/s speeds?
Can anyone from the Apple Wireless Driver team comment on this?
Many thanks,
Roy Assaly

Some more information about the speed. It looks like playing with the TCP Window has dramatically increased the speed. Here is the data:
Macbook:
========
$ iperf -s
Server listening on TCP port 5001
TCP window size: 256 KByte (default)
[ 4] local 192.168.0.100 port 5001 connected with 192.168.0.101 port 37617
[ 4] 0.0-10.1 sec 74.7 MBytes 62.1 Mbits/sec
Ubuntu Server:
==============
roy@ubuntuserver:~$ iperf -c 192.168.0.100
Client connecting to 192.168.0.100, TCP port 5001
TCP window size: 16.0 KByte (default)
[ 3] local 192.168.0.101 port 37617 connected with 192.168.0.100 port 5001
[ 3] 0.0-10.0 sec 74.7 MBytes 62.4 Mbits/sec
So I knew that the TCP stack itself is fine. It had to be Samba. I used this for now:
socket options = TCP_NODELAY SO_KEEPALIVE IPTOS_LOWDELAY SO_RCVBUF=65536 SO_SNDBUF=65536
That got me to around 4.0 (32 Mbits/s) to 6.3 MB/s (50.4 Mbit/s) fluctuations. If anybody has better numbers, let me know.
Thanks!

Extremely slow wireless xfer from Macbook to USB drive on Airport Extreme

I have tried to set up my external 1TB seagate USB drive to my AE for wireless network storage (only 1 computer on network, but I also have an AppleTV). If the drive is connected directly to my MB the transfer speeds are fine, but when I try to go wireless the speeds are extremely slow - to the point of unusable. I am sure these issues have been discussed previously, but I cant find an obvious solution. Is there anyway to run network diagnostics to see what my MB->AE transfer speeds are and what my AE-WWW speeds are? I dont recall the cable bandwidth that I get from Time Warner - but it is one of the faster options.......

There are at least two explanations for this: (1) Your wireless connection is like to be slower than a direct USB connection. (2) Apple base stations are quite when serving connected disk drives. One reference cites 10-30% of the speed of a directly-connected USB drive.

I wouldn't expect that to be a factor in the performance you're seeing.

Wireless Networking Speeds

I'm curious what governs the speed of wireless networking - both as it concerns accessing the internet and as it concerns accessing other computer's files on the network. I understand the internet connection facet - we have a 1.5M DSL connection with about 1.2M realized.
So, I only recently connected my MDD 1G Dual wirelessly to our home/home office network. I have an Airport Extreme card with a boosted antenna for it. Using iStumbler it shows about a 70% signal strength.
I have noticed that accessing my G4 450 (downstairs) really varies regarding how long it takes to mount as well as how long it takes to access files. A long time is a few seconds (10 or 15 maybe), a short time is almost instantly. Makes me wonder what the governors are. Likewise the speed accessing the internet varies, never real slow but sometimes very fast.
I'm usually the only one on the network, sometimes my wife or children may be on the FP iMac or Cube scouring the web.
Processor speeds, amounts of Ram, number of network users, ????? - any insights appreciated.

Haven't compared to the Airport N card, but the B ones have better range/speed than the original B Airport cards, the G ones have better range/speed than the G Airport cards, would fully expect the N ones to be better two, but being external gives them an unfair advantage, because small changes in Location can make a big difference.
Oh, if you only have USB1.1, then you won't get G or N speeds
Here's what the Utility looks like, for old people that like to actually know what's going on:-)

BTW, not that I;m suggesting it, but those Airport cards have been going for more than NEW most places!

Slow wireless network since Vision upgrade

I was "upgraded" to the new look vision on Wednesday the 5th of June. The next day I noticed that my iPhone 5 and Nexus 7 tablet was getting a very slow wireless connection. I reset the hub but the problem still persisted even though it was showing a full signal.
I then changed from BBC1HD to the BBC1 freeview and the phone and tablet sprung to life. I changed back to the HD channel and the wireless crawled to a stop. I can now replicate this everytime.
My BTHOMEHUB3 is connected directly to the Vision box via a 2m ethernet cable (yes I have tried replacing the cable without success and have tried connecting to different hub ports). Speedtest indicates a download speed of 76mbps download and 15 mbps upload. When I switch to the HD channels the download speed drops to 58mbps with no change to the upload speed, so I dont think the speed is the problem.
I am hoping that someone here has experience with this problem as it has me baffled. The call entre suggests I leave the vision box and router switched off for an hour before reconnecting and to call back if that doesn't sort the problem (it didn't) I am reluctant to call back because the next person I speak to will just have me going through the same crib sheet again.
Mant thanks.

Quite seriously, the servers themself are really the least likely
culprit here. Everything points to a much more wdespread problem
affecting pretty much everything on the network. That could be the
network itself, or some machine that has crapped out and overloads the
net, something like that. NW65SP8 / BM3.9 is extremely stable, including
all included drivers.

