AE: green light, wireless n, net is slow and drops

I bought an Airport Express for my girlfriend. She has a 10.4 Core 2 Duo Macbook with N enabler installed. I think the AE is running the latest firmware (7.4.1).
The internet is terribly slow and cuts in and out. The light is always green. I've tried the usual fixes (hard reset, channel, turned off N and tried g, etc). I have yet to try it with another computer but I have a mini I can test it with. Internet is fast via ethernet.
Suggestions? Anyone else experiencing this problem? I don't know what the heck else to do.

I gave this a shot as part of ruling out the modem. The modem connected to the computer via ethernet is very fast. In fact, the modem was usually switched off overnight (but not the AE).
An old wireless g airport express was fast and never had any issues. Unfortunately it was broken.

If multiple people are seeing the same problems after making the same changes it is hard to believe that each problem is fundamentally different. To say that a change is specific to a single configuration implies that every computer and every operating system installation are different. This is not rational. Treating each problem individually fixes one problem. Finding the root cause fixes all the problems. I am familiar with finding root cause of communication systems - in particular mission critical spacecraft command and telemetry links. That experience teaches me to break the problem into pieces. My troubleshooting indicates a very high packet loss between my computer and my wireless router. In the exact same configuration with with two other devices i see negligible packet losses. i can go outside my home network and see the same ping and traceroute evidence in comparing the devices. That rules out my ISP, my email provider and pretty much isolates the problem to the router Mac link. Is this thinking flawed? Can you suggest additional tests I can run to further isolate the dropped packet problem? Further, no hardware has changed in my configuration. The only change is the upgrade to 10.8.3.
In posting to other threads I am trying to find if there is evidence of the same problem and to determine if there is any other way to gather evidence, and perhaps suggest ideas that folks might double check their fixes. In doing so you aggregate the problem and not decimate it. The problem in this thread may not be solved if a packet loss is still present. I am seeing packet losses as high as 60%; an iPad at the same location is seeing less than 0.1%. The network connection will work with high packet losses. You know that is what TCP/IP does but why accept 20%, 10% or 5% packet loss if you know it should be much less than 1%. The problem can only be determined if it is tested.
I have created my own thread - I linked to it.
If you prefer to not allow comments on closed threads I would suggest closing the threads to editing. In the future I will link from my thread to the solved one however if my thread finds a better solution there will be no way of pointing from the closed thread to a better solution.
My apologies for attempting to perform a methodical root cause analysis.

I have just returned from a business trip to China and my Macbook is not well. My internet connection is very slow and drops out intermittently. Is there a utility I can run which might clean it up.

Hello,
I have very similar problem. Suddenly Firefox stopped work - It was working few days after ver. 4 update. I was looking everywhere for some solution but nothing worked.
- uninstalled firewall - did not worked
- added full exception for Firefox into the firewall - did not worked
- Firefox reinstall - did not worked
- Firefox complete reinstall (registry included) - did not worked
- IPv6 diseabling - did not worked
- diferent proxy options (no proxy, system proxy, autodetect proxy) - did not worked
- new firefox profile - did not worked
- complete coockies, history... deleted - did not worked
- there is only one solution which partly works - I have used public proxy addresses for Firefox but the ping is (750ms), down/up (0.8MB/0.2MB originaly (10MB/2MB) and yes I have tried different proxy server from different countries from my included.
- IE is working perfectly and without proxy
- other companies browser - did not worked too
- only IE is working
- I have used three different malware, trojans, spyware, anti-virus programs and nothing
It seems to me as hopeless situation or very clever move from Microsoft, I am forced to use IE - at least this works
Any ideas, solutions?
System Windows 7, firewall Comodo Internet security
Thanks everyone for the help

My original iPad is very slow and drops the signal to websites and videos all the time now. Does it have a virus or extra junk on it to cause this or is it just so old it can not handle the extra stuff on websites these days??

My original iPad is slow and drops web pages and videos all the time now. Is the software just too old to handle the technology changes on the websites and video or is it a virus or junk in the iPad causing this? I have plenty or storage left on the iPad like 18GB. Sure would like to know. Maybe it is just too old to handle things now?

