Slow wireless connection since OSX 10.4.8 update

I have a Powerbook (non-Intel) and a Netgear connection. Since the 10.4.8 update, my Internet connection is horribly slow or pages never load or Safari/Firefox says 'not connected to the Internet' even though I've got a full signal and I'm sitting directly in front of the modem. Another computer in the house (non-Mac) has no issues with Internet. I've made no other changes to my laptop, period, so it has to be the update.
I already searched the Discussions board for a fix and found nothing. Anyone have any suggestions? Should I reinstall an older version of 10.4 that worked just fine? I telecommute for work and need fast access so this can't go on.
Mucho thanks for any advice that anyone can give me, Kat

Hi Kat,
I've read several, (hundreds?), of these complaints, trouble is there are many different reasons... I'll name a few to start us off...
Using Delta Updates rather than Combo updates.
Certain Broadcom Chipset based Modems/Routers might work fine for months, but then won't with Macs. Many varied symptoms including yours.
Trashing these files and rebooting and setting up Network Prefs again...
/Library/Preferences/com.apple.sharing.firewall.plist
/Users/nnnnLibrary/Preferences/com.apple.internetconnect.plist
/Library/Preferences/SystemConfiguration/preferences.plist
/Library/Preferences/SystemConfiguration/NetworkInterfaces.plist
Geez, there's too many to name off, but...
At this point I think you should get Applejack...
http://www.versiontracker.com/dyn/moreinfo/macosx/19596
After installing, boot holding down CMD+s, then when the prompt shows, type in...
applejack AUTO
Then let it do all 5 of it's things.
If it doesn't fix the problem

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...

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.

Ever since I received my Macbook Pro in July 2011 I've had issues with my wireless connection at home. After software updates, Apple support suggested I reboot my router which works. But now I have to do it every other day. ????

Ever since I received my Macbook Pro in July 2011 I've had issues with my wireless connection at home. After software updates, Apple support suggested I reboot my router which works. But now I have to do it every other day. ???? AT&T my DSL carrier suggests I get a new router. Apparently the one I have is really old and doesn't support my Macbook Pro. Does this sound right?

If your using WEP encryption yes, Apple has discontinued that becaues it's worthless. WEP (and WPA) is cracked so encryption makes no sense.
Get a new Wireless N router, set it up with WPA2 (AES) Personal and two different 20+ randon letter/numbersymbol character passwords
One for Admin access only of the router, keep this on paper off all comptuers in a safe someplace.
One for entering into devices, computers etc for Internet Access Only.
You need the long and random password to defeat brute force attacks by GPU software that the hackers have now.
Also if you give out the password to another, they can't hack the network with the guest access password.
Computers remember the internet password, so anyone with access to your machines or network will have the password.
Since you have another Admin only password, they can't hack in. got it?
You don't need "Invisible" or "MAC Address filtering" that's a waste of time as hackers can sniff a network and causes issues getting on the network.
Good luck.

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.

Why is my iPad so slow or freezing since the iOS 8.02 update?

Why is my iPad so slow or freezing since the iOS 8.02 update?

Do a reset, no data loss. Hold down the home/sleep button together until you see the apple logo and then release, then wait for the ipad to boot back up.
If that doesn't help - settings - general - reset - reset network settings - no data loss, however you will need to reenter known wifi passwords.

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.

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.

Slow Wireless Connection (WRT54G2)

Hi, my WRT54G2 router has been working great since I got it a year ago. But recently I'm experiencing really slow wireless speed. My normal speed is around 15 Mbps but now it has dropped to about 0.85 - 1.0 Mbps. At first I thought someone might be using my connection without my knowledge so I changed the password but it was still slow. I then changed my wireless channel (I heard that if too many people are on the same channel it can cause interference) and it worked. However, a little bit later (sometimes a few hours and sometimes a few days) my connection would become slow again. I have also tried upgrading my firmware but that didn't help much either. Does anyone know what can cause a problem like this? Any insights are greatly appreciated. Thanks.

Do the following steps: # Open up the browser and on the address bar type 192.168.1.1 that will open up the Router setup page.# Lower the MTU (Maximum Transmission Unit) from 1500 to 1400 or less (usually found on your routers main/ basic setup page)# Then go to the Wireless tab, keep network mode as mixed, make the Channel Width to 20 MHz only and Channel to 6, 9, 11.. #Adjust the following advanced wireless settings:~~ Lower the beacon interval from 100 to 75~~ Lower the fragmentation threshold from 2346 to 2306~~ Lower the RTS threshold from 2347 to 2304 Then check the wireless status..

Slow Wireless Internet Since 10.5.5 Update

Hi.
When I click any link or enter any URL in Firefox, the status indicates "Looking up (URL)..." for literally 5-10 seconds before loading the web page. This happens on all browsers (including Safari, FireFox 3, Camino, and Opera) and has started since the 10.5.5 update. I've tried it on my college's network and it does the same thing. Running Windows via Boot Camp does not suffer the same problem. I have many other computers and devices on the same network that do not experience this problem, thereby eliminating anything other than the Mac OS at fault.
What the heck did 10.5.5 do? Is there a fix for this other than running a restore with Time Machine and going back to 10.5.4 (which IMO is super stable and problem-free)?

Weird problem here too. I've had wireless problems of all kinds since Leopard. Then with 10.5.3, 10.5.4 things settled and worked fine. Now this!! Ahhhhh! I have full wireless signal, email is slow but works. But browsing is very slow. Funny thing: not to every site. There are some I used to visit which are now almost unreachable; they start to load, then they fall asleep with the browser saying "connecting to...". Once every 10 or 20 refreshes then succeeds in loading the page. But clicking the next link from there the problem is back. Definitely after 10.5.5. No other changes of any kind. Not a DNS problem, at least not directly: nslookup looks good, tracing routes is ok also (14 hops away). Connection to other machines in the lan ok. Connections from ethernet linked machines (and also from the iphone) to the internet no problem.
I'm looking for a way to go back to 10.5.4!!
P.S. By now I'm almost sure this is a hardware issue, some sort of incompatibility at a hardware level, which apple is aware of (but can obviously not admit) and at some time decided to patch somehow - using some sort of software hack...but then forgets about it at the following update, so here we go.

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 ...

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 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.

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?

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.
