THis Wireless Issue is a Head Scratcher

As some know, I bought 2 Macbooks in Dec '06 and was experiencing all sorts of wireless issues early on. Dropped connections, SLOW transfer speeds while networked to my Imac, etc.
At some point Netgear released new firmware for the 824, and all seemed right in the wireless world for at least 2 months.
No issues with OS updates or airport updates, it seemed.
Al of a sudden last week, I went back to the extremely slow speed when networked from the macbook (wireless) to the iMac G4 800 (wired) and nothing so far will fix it.
The wireless transfer happens in 500K packets and a 4 meg file takes 4 minutes to transfer. Yet if I plug in the ethernet cable to the macbook - it works as it should.
What I can't figure out is what happened to make this annoying issue return out of the blue.
I am also back to slow page loads via Safari and page hangs.
Of course I have rebooted the router -
I can't figure out why for at least 2 months everything worked perfectly after months of sub par wireless performance and then back to **** - with everything back to sub par except not dropping connection anymore.
Thoughts?

I think the first thing I'd check for is if some source of interference returned after a few months of absence. I have a 2.4 GHz cordless phone that will nuke my 2.4 GHz WiFi connections - but only sometimes - when the phone happens to pick a channel that coincides with my WiFi. It could well be that a phone in your neighbor's house gets on your channel, and if the the phone doesn't experience any trouble may sit on your WiFi channel for a long time. In my case, my Panasonic phone bothers the WiFi, but the WiFi never bothers the phone.
The other thing you might want to look for is how many IP packets are being discarded by your Mac's network interface. You can do that my opening a terminal window and doing "netstat -s | more" The -s option gets you a rather extensive list of Ethernet statistics. What you want to look for is anything related to retransmitted packets. If you are experiencing more than a 1% IP packet loss, Ethernet performance can degrade rather ungracefully. (Note, I'm talking about layer 3 and above IP packets). It isn't unusual for 15-20% frame loss at layer 2 in the WiFi connecdtion.
There are a lot of variables here, and it is difficult to give you an answer that would be a one-step magic pill. There could be several problems at once. The best test would be: does one computer have lousy web page load times over WiFi, but the other computer has quick web access.
If both computers are having problems loading web pages, then there is something wrong with the router and/or WiFi interference. If just one computer has poor performance, then you need to look at the software on that computer.
Best wishes for finding it.

  • How can i fix this wireless issue?

    My problem is, few days now my wireless router either not showing my SSID or give me Worst signal even though im far from it like 5ft.,it sometime load fast then right back slow.
    but when i run a speed test on verizon website i get a decent
    21Mbps download  and 15mbps upload
    and this happen to almost all my devices, tivo, iphone, xbox360 and laptop.
    how can i fix this problem.
    this is the first issue that i have with this router.

    change the wireless signal.  you can do that in the router.   open a browser, and go to http://192.168.1.1
    user name is admin.  and the password is most likely the serial number found on the service tag of your VZ router unless you changed it.
    }Once you login succesfully, go to the top and hit wireless, then on the left basic security.   then go to option 3 which is channel
    1, 6 and 11 and are the only channels you should try.
    So it will likely be set to auto, change it to 11 and put the check for keep settings even after reboot (Directly under the channel) and then hit apply.,
    after you hit apply,  test your connection out, if you notice a difference, leave it like that until the problem happens again, and if it happens again, go back into the router, and try channel 6,     test it out.  and then finally 1 if the first two don't work.
    Also take a look at page 2 of Actiontec's Wireless PDF File.  It gives you some idea's with regards to position and orientation of where the router sits and how it can best be positioned for maximum coverage.

  • Macbook airport wireless issue

    Hello,
    I have a macbook from around 2006/2007, and up until last year has been very reliable and something that is still quite speedy.
    I have an issue with the airport/wireless on the mac, whereby the signal is so intermitnent and sometimes non-existent. My internet (virgin internet super hub) works perfectly with all my other devices (iphones, ipads etc) so it's just this one device.
    When I start the mac up, first of all it stats that the connection times out and unable to connect. It also wont connect when I'm around 10 feet away or further so I have to sit quite close to the router.
    After around 5 minutes the signal builds gradually in strength, and gets to 1 bar, then jumps up and down from full (4 bars) to 1 bar whilst connected, never stable - this allows me to connect (just about).
    I have just done a test with my iPhone and set my iphone perso
    I am running Mac OS X 10.5.8 and have done all the updates for airport and software.
    Right now whilst I'm writing this message the wireless strength has dropped from 3 bars and I'm now on the lowest bar.
    I have had a few people look at this and the airport card (to my knowledge) has been replaced yet we still have this issue.
    I also have an issue where if I unplug the power the computer instantly dies so I presume the battery is dead and needs replacing, however it works fine as long as it's plugged in. The main issue is this wireless issue which would be amazing to fix and get this old beast working perfectly again.
    Any thoughts on what we can do? As stated, the internet works perfectly for all other devices and we've switched since and still have the same problem so I;m 99.9% sure it's the computer.
    Many thanks for your help and look forwawrd to some feedback
    James