IIf you are running iOS 6.1.2, you could not be using the original iPad. No matter which iPad and what version, try these basic troubleshooting steeps and see if it helps with the performance.
Go to Settings>Safari>Clear History and Website Data. Then close all apps.
In order to close apps in iOS 5 or iOS 6, first tap the home button once. Then tap the home button twice and the recents tray will appear at the bottom of the screen. Tap and hold down on any app icon until it begins to wiggle. Tap the minus sign in the upper left corner of the app that you want to close. Tap the home button twice.
In order to close apps in iOS 7 or 8, you have to drag the app up from the multitasking display. Double tap the home button and you will see apps lined up going left to right across the screen. Swipe to get to the app that you want to close and then swipe "up" on the app preview thumbnail to close it.
Now reset your iPad. Reset the iPad by holding down on the sleep and home buttons at the same time for about 10-15 seconds until the Apple Logo appears - ignore the red slider if it appears on the screen - let go of the buttons. Let the iPad start up.
You can also try resetting all settings. You will not lose any data, but most of the device settings will have to be entered in the settings app again. Settings>General>Reset>Reset all Settings.

Brand New Airport Express-Green Light Wireless, Dead Green Wired

I just bought a brand-new airport express device. I have a cable modem connected to a dual band AirPort Extreme base station in my basement. My house is wired with Cat5 Ethernet cable. In a far bedroom, I am replacing an airport express-N (previous model) that was hard-wired to the Extreme. Always worked perfectly in extending and supplying 2.4ghz band wifi to that part of the house. I bought the brand-new AirPort Express to utilize the dual band bridge.
After many hours of trying, this new airport express will only work properly if I do not plug in the Ethernet cable. It seems to be performing well, but i was under the impression that an ethernet cable should be used to physically connect the AirPort devices each other.
Currently, in this wireless setup, I do have both bands available. I feel that if I used the cable, I would have much stronger better signal.
Interestingly, when I do ether-connect the airport devices together. My AirPort Utility looses all of my AirPort devices and shows (with a yellow dot) that my Internet (modem) is not available. At the same time, all of my AirPort devices continue to show a green light. I am unable to connect anything with any of my wireless devices.
Also, when everything seems to be working fine, my AirPort Utility does depict the wireless set up with a dashed line between the two AirPort devices representing that it is wireless connection.
With my last AirPort Express, a wireless set did extend the range, but only while slowing everything down. An ethernet cable, when introduced, made everything work perfectly, during which time the AirPort Utility depicted that setup with all solid line indicating wired connectivity.
I would appreciate any feedback from anyone who might be able to tell me why when I introducing ethernet to the new AirPort Express, it takes down the entire wireless network.
Hi, of course, try all of the normal troubleshooting suggestions. I recycled all devices I have rebooted everything.

It's always a good idea to do a complete power recycle when switching out network components ...
Try the following, in order, checking for Internet access after each step, until resolved:
1. If the modem has a reset switch, use it to reset the modem. Wait at least 5-10 minutes for the modem to initialize.
2. Remove power from the modem. If it has a backup battery, remove this as well. Wait 5-10 minutes. Replace the battery, and add power back to the modem.
3. Perform a complete power recycle of your network components as follows:
Modem/Router Power Recycling - Quick
o Power-off the modem, 802.11n AirPort Extreme Base Station (AEBSn), & computer(s); Wait at least 5 minutes.
o Power-on the modem; Wait at least 5 minutes.
o Power-on the AEBSn; Wait at least 5 minutes.
o Power-on the computer(s)
If this fails to get the modem to "recognize" the Internet router, then try the "Full" version.
Modem/Router Power ReCycling - Full
o Power-off the modem, AEBSn, & computer(s). (Wait at least 30 minutes. If possible, leave the modem off overnight.)
o Power-on the modem; Wait at least 15 minutes.
o Power-on the AEBSn; Wait at least 5 minutes.
o Power-on the computer(s)
4. Contact your ISP to have them perform a "modem reset."

