Router Placement
Forum User - "Well I feel really dumb. After moving the router away from other electronic devices my speeds are back to normal. Just a heads up for anyone experiencing slow speeds, you might want to move it away from other electronics and see if that helps."
3-6' feet minimum safe distance between devices.
Placement on main level floor and central in the building and WELL ventilated is preferred. Not in basements or closets as building materials, or near by electronics devices could interfere or hinder good signal propagation.

Slow wireless speed with new iMac Intel- problem with 802.11g?

There IS a problem with the new Intel Mac, I have tried both the Intel iMac and the new Intel Mac mini and they both have the same problem with slow wireless speed (or rather it variates, if I do a ping to another computer on the network the speed goes from < 1 ms up to 1000 ms and then down to < 1 ms and so on). The older mac minis, my Linux boxes and my Windows PCs don´t have that problem. I have also read reports on the net and it appears that most users experiencing this problem have wireless card firmware version 101.3 (3.120.28.3) . A possible "fix" is to change to 802.11b on the router and then it works. No speed fluctuations and a stabile network! I know it is a bad solution, I would prefer to use 802.11g and get the speed. However I think this points to a problem with the drivers regarding 802.11g. I am starting up a new thread on this and those of you with problems, please try to switch to 802.11b and if it works let us make Apple aware of this.

Slow wireless speed with PPPoE

I'm using a WRT54G wireless router configured with PPPoE connected to a DSL router which is acting as the DHCP server. The DSL connection is 10 Mbps. I have two roommates wired to the router and me and another roommate wirelessly. The two computers that are wired directly are getting speeds around 8.5-9.5 Mbps, but I'm getting 3 tops. And lately its diminishing to a few hundred Kbps. while the others are still up at full speed. Is there some setting on the router that is throttling down the wireless speed when using PPPoE? Thanks

Wireless connections are always slower than wired connections, but in most cases, you should be able to achieve at least 50% or more of the wired speed (unless you are so far away from the router that your signal is poor just from distance).
There are many causes for poor wireless connections, and many solutions:
First of all, give your network a unique SSID. Do not use "linksys". If you are using "linksys" you may be trying to connect to your neighbor's router. Also set "SSID Broadcast" to "enabled". This will help your computer find and lock on to your router's signal.
Poor wireless connections are often caused by radio interference from other 2.4 GHz devices. This includes wireless phones, wireless baby monitors, microwave ovens, wireless mice and keyboards, wireless speakers, and your neighbor's wireless network. In rare cases, Bluetooth devices can interfere. Even some 5+ GHz phones also use the 2.4 Ghz band. Unplug these devices, and see if that corrects your problem.
In your router, try a different channel. There are 11 channels in the 2.4 GHz band. Usually channel 1, 6, or 11 works best. Check out your neighbors, and see what channel they are using. Because the channels overlap one another, try to stay at least +5 or -5 channels from your strongest neighbors. For example, if you have a strong neighbor on channel 9, try any channel 1 through 4.
Also, try to locate the router about 4 to 6 feet above the floor, in an open area. Do not locate it behind your monitor or near other computer equipment or speakers. The antenna should be vertical.
Also, in the computer, go to your wireless software, and go to "Preferred Networks" (sometimes called "Profiles" ). There are probably a few networks listed. Delete any network named "linksys". Also delete any network that you do not recognize, or that you no longer use. If your current network is not listed, enter its info (SSID, encryption (if any), and key (if any) ). Then select your current network and make it your default network, and set it to automatic login. You may need to go to "settings" to do this, or you may need to right click on your network and select "Properties" or "settings".
If the above does not fix your problem, download and install the latest driver for your wireless card.
If your troubles persist, note that with newer routers, some users have found that WPA or WPA2 encryption works better than WEP.
If you still have trouble, for wireless g routers, try setting the "Transmission Rate" to 54 Mbps. For wireless n routers, try setting the "n Transmission Rate" to 162 Mbps, and the (wireless g) "Transmission Rate" to 54 Mbps.
Another option is to try to adjust the QOS (Quality of Service) options on your router. You might be able to give yourself a higher priority, and the wired connections a lower priority.
If you still have trouble, download and install the latest firmware for your router. After a firmware upgrade, you must reset the router to factory defaults, then setup the router again from scratch. If you saved a router configuration file, DO NOT use it.
Hope this helps.