    Update:
    I have since added a new user to the account and the problem still persists on the other user account.
    I have also ran a 'network diagnostic' however because the internet kept dropping, it either stated that there was no problem or it wouldnt run at all. I have installed iStumbler and it shows signal strength ranging between 24% - 32% and the graph shows it is dropping out quite frequently.
    I have seen people recommending i switch from channel 11 to channel 6, but not sure it will be this simple as we have changed routers and internet numerous times...
    Any thoughts?

  • This is a workaround for the MBP wireless issue

    There have been many topics on the MBP wireless issues already, but I thought some people might find this workaround helpful.
    Firstly, my system is a 2.2Ghz MBP, running 10.4.10, and also airport extreme update 2007-04. I am using an airport express base station. My previous Powerbook never had any wireless problems, so I really couldn't blame the basestation for the MBPs poor wireless.
    Warning - The workaround requires a little bit of work in the terminal. A little bit of understanding of how networks work is assumed here as well. So it is probably not for everyone ...
    What I have observed - whenever the MBP loses connection, the airport basestation IP and MAC addresses are missing from the ARP table.
    - To view the ARP table, type (in a terminal window) arp -a.
    So, when the MBP wireless hangs, open up the terminal and type that in.
    Do a Cntrl-C if the arp command is hanging and not returning anything.
    In normal situations, a list of IP addresses and MAC addresses will show up.
    As others have already noted, clicking on the airport icon in the menubar, will magically bring the wireless back to life. When this happens, the ARP table also gets magically populated correctly. Coincidence? I think not!
    So, the workaround is to store a PERMANENT entry in the ARP table for the airport basestation IP and MAC address. In my case, I can use the Airport Utility software to confirm what the basestation IP and MAC addresses are (note MAC address = Airport ID in Airport Utility). I found the basestation IP=10.0.1.1 and the MAC=0:11:24:07:d7:f
    To create a permanent ARP table entry for my airport basestation, I opened up a terminal window, and did the following -
    1) login to my administrator account
    2) type in the following command sudo arp -s 10.0.1.1 0:11:24:7:d7:f
    3) type in my administrator password to authorise the change
    4) type in (to confirm the changes have been made) arp -a
    5) logout of my administrator account (from the terminal)
    Ever since I did this, my MBP wireless performance has been flawless.
    Note, if you shutdown or restart your computer, the arp entry disappears. This is ok for me as I hardly ever power down my MBP. As insurance I have added an account startup item to remind me to do the arp table entry.
    This workaround is great for me because I don't have a need to use multiple wireless networks. It might not be practical for people who roam around onto different networks.
    Give it a go and see if it works for you.

    OK, after some further experimenting, I changed the multicast rate on my airport express. It was set at 6Mbps, and I changed it to 2Mbps.
    I have read that the default multicast rate for previous 802.11g versions of Airport basestations is actually 2mbps. Excellent results so far !! I have set up a terminal command to continuously ping my airport router address every 15 sec, and there have been virtually no dropped packets so far over many hours.
    ping -i 15 10.0.1.1
    Interestingly, in Apple's Airport Admin software in my MBP there is no option to set the rate at less than 6Mbps (!!!!), so I had to use the Windows XP version of Airport admin software to make this change using a windows machine. Using the XP software you can set the muticast rate as low as 1Mbps.
    If you are using Apples airport admin software (Tiger and Leopard) and you commit any sort of change in settings, the multicast rate will be re-set at a minimum of 6Mbps. My understanding of the multicast rate is that setting it too high is similar to shrinking the coverage area of the basestation, and limiting access only to clients who can transmit at the required multicast rate.
    So my new theory is that the dropouts are caused by the MBP dropping off the airport due to not being able to achieve the set multicast rate. (this could be due to factors such as low signal strength, excessive interference or noise).
    If you are using Apples more recent Airport admin software, you are having a minimum 6mbps muticast rate set, and this might be too high for your particular environment.
    Just a theory.
    (oh yeah, I enabled interference robustness on the MBP and the basestation just for good measure)

  • Is this a dropping connection or a wireless issue....