Slow and dropping connection WRT300n v 2/WMP300 v 2

Slow an dropping connections on WRT300n v 2/WMP300 v 2 updated with latest firmware/driver.
Before update it gave a speed of 3-4 mbit/s and after update about 30 mbit/s, this is just a bit better(10-13%) than the D-link products (604/AP2000+/DWL-G510) i intended too let go of old age.
For E-mail and surfing the web this speed is ok, but sharing files and use a mediacenter its not ok.
Next problem is that after about 30-40 min of full load the router just dropps all connections and reboots or what ever.
The Linksys products WRT300N/WMP300 is not a what a expected it too be

WRT54GX2 slow and dropping

Hi, I currently have a WRT54GX2 router which has never given me cause for concern before. I am connected wireless to my Dell laptop running Vista Business. About a few months ago I noticed that the connection had seemed to slow down a bit, but without time to worry about it, I ignored it. Then, I started having more severe problems. My internet connection seems to cut in and out. It usually lasts no more than a minute, but it has been happening so frequently that it is getting ridiculous.
I upgraded the firmware to 1.01.22 and that seemed to be the miracle cure, but it only lasted for maybe 5 days and the problems returned. I also tried turning off the TCP Window Scaling which did not seem to help, and eventually while running a diagnose/repair it prompted me to turn it back on so I did.
Also, it seems to get even worse if I attempt to download anything. It's /very/ difficult to ever get anything to fully download, which is kind of a problem (obviously).
Any suggestions would be appreciated! Or perhaps it's not even the router posing the problem... could it be a problem with my wireless card or the like? I have updated drivers and all so I'm not sure if that would be a cause...
Thanks in advance!

Thats good, know we know that the computer is clean and not causing the issue, we will move to the router and here are some steps that you can take a look at.
There are many reasons for a poor wireless connection, and many ways to solve this issue.
1.      Give your network a unique SSID and do not use Linksys and set your SSID Broadcast to enable.
2.      You can also try A different channel. There are 11 channels and 1, 6 or 11 is better
3.      You can try raising your router approximately 4-6 feet above the floor and make sure the antennas are vertical.
4.      access your wireless software by going to your Profile or preferred networks, if any are named Linksys or ones that you do not know please delete them. Go to the settings or properties and check the information to make sure it is correct.
5.      See if there are any updated drivers to download.
6.      Try to use WPA encryption if you can
*** As always upgrade to the latest firmware
Good Luck,
Ttech

Wrt320n connection slow and dropping

I am having trouble with the connection being slow to load and also dropping. I get a message 'Problem loading page' 'The connection to the server was reset while the page was loading.'
Also have an HP c309a printer that the router is messing up. The printer hangs up if its been idle for a while. Have to unplug it to get it to work again. If I unplug the router from the printer, it works fine.
Carol

Login to your Router setup page and then click on the Wireless tab and below Set the Radio Band to Standard-20MHz and change the Standard channel to 11-2.462GHz...Wireless SSID broadcast should be Enabled and then click on Save Settings...The click on the sub tab "Advance Wireless Settings" and below Change the Beacon Interval to 75,Change the Fragmentation Threshold to 2304,Change the RTS Threshold to 2304 and Click on Save Settings...
Now see if you can locate your Wireless Network and attempt to connect...

Broadband speed slow and drops

Hi Just got Sky broadband and not really happy with the speed i am getting, it goes between 8 down to 2, really annoying especially when my neighbour can get between 12 & 13!!

I don't know whether or not Sky still do the 10 day line training when your speeds can vary a lot, I thought I'd read on here that they stopped doing it.If they don't do it then your noise margin is too high especially upstream. Lift the phone, press any one number on the keypad and listen for noise on the line hissing or crackling. For a quiet line test dial 17070 option 4 and if you do have noise try plugging just a phone (no filter) into the test socket.If the noise is still there phone Sky and report a line fault (noise) not a broadband fault.

MacBook Pro 2011 not charging green light on charger

Bought my MacBook Pro early 2011, really took care of it, no problem till now. Was using it last night as usual and when plug in the charger this morning there's green light but not charging, usually when charging its orange, the battery level on the side is one green light blinking. Its completely dead and I can't power on. I found a way to power on the machine (press power button for 10sec and plug in charger while keep holding the power button for another 10sec) it powers on using AC but now the battery is not detected and no blinking light on the side and theres X icon on the battery! Have done SMC reset and all still no fix! found this somewhere on the net, apparently to bring dead batteries back to life we have to charge it with 85w charger, is it true? I mean if its true I don't mind getting a new 85w charger, or do I have to change a new battery since it's 3++ years old? Pls Pls Pls I need help big time..