I am desperate!! slow choppy network speeds (not actual inability to cnnct)

I have a 13" macbook air that has the following problem: I can connect to wifi networks (including at home WPA and also tried WPA2 settings) but even though I may get proper speed at first, I soon lose that and it becomes much slower and choppy (if I open activity monitor I can see the speed going up and down like crazy...). My internet speed at home is 12mpbs set by my provider. When I perform speed tests (vis speedtest.net or downloading files from other speed test sites) on my windows PC that is also on this network I get the full download speed. However with this MAC while I initially did get the full speed, it is now down to an average of 3-5mbps and the activity monitor, again, shows choppy behavior so it will be at 8 then at zero almost and then up and down again but never near the full speed. I tried to connect to other networks and I have the same problem - once this happens it stays. I tried removing the airport connection in network preferences and adding it again it does not help.
I TALKED TO APPLE AND HAD MY COMPUTER TESTED BY THEM - they didn't find any hardware issues (they said it was fine - but it isn't) but they still replaced the airport hardware in the computer - both the chip and the antenna (which meant replacing the entire screen). I brought the computer home, ran a speed test and everything was fine. I thought GREAT but then something happened and the problem returned. What I did (which I think was unrelated) was connect via SMB to a PC at home and I tried to stream a movie file. I noticed it kept 'pausing' so I opened up activity monitor again and to my HORROR I saw the choppy wave with network speed very inconsistent going up and down like crazy... I tried connecting to my slingox using the sling web access after disconnecting from my home PC but got partial speed and lots of drops too. I tried the speed test again multiple times, nothing seems to work.
SO I don't know what to do at this point. I have 10.6.6 running. I heard something about a firmware update but I am new to mac so not sure how to even do that or what else I can do to solve this problem or what is causing it. BTW - logging in now from the guest account still does not fix the issues and they remain the same.
I am desperately looking for help!!
Thanks a lot!

Have you been able to reproduce your problems on other wireless networks other than at your house? It appears you are saying that this occurs on all wireless, but I'm not sure from your comment. If it's only at home, it would appear to be a compatibility issue between your wireless access point and the Macbook Air, which isn't uncommon. Sometimes a firmware upgrade to the access point can fix it, sometimes it might require switching to a different brand of access point. It would be great if you could borrow (or buy and return) a different access point/router to test. An Apple airport would be the best to use of course. Not the easiest solution, but lets you help rule out a hardware issue with your air.
My isp provides 15mbps but my wireless devices such as my iphone, ipad, laptop usually only get 6.5-8 mbps when testing speeds to the internet. I don't expect it to be as good as the wired due to interference, signal, etc. I don't get the choppy behavior however. Firware updates from Apple will appear in the same manner as standard software updates. If there is one available for your system it should appear when you check for software updates. That being said, I believe you can also manually download them from the Apple site.

New Airport Extreme N wireless network setup questions (WDS, D-Link)

I have finally been able to set up my Airport Extreme N network after numerous attempts over the last few weeks. I was getting a very weak signal in front of the house where my wife's G4 is connected wireless to an old Airport card and where all the systems (XBOX 360; Wii and PS3) are also wirelessly hitting the network.
The current configuration is as follows: In the office in the back of the house I have an Airport Extreme N basestation connected to the cable modem and have three workstations (One Mac and two PCs) wired to it. I set up a WDS network, so I set up the Airport Expresses as remotes. In the living room I have another Airport Extreme N basestation (as a remote as well) that is hooking up to the XBOX 360, Wii and PS3. I have enabled WEP security (not effecting the XBOX 360 since it is now "wired"). Here is the weird thing - I have a PC laptop with a D-Link Xtreme N card ( DWA-652) that cannot connect to the network. I enter the WEP password but it does not connect. Am I missing something on the basestation setup? Do I need to add the MAC address of the card anywhere. When I use the laptop's built in wireless it connects with no problem. By creating a WDS network did I disable the n functionality of the base station(s)? I am a lttle condused.
Also, prior to going to an all Apple wireless network setup, I bought the D-Link Xtreme N Gigabit Router (DIR-655). I was regretfully about to return it to Best Buy but I had an idea which may or may not work. I know that the D-Link does not support WDS but if I was to set it up as the main router and added the "main" Airport basestation as a wired bridge could I maintain the WDS network? The reason I ask this is because I would love to keep the gigabit for the wired machines in the office. Also, I am wondering if the D-Link notebook card is incompatible with the Airport network.
All I know is that I have spent alot of money and sleepless nights just trying to set this network up but thankfully Best Buy has a thirty day return policy so I will return what I can't use.
I appreciate any help and advice anyone can give me.
Thanks.

Hello!
I have noticed that some manufacturers (Linksys and possibly D-LINK) only accept upper-case WEP keys only.
This drove me nuts when trying to integrate a Linksys PC PCMCIA card into my old "g" network.
As far as using WEP, it's bad and broken; but I understand that your choice of security is limited to the devices that you are trying to network.
For what it's worth, I have my network set up with the AEBS 'n' connected to my Cable Modem, with one of the ports going to a gigabit switch for my wired network. I then have two AirTunes set up as WDS extensions for music & Internet delivery to two separate areas. The AEBS 'n" serves up DHCP and routing for the entire network.
It works quite well; I get 54 mbits/sec for the two WDS AirTunes, and 145 mbits/sec to one of my ATV's. My gigabit wired machines see data rates of 15-27 MBytes/sec (depending on the type of transfer).
Good luck!