WRT600N slow wireless speeds

I have a WRT600N router. I have one PC that is connected to the router via a wired connection. I also have an iPad (3rd generation) that is connected to the router via a wireless connection. On my PC, I went to speedtest.net and determined that I am receiving like 20MB downloads via the wired connection. However, my iPad only gets approximately less than 2 MB download speeds. I have tried reseting the router and I do have what I believe to be the latest firmware update (Firmware Version: 1.01.36 build 4). I also receive the slow download speeds when I try connecting the other wireless devices. I assume my problem has to do with some sort of configuration setting found in the router configuration page (http://192.168.1.1/). Can anyone please advise me what to do? The router is only a few feet away from my iPad so the signal strength is strong. I just don't understand why I'm receiving such slow wireless download speeds.
Solved!

This suggestion did not work. I tried to isolate the problem by optimizing the router's wireless settings. I used the 2.4GHz, set the radio band to standard 20Mhz then set the standard channel to 9. The laptop had the same slow wireless speeds as the iPad did.
This may be due to the IPv6 feature on your computer. One of the solutions may be disabling IPv6. If the issue still exist after performing this step and download speed is fine when connected straight to the modem then reset reconfigure could work, just use WPA2 for the security with AES and a fixed channel for wireless.

T410 slow wireless speeds

We recently acquired two refurbished T410's - both of these laptops have extremely slow wireless speeds (slow or no page loads) and it seems that they periodically disconnect from the wireless connection for short periods of time.
I have these laptops connected to the same wireless connection as many other computers in our office - all of the other computers operate normally - only experiencing this issue with the two T410's.
I see that others have had a similar problem, but have not been able to locate a solution. Any help the community can provide would be appreciated.
T410's running Windows 7 Pro 64

Very slow download speeds with ATT U-Verse

Hello,
Experiencing very slow download speeds with Macbook Pro 2011, on Lion, and ATT UVerse Max, which should allow for an avg. 11-12 MBPS speed. Instead, I get a fluctuating 60-370 kbps speed. I am not experiencing this problem on my Windows machines (Laptop running Windows 7 and Desktop on XP), it is only affecting the Macbook pro. I wonder if this issue is a known problem with ATT U-Verse and Macs, I spent hours yesterday with their support online and they couldn't help me, stating that from their side all settings were OK; the first representative from ATT re-booted the router remotely and that seemed to work for about 10 minutes, and then it went back to a crawling speed...
Any suggestions welcome!
Thanks

Do you have QOS enabled in your router? Did you try plugging the win7 laptop directly and check the speed?

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.

Help : very slow connection speed with AEBS and iMac

I connect to the internet using my newly purchased AEBS. I have a MacBook and an 24" iMac ( purchased in Nov 2007). My iMac showed very slow connecting speed of <1 MB/s download; with my MacBook placed just 1 foot from my iMac, the MacBook showed an amazing download speed of 20MB/s. If i connect the iMac to the AEBS using ethernet cable, it can get a very high speed.
So, where is the problem??
I am new to wireless, please help. I use iMac more than my MacBook at home.
Actually, i did not touch the any of the advance setting of the AEBS.

You know, I am experiencing the same problem. My wife's PC and iPhone are blazing fast, but my MacBook is accessing the internet at about dial-up speeds. Very frustrating and I haven't yet found the culprit.
Anyone???

EA6200 in Bridge Mode Slow Wireless Speeds

Hello All,
I just purchased a Linsys EA6200 AC router (refurb) to extend my existing wireless network. I have setup the 6200 as an access point using the Bridge Mode outlined in the Users Guide (automatic configuration). While I am able to connect to the Internet from the router wirelessly, my Internet speeds while connected are roughly a third of my max MBPS, I have a 55 MBPS connection and consistently get speeds around 14-20 MBPS with this router from a 10-12 foot wireless distance. I get full speed while wired in, however, as soon as I go back to WiFI I get a significant performance drop.
Is there something that can be done to correct this? I am running the latest firmware and have set the 2.4G channel to 20mhz and the 5G channel to 40mhz while specifying a channel number with no increase in performance or speed. Any help would be greatly appreciated. Thank you.

What Mfr and model is the main host router?
Try single mode G or N or mixed G and N on 2.4Ghz and single mode N or Mixed on 5Ghz on the main host router?
Channel Width set for Auto 20/40Mhz. 20Mhz can slow the wireless speeds down.
Try setting a manual Channel to a open or unused channel. 1, 6 or 11. 11 for single mode N if the channel is clear. 13 for EU regions. Try channel 48 or 149 on 5Ghz.

Very slow download speed with intermittent halts

Need some help.
I run Apple os/x latest version and have since yesterday begun to experience constant very slow download speeds.
I have rebooted the router and I have reset it. I have tested with wireless and wired into router. No real change.
The results are below and are pretty consistent no matter when or with what computer I test it with.
This is very frustrating and I would like to know if anyone has experienced this and if there is anything I can do before calling for service.
Thank you in advance.

