T61 and slow wireless connection

I have a T61, type 6457-E3G using Vista Business.
I have a problem when I try to connect with my ZyXEL router, it's a P-2602HW-D1A. I get the same download speed as I get when using LAN, but my upload speed behaves very strangely. It starts shoving a medium speed, but instead of going up to max. speed, it slowly slows down till there's almost no connection.
Recently I changed my hard disc. (WD Scorpio Black 320 GB/7200 RPM)
I used to have the same problem earlier, with my old HDD, but suddenly, one day, it was just gone and the upload speed via wireless was almost the same as LAN.
I remember I updated all the drivers (Lenovo and ZyXEL) on the old HDD and thought that was it, but unfortunately it wasn't...
I have no problem connecting to my D-Link router and I use Access Connection.
Any advice would be very much appreciated
All the best Ebbe

Thanks for taking the time to answer...
I'm using Vista Business and it's not only a problem with streaming media being slow, it's all my downloads, including my mail. After a short while the connection slows down to almost nothing... and I have a 10 Mbit/1Mbit connection...
The strange thing is that our T43, running XP, has absolutely no problem with the WLAN connection and also, as I mentioned earlier, that this T61 used to function properly before changing the HDD... well, in the beginning it didn't, but suddenly one day it did, unfortunately I don't know what actually made the difference... so being no expert, I imagine it could be some kind of a missing driver, but if so... which one... ?

Macbook and slow wireless connection

I have trouble reaching high speed when connecting with AirPort to my BT Voyager 2110 router. Connecting with a cable works great.
It seems to be a problem many people have that their wireless connection between the Mac and a router gives only a fraction of the transfer speed compared to when when using a PC and connecting wireless to the very same router. Is Mac more sensitive and have compatibility problems?

I solved the problem I described above. I changed the channel on the router to 11. Tech support told me that Macbook prefers 11, then 2 and then 6. I tried number 2 yesterday and it was still bad. However, channel 11 solved my problems. Now the wireless is fast as with cable.

One Solution for Fixing Slow Wireless Connection

Quick and easy solution for slow wireless connection.
My hardwired PC connection was working fine over FIOS, but my wireless connection through my Macbook Pro was soooo slowwww, although the machine itself was fine. Pages would take forever to appear, then finally sort of pop up. Didn't really seem to be a Mac problem, just a connection problem.
After searching forever to find a fix, I found a quick & easy solution that works at least for now: change your DNS address.
I'm not a techie so I don't know ALL of the implications of doing this, but in desperation, it has worked for me and I think at no risk to your network or machine. Changing my DNS address has made my connection blazing fast and relieved many weeks of frustration.
HOW: I can only share how to change on a Mac. (Please chime in if you can give directions for PC. ) Just go to this Apple support page, which will outline exactly how to do it. I used 4.2.2.2, I think you can also use 4.2.2.1 as the DNS address. http://support.apple.com/kb/TS2002
Other resources I've found follow:

Maybe this is a commonly-known fix but it wasn't for me, so hopefully it will help some of the other less-than-technical people out there. Good luck!

Actually this is a common problem with Mac OSX (http://rubyisbeautiful.com/2008/2/8/osx-dns-fix-update) and how it does DNS lookups and pertains to routers that provide the internal gateway (i.e. 192.168.1.1) as the DNS address which is what the ActionTec does by default.
You can change that at the router level to either push out Verizon's dns that the router then uses or any other open dns server. I had to do this a long time ago for some of the OS X boxes on my network.

Snow Leopard freezing and slow wireless

I installed Snow leopard, installation went fine since then my computer will randomly freeze for increments of 30 seconds up to a few minutes. Happens on iTunes, Quicktime and safari. I also find to have a very slow wireless connection since the installation. Any ideas?

strange, my wifi's as fast as it normally was.
machine is: macbook 13.3" unibody 2ghz, 4gb ram
wiped it clean beforehand, installed SL fresh then restored my work via time-machine on install
Cocktail's a good util to customize your wifi speed, although it won't work on SL
My machine is set to 64bit mode though, however to be honest the 32/64 bit is a mystery at the moment, seems the kernel remains at 32 whereas the rest can happily go to 64bit with 64bit apps running happily against 32bit ones.
May want to time-machine your work, install fresh and restore from time machine. just use a usb-portable or huge memory stick, will only need to do it once.
Michelle's machine has the same problem (core duo macbook white), going to look at that tomorrow, will post if i solve it

I have a MacBook Air, which I just upgraded to OSX Lion. I also have the latest version of iTunes. When I try to stream to the AirPort, the Airport resets, and the wireless connection on the macbook locks up. Any suggestions where to start?