Hi Ralph, thank you for responding.. I used to see those information like, condition, cycle count, etc before, but now its not showing up probably the battery is not detected. Any ideas? Thanks again..

Network Diagnostics gives green lights, but machine still won't connect

I am using a AE(N) base station and wireless network, and as far as I know, no settings have changed. My mac mini has an IP address can send and receive mail, but neither Firefox nor Safari can load any webpages and apps that try to connect like software update don't recognize a working connection. Network Diagnostics give me green lights all the way through "Server" and multiple other machines still work on the same network. I have removed the network login info from the mac mini and erased the mini's connection access from the base station and started over. Mini has no change, and the other machines are still fine. I tried creating a guest network and connecting to that, but it didn't help. I'm running out of ideas to trouble-shoot the problem. Any advice is appreciated.

In the Network panel of System Preferences, if you click on the "Advanced" button for your AirPort connection, then on the "DNS" tab, what do you see for "DNS Servers"? How does that computer with the same settings for the computers that are working?
What do you mean by the statement that "I have removed the network login info from the mac mini and erased the mini's connection access from the base station"?

Green light does not flash any more

Hello guys can you please help me my green light does not flash any more and my blackberry has been slower than the word slow since ever the light is not flashing

Does the shuffle still play?
When it is connected to USB and the light is blinking orange, that mean DO NOT DISCONNECT - Eject shuffle in iTunes before physically disconnecting. If you do that (click the eject button in iTunes), but leave the shuffle connected to USB, the shuffle's light should become solid (not blinking). Solid orange light means shuffle is charging. If it's red, the shuffle may have a problem with charging. Does the SOLID light eventually become GREEN (battery fully charged)?

Aebs stops working, but still shows green light

I will be connected to the aebs when it will suddenly and without warning disappear. No wireless devices can see the aebs and anything connected via ethernet loses its connection. The device still shows a solid green light, but it must be unpluggeed and replugged to reset it. Sometimes it will come back for a couple of days, sometimes only for a few minutes or even seconds. Originally I was having problems with a wireless telephone, but I replaced that and it seemed to be fine for awhile. Is it possible I just have a bad aebs?

Have connection to base station, solid green light but no internet ??

Hello,
At my wits end. I have a a brand new Airport Express, a brand new Dell laptop running Vista Home Premium and an older model Westell Wirespeed DSL modem. Although I have a solid green light on the Airport base station, and have no problem communicating and printing wirelessly, I cannot connect to the internet. All indications from the Airport Utility show a normal connection with a signal strength of 'very good' to 'excellent'. I configured Airport to DHCP, which is what my ISP (Verizon) provides. Sometimes upon startup, my computer first tries to connect to an 'unknown network' and I have to manually switch to the Airport network I created. I've been through this at least half a dozen times, resetting the modem, the base station and re-setting up the network but no luck getting on the internet so far. What am I missing here? Thank you!

If anyone happens to stumble on this, I solved the issue on my own. The TC/IPv4 protocol on the PC's wireless network properties was set to a static IP address. Once I reset it to dynamic, it worked fine.

My IMac has stopped seeing the keyboard. I have changed the batteries and the green light comes on saying it is looking to pair with the IMac but without success. I am left with the IMac switched on and I am unable to enter a password.

I have been using my IMac without a problem when I left it and went back to enter the password the IMac did not see the keyboard. I have changed the batteries and the green light comes up on the keyboard and then starts to flash indicating it is looking for the IMac but nothing happens. I have tried another set of new batteries with the same result. Is there any known problems in this area. The IMac is 5 months old.
Thank you for any help

What operating system does your iMac have? (please always post your operating system to prevent confustion).
If it's pre-Lion you will have to set Mail up manually:
Entering iCloud email settings manually in Snow Leopard or Leopard
Entering iCloud email settings manually in Tiger