Does adding a second airport extreme slow the wifi speeds?

I get 17mbps from my airport base station hardwired to uverse router. On the new 5th gen extreme.used to extend network, speeds are 7mbps at best. is a second device incapable of the same bandwidth as the originating extreme?even when well within range?

My only issue is, i've not got the AE's on "bridge Mode"
That's quite an issue, since you only want to have one router handling DHCP and NAT on the network. You have two routers both trying to provide the same services if the AirPort Extreme is distributing IP addresses. Conflicts are inevitable. The AirPort Extreme needs to be in Bridge Mode.
I can't seem to put the AE back into the connection sharing option that says "distrubute a range of ip address"
This setting would be used only if your ISP has assigned multiple IP addresses to you....and the AirPort Extreme is the "main" router on the network.
"Share a public IP address" would be the setting to use.....if the Uverse router will tolerate another router on the network. Sometimes you can find a workaround, but then you have to put up with Double NAT errors and other unpredictable things on the network.
I used to be able to operate without bridge mode off the uverse router/modem but can't anymore.
Probably due to updates on both the Uverse and AirPort routers to prevent users from trying to run two routers on the same network.
Uverse routher which is impossible to figure out to reserve ip's etc for externetal devices.
Is this a Motorola router, or 2-Wire? Either should have online support for this type of basic router service.

[SOLVED] Extremely Slow Wireless on Macbook Pro

SOLVED (Hopefully forever.)
Problem: The b43 and bcma kernel modules do not get along. You'd never know this with kernels up to 3.2.14, as bcma is not automatically loaded and it is not needed with b43. For recent kernels however, it is. It in turn destroys wireless internet speeds.
Solution: The broadcom-wl driver. It used to be portrayed in the Wiki as being something to avoid, but that has changed recently. It offers a better connection and much faster speeds, but can take a little bit more effort to set up. Just a bit.
Broadcom-wl Installation and Setup
1. Install broadcom-wl from the AUR.
2. Uninstall b43-firmware if it's installed.
3. Note what broadcom-wl has put into /etc/modprobe.d. These blacklistings will ensure no interference from other kernel modules. Also make sure you're not blacklisting `wl` or its friends, if you have been.
4. Don't reboot yet. Go to /sys/class/net and use the command:
udevadm info -a -p /sys/class/net/<yourdevice> | grep address | tr [A-Z] [a-z]
(of course replacing <yourdevice> with the names of your interfaces - probably eth0 and wlan0) This will tell you their MAC addresses. Write these down!
5. Go to /etc/udev/rules.d/ and create a file called 10-network.rules. We are going to make custom udev rules so that our interfaces are matched to their proper names at boot time. Here is a template:
SUBSYSTEM=="net", ATTR{address}=="aa:bb:cc:dd:ee:ff", NAME="net0"
SUBSYSTEM=="net", ATTR{address}=="ff:ee:dd:cc:bb:aa", NAME="wifi0"
Enter the MAC addresses (in lower case!) and give them names in the NAME field. Apparently it's a good idea to choose new interface names, different from the default eth0 and wlan0. My file looks like this:
SUBSYSTEM=="net", ATTR{address}=="58:b0:35:f6:45:0c", NAME="wired0"
SUBSYSTEM=="net", ATTR{address}=="f8:1e:df:ea:99:17", NAME="wifi0"
6. Go change ANYTHING that had references to the old interface names. I had to change my rc.conf, as well as settings in my wicd preferences so that it knows what names to look for.
7. Rebuild your kernel image with
sudo mkinitcpio -p linux
(you might not have to do this, but it couldn't hurt.)
8. Save this page. Yes, the html. This is so that you still know what to do in case of problems and no internet.
9. Reboot and enjoy your restored wireless internet.

Seems everybody and their grandmothers are having internet problems since 3.3.
On a Macbook Pro, kernel 3.3.2-1.
Here is my problem: http://i.imgur.com/AcqLM.jpg
I made that image before checking the forums, but now that I've looked around I suspect the kernel.
Put up with it until 3.3.3? Or regress?

@fosskers:
Sry, I just told KDE to disable it
@all:
/proc/net/wireless looks pretty bad:
Inter-| sta-| Quality | Discarded packets | Missed | WE
face | tus | link level noise | nwid crypt frag retry misc | beacon | 22
wlan0: 0000 70. -38. -256 0 0 0 514 2 0
After measuring this, I just got kicked out (again):

Now it even refuses to reconnect. This is a full "enable wireless - try connect - fail"-cycle:

Sometimes it does not find any networks at all (iwlist wlan0 scan shows nothing)
Again, everything was fine with kernel < 3.4. (downgrading helps).
Maybe I should start compiling some kernels myself and search the regression with a bisection...

EXTREMELY SLOW WIRELESS NETWORK SPEED !!!