To free up hard drive space the best bet is to move data files that you don't need access to all the time. Likely candidates are music, video, and photos. Things like word processing and spreadsheet files can also be moved but they tend not to be very large and so don't free up much space. The problem with moving the above mentioned files is that iTunes and iPhoto need to know where the files are stored.
Here's an article explaining how to move the iTunes folder. You can move the iPhoto library using the Finder but there is a slight complication. Start iPhoto, open the Preferences and click on the Advanced tab. The first option is "Copy items to the iPhoto Library". If this option is checked, copy the iPhoto library to your external folder (drag it from the Pictures folder to your external drive) and then delete it from your Picture folder. If this option is not checked, it is a bit more complicated and we'll need to talk a bit.

Linksys E2500 and Mavericks wireless connection

Installed Mavericks and lost wireless connection with my linksys e2500.
Cisco connect says "unsupported operating system" and "visit http://homesupport.cisco.com/linksys/support"
Cisco website does not address Mavericks OS

I'm having the same issue with my Cisco Linksys router.
I am unable to connect to the wifi network, or use the Cisco Connect application. As the application is the only way of adding and removing devices from the network, changing the password, and likely fixing this issue, I'm quite frustrated.
I phoned Cisco about this issue yesterday and they had no helpful information. They advised me to download the newest Connect software from their website, and stated this should fix the issue. I told them that I'd already attempted this solution, but their software has only been updated to include a compatibility fix with 10.8, and the issue is with 10.9. They then advised that I restart my computer. AKA, they would be no further help.
The Connect software is available for download here, so I hope that they release an update soon with a fix to this problem. The release notes under the latest update include a mention of the 10.8 compatibility fix, so I hope a 10.9 fix will be forthcoming.
The only solution in the meantime seems to be a complete restart and install of the router and software using a PC. And even this only works to correct the Cisco Connect issue, and likely not the main issue of actually using the wifi network with Mavericks. Regardless, I believe this is a Cisco/Linksys issue, and not an Apple issue.

Slow wireless connection 802.11n AEBS and Intel Core 2 Duo MacBook Pro

I have three Macs all currently connected wirelessly to the new 802.11n AEBS.
Mac #1 - PowerMac G5
Mac #2 - 17" MacBook Pro Intel Core Duo
Mac #3 - 15" MacBook Pro Intel Core 2 Duo
The wireless connection speed (when using the web browser) is fine for both Mac #1 and Mac #2 but noticable slower for Mac #3. All three Macs are sitting right next to each other. All three Mac are getting an excellent signal. All three Macs are running the same version of the OS. All three Macs have identical network setting (as far as I can tell).
When connecting Mac #3 to the AEBS via an ethernet cable, performance is good. I've also tried configuring the channel manually in the AEBS to channel #1 but this did not help (seemed to help others in a different thread). Additionally, I ran the 802.11n enabler and performance was bad both before and after its installation.
Any idea why the Intel Core 2 Duo MacBook Pro would be performing differently?

Ok eveyone. I did some digging and was able to get the network speed back with my Core2Duo machine. I put the Airport Extreme into Bridged mode and connected the Ethernet cable to one of the LAN ports, not the WAN port. After that everything works great. for more information check out this lengthy thread...
http://discussions.apple.com/thread.jspa?messageID=3989864&#3989864
and this site mentioned...

Apparently the new base stations have a few issues that need to be worked out so I'd consider this a workaround. There should be no reason to have to do this. Good luck.

Orange Livebox & MacBook Pro Slow wireless connection

Hello,
Looks like we are a lot experiencing a slow or sporadic wireless connection.
I have done all updates, the MBP finds the livebox and connect properly but I have a very slow connection.
Lan connection is working fine and quick.
Please could somebody help me, this is my first Mac, if there is any tips or tricks to get a normal wireless speed.
Cheers.