Wrt54gs2 slow wireless speed

I have a brand new wrt54gs2. At first I had trouble getting to the configuration page unless I rebooted it. I upgraded the firmware and seemd to fix it, but now the wireless speed is very slow. I configured it as I have configured many 54gs before. The wireless speed is less than 1MB and the wired speed is over 12MB. Any suggestions. (I want my wrt54g back!)

@sandman879 Thanks for the pointer!!
I registered with this site just to respond!
The wireless web access check was exacttly it!
I did the firmware upgrade to the June 2009 release, and I was still slower than 4k upload and 87k download. After I did the check on the web access from wireless, I was back up and running at normal speeds.
I like the idea of locking out the router maintanace page to wireless users, but not at the expense of killing off bandwidth.
I really hope Linksys/Cisco takes a look into that and upgrades the filter on that. I wonder if the router just got overloaded with inspecting the wireless packets for destination addresses of the router. LAME! That's a 1993 problem.
So really everyone, check to see if you have the Wireless Web Access option disabled, then take a deep breath and tell that security monkey in your head to shut up and enable that option.

Slow wireless printing with Airport Express

I have a Canon MP530 printer hooked up to an Airport Express for wireless printing. My wireless internet network is through an Airport Extreme. The only thing hooked into the Express is the printer, and it works but is extremely slow. It can take an hour to print one 15 page document. Any ideas how to fix this?

I'm not sure I understand your question, or at least I don't know how to tell connection speed with the utility. The express is set up as an extension to my current wireless network, although I'm only using it for printing.
I had a similar experience with a hard drive wirelessly connected to the Extreme - data transfer was ridiculously slow. Is this something to be expected with wireless connectivity?

No, BT does not have one, only web forms.
This forum should be able to help if you would like to specify which BT Home hub you have, and what wireless devices you are having problems with. Also, are you on ADSL or a BT Infinity connection.
Is your speed fine, if you use an Ethernet connection?
BT do not guarantee wireless speeds, as there are too many variables.

VERY slow wireless speeds since Infinity 2 upgrade

I don't know whether it is just coincidence or not but ever since BT upgraded my Infinity Unlimited to Infinity 2, the wireless speeds on my home network have been ridiculously slow. With a wired connection I get about 55-65 Mbps download and 10-15Mbps upload typically, while on wireless it's a fraction of that. For instance, the last test I did gave 3.33Mbps download and 0.13Mbps upload! I have tried different routers, tried changing the wireless channels, tried turning off other wireless equipment in the house, all to no avail. The strange thing is, the wireless signal strength is showing good to excellent. The speeds I obtained when Infinity was first installed were typically around 20Mbps download and 7-8Mbps upload.
I have contacted BT India and they said they were going to run some tests today, but I can't imagine how they are going to diagnose this problem remotely. Has anyone any ideas about what could be causing this and how I can go about finding a solution?
Solved!
Go to Solution.

I am rather hoping that an engineer will be able to confirm whether or not the wireless signal is being degraded by interference and if so, what might be the cause and/or the general direction it is coming from. I have carried out all the tests I can do on my own, such as changing channels, routers, etc and turning off any other electronic devices in my home that emit radio signals, but nothing has made a jot of difference. All I know is that until a couple of months or so I had a great wireless signal, but now I do not. I can't find the cause without the help of an expert (i.e., BT engineer) coming to check what is going on. If BT are only interested in providing a good signal by ethernet cable, then they shouldn't be adverting on the TV how great their HH3 is at distributing a wireless signal around the home if it only works like that some of the time or for some people.

Very slow wireless speed

The wireless speed on my 15" MBP is abysmally slow! I restarted the laptop, installed the new firmware patch, and restarted my router, but nothing seems to work. I am actually making this post from my Windows Laptop, which is connected to the same wireless network and does not have any problems.
Does anyone else have this problem? Any suggestions on how this can be fixed?

Yes, many, many people have these same problems. These URLs were posted on another thread almost a month ago...If you look closely through the dozens of threads, hundreds of posts and thousands of views, you will realize that you are not alone...and, it has nothing to do with your router or your security settings - it is simply your MacBook Pro. We've been 'suffering' with this problem for months now and our 'glorious' Apple has yet to acknowledge that there is even a problem. Apparently, it takes the NYC school system to put a hold on Apple orders to get a fix for this...to h__ with the thousands of single user MBP customers. After 28 years as a dedicated Apple user, I've decided not to buy the Air (even though I liked it and it doesn't have any issues). I'm in Paris using my daughter's Intel MacBook (which has its own problems - like waking up from a sleep) having left my MBP on shelf because it can't can't maintain a steady, decent wi-fi connection. I would have thought that the release of 10.5.3 would be released by now but no such luck.