What kind of wireless router or access point are you using?
Are you getting full signal?
Is the wireless router or access point around anything with a lot of metal or..
since you said that when you connect to your modem via ethernet then you could have a problem with your wireless infrastructure... if you have tested your wireless network with another computer and it works fine or if you went somewhere that has a hot spot then you can determine if there is an issue with your home network or an issue with the wireless card in the laptop...

Very Slow Wireless Connection

I bought a while ago a WRT54G V6.0 and although the wired connection works pretty well, the wireless connection is very slow, I have trouble accessing web pages but once it enters a site i can navigate through it without a problem, but when I go to another website I struggle to enter. I have tried updating the router several times, changing the transmission channel and it seems nothing works. could someone please help?

try changing the MTU size on the router ui in the following order .... 1492 , 1452 , 1365 ... check whether it makes any difference ...

Slow Wireless Connection

I am having problems with a very slow internet connection, that seems to be getting slower.
Currently we have a DSL Modem connected to a LinkSys DSL Router connected to an Airport Extreme. We have been using this setup for several years.
We run 2-4 laptops of various types...MacBook, MacBook Pro, and 1 Windows. Today, I can hardly get my MacBook to go anywhere.
I went up to my iMac G5 and plugged in the ethernet directly to a port in the router and did a DSL speed test through my ISP and it came back as 4.4 Mbps, about the same as it has since I upgraded speeds last fall.
I then disconnected the ethernet and switched back to wireless, and ran the same test. This time is came back 775 Kbps.
Any suggestions? Thanks!

I am assuming that you are still having the issue with network performance, or at least it has not stabilized.
I would still think Wi-Fi interference to be the potential issue and suggest that you pursue this a bit farther ... if you don't mind.
Again, I would suggest downloading a copy of iStumbler. Use iStumbler's Inspector feature (select Edit > Inspector from iStumbler's menu) to determine the Signal-to-Noise Ratio (SNR) at different points around your house, by performing a simple RF site survey. Within the Inspector, note the values for "signal" & "noise" at these locations. Start with your MacBook near the base station, note the readings, and then, choose the locations where you will typically use your MacBook to access the Internet.
SNR is the signal level (in dBm) minus the noise level (in dBm). For example, a signal level of -53dBm measured near an access point and typical noise level of -90dBm yields a SNR of 37dB, a healthy value for wireless LANs.
The SNR, as measured from the MacBook, should decrease as the range to the base station increases because of applicable free space loss. Also an increase in RF interference from microwave ovens and cordless phones, which increases the noise level, also decreases SNR.
SNR Guideline
o 40dB+ SNR = Excellent signal
o 25dB to 40dB SNR = Very good signal
o 15dB to 25dB SNR = Low signal
o 10dB to 15dB SNR = Very low signal
o 5dB to 10dB SNR = No signal
If the SNR is 20dB+ at each of these locations, then you should be getting reasonable performance from your AirPort. If less, either try to locate the source of the Wi-Fi interference or try relocating either the base station or the wireless clients until they are within a 20dB SNR range.

Has anybody solved the slow wireless connections speeds of the new Imacs

I have just purchased the new imac...and was made aware of the disastrous connections speeds using wireless.. Does anybody know if apple have come up with a solution...or are they just not dealing with the problem?

I am a brand new Mac user with a new 24 inch iMac purchase. Macs are supposed to be hassle free right? Right. No question I was about ready to throw it out the window because the wireless connection to the expensive AP base station was, oh, 100x slower than my Dell laptop side by side about 1 foot away. Nothing changed even if I connected directly to the AP using an ethernet cable. My connection consists of an Actiontec DSL gateway connected directly to my AP extreme that allows wireless to my PC laptop as well as my new iMac. Hours and hours go by until I find this help link on Mac Orchard Forums:

Slow wireless connection after 10.4.11 update

Hi,
I have a 17-inch iMac (2Ghz cpu) and ever since I updated to 10.4.11 my wireless connection has been very slow. I used to have download speeds between 150 and 200 KB, and now I can’t get past 20 or 30 KB. I have an XP laptop right beside the iMac, using the same wireless router and the connection is a lot faster, achieving the 200 KB I used to have with the iMac.
I also used to transfer files a lot faster than I do now. I connect to a pc through smb and transferring files is really, really slow. It takes ages just to begin the transfer, and a 5MB file can take up to 15 minutes. It never took this long…
The connection is quite stable though, it rarely disconnects, so I’m not sure whether I’m having the same problem other users have been posting in the forums. What I do know is that the update messed with my wireless connection.
I’ve tried running Disk Utility’s repair disk permissions, Applejack’s AUTO repair, trashing plist files that I saw in other posts, nothing works.
Anyone with the same problem? Any ideas?
Thanks,
josemagalhaes

Hi again,
I think I found a solution for this. It’s not the best solution, more of a workaround, but it’s been working for me.
Searching other threads, I found this topic about users who had intermittent connection to the internet (http://discussions.apple.com/thread.jspa?threadID=1027382&tstart=0). I tried changing the settings in my wireless router – not Linksys, it’s an Asus WL-520G, but has similar options – and the speeds were up again! SMB file transfers work at good speed, and the internet connection is back to normal.
I’m not sure what these settings are for, but anyway all I did was change the “Beacon Interval” to 50, “RTS” to 2304 and “Fragmentation” to 2305 (I didn’t change the MTU because that seemed to be a PPPoE setting, not wireless).
As I said, it’s not really a fix, because nothing changes in OS X, but anyway it may help some users who’ve been having the same problem.

MacBook Pro 2010: very slow wireless connection

I know a number of people have posted similar questions, but I think I've done everything I can to fix this.
I bought a 13 inch MacBook Pro last week, and found I was getting a very slow connection to my wireless network. OK when I was right next to the base station, but very slow in another room (the room I want to use it in).
I checked with speedtest.net, which showed I was getting download speeds of around 0.3 Mbps - although, curiously, it showed upload speeds of 1.5 Mbps. I ran my old MacBook in the same room, on the same wireless connection, and consistently got speeds of over 10 Mbps. So it can't be the network that's causing the issue.
After an hour on the phone with tech support, I took the Mac back to the Apple Store, where I was unable to get any wireless connection whatever. They exchanged it for a new machine. Worked fine in the store - but when I got it home, I was still getting very slow speeds. The old MacBook still outperforms it by at least a factor of ten. All the system software is up to date.
Is this a dodgy batch? Or has the wireless range dropped considerably with the new MacBooks?

Darin,
You're right - there are a lot of issues about MBP WiFi. I think there's a major problem with it.
If there was a ..."major problem with it" you would see more complaints than wifi just being among the top 10 discussion items in a trouble shooting forum. There are millions of MBP users many of whom, like myself, use wifi every day without issue.
Your statement "They exchanged it for a new machine. Worked fine in the store - but when I got it home, I was still getting very slow speeds." would lead one to suspect maybe interference from some source or a configuration issue rather than a "major problem".
You probably already tried changing the channel, resetting your router, changing the security scheme, elimination possible sources of interference, separating your components (router, computer, external monitor, ...), etc. but maybe starting over with a default configuration will help isolate the problem.

Terribly slow wireless connection.

hi, I have a wireless B router model BEFW11S4 ver. 4. My wireless connection says that it is usually "good" or "very good", but when browsing the web i get painfully slow speeds. When i reset the router and go into the settings and restore my network settings my connection speeds are fast again for about 10-20 minutes before it is painfully slow again. This is terribly frustrating. can anyone please help me, i would appreciate it! thanks, mike

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.
Some users have reported improved wireless performance by switching from WEP to WPA encryption.
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.

Not sure if you performed this or not, once you do a factory reset, immediately after that you are suppose to perform a factory reset by holding is the reset button in on the back of the linksys router for 30 seconds, then wait about 2-3 minutes for the router to sync back up.
Important = Write down your previous settings in the router as they will be erased and you will have to manually input the info.
Hope that this will help,
Ttech
If not, try this
Here are some steps to follow for a slow or poor connection.
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