    Hi all,
    We've been having some problems with our Infinity setup for a few months now and it's getting a bit annoying, I could use some help in fixing it
    So, every evening (could be daytime too, we dont use it then really) our connection seems to drop every 10 mins or so. If I'm gaming, it will drop me out of a game and I'll have to reconnect. I can usually reconnect in seconds. If we're watching Netfilx, it will stop, and restart a few minutes later...
    Oddly, the blue Hub lights (HH3 I believe) never falter, solid blue throughout.
    Restarting the router (and white box thingy) works pretty much everytime - and only occasionally are we disconnected for more than a few minutes.
    The setup is Infinity 2 I think, into the master socket. I'm running a handful of Apple devices, a home server, a Mac and a PS3. Probably important that none of these devices have changed at all location, spec or otherwise.
    Occasionally my server cannot be found on the network either, despite it running continuously - a restart usually cures this but would it point to a dodgy router? (it's a wired connection,so no wireless issue)
    I'm guessing I need to run some tests but not sure what?
    I did try and call BT Support a while ago, but the chap said he couldn't help me because my Mac Air has no ethernet cable, just wireless

    seems to me like a faulty router or modem mate, to make sure its not actually dropping fully you will want to login to the router page using 192.168.1.254 then going to troubleshooting and then helpdesk and it will tell you the uptime. login with the password which should be on the back of your router. do this when the wireless next drops. btw dont keep resetting the white modem, it will cause your speeds to drop as it will think its a line fault, just reset the homehub. if the uptime is less then 2 mins then its dropping fully, if its more than than lets say 1 hour for example (and you reset it one hour ago before the wireless dropped) then its most likely just the router being faulty.

  • WRT310N v1 and MacBook Pro wireless issues

    Hi all,
    I've been having ongoing wireless issues with my WRT310N v1. I have a macbook pro (early 2009) with mac os 10.5.8. I have cable internet, with a DHCP connection. I have a computer and PS3 hardwired through the router, and they work flawlessly. The wireless, however, has never been what it should be. Internet loads slow, even though the connection speed is pretty good (not as fast as hardwired devices, but close).
    Here are the wireless settings:
    wireless config: manual
    network mode: mixed (the Macbook can get wireless-n, by iPhone is only g)
    Radio band: standard 20 mhZ
    wide channel: 9 (can't change this with this config, unless i go wide channel at 40 mhZ)
    standard channel: 11
    SSID broadcast: enabled
    I've got WPA2 security, with AES encryption. I've set the Beacon interval to 75, and left the Fragmentation and RTS thresholds at default. The firewall is activated, and "filter anonymous internet requests" is disabled.I'm wondering if I'm losing so much speed by broadcasting a mixed signal, instead of just G or just N. I've tried transmitting only in Wireless-N, but there's no noticeable change (and the iPhone can't connect at all). 
    Any input at all would be really appreciated. I'm hoping I don't have to fork over $30 to linksys just to get tech support. Thanks in advance.
    Solved!

    Well its not necessary to power cycle your router everytime whenever you make any changes on your Router. But if you re-configure all the settings on your from scratch, then its better to power cycle your router.

  • New MacBook Pro 13 i5 Wireless Issues.

    I got the new MacBook Pro i5 2.3 the day it came out. So maybe a week and half ago.
    I`m having intermittent wireless issues. I have done some testing and even replaced my older AirPort Base Station with the new Dual-Band one, but still seeing a drops from the network. I have a ping going to my router and to the ABSE. I tried changing the channel and using 5GHZ or 2.4GHZ. I also have a AirPort express and seen similar results. I tried reseting the PRAM, repairing permission, I did not reinstall the OS but I dont see how this would help. I think there is a hardware issue with the wireless card/antenna.
    I did upgrade RAM and HDD was changed to SSD (intel G2 SSD). There are no other issues, machine is fast, no lock ups. Other devices on the network do not seem to drop any connections (ATV, ATV2, iPhone4, iPad etc..)
    The network drop outs are short but are noticeable and if a ping is going I can see the drops
    *-- 192.168.1.1 ping statistics ---*

  • Tap to click not working properly in Mountain Lion. How do I get apple to fix this major issue with mountain lion?

    The tap to click does not work with mountain lion as it did before the mountain lion install. I purchased a brand new imac in August of 2011 and got a wireless keyboard and selected the wireless trackpad instead of a mouse.  The trackpad worked wonderful pre upgrade with tap to click. Now after the install of the newest beast, I have to actually press the trackpad rather than a slight tap. I have carpel tunnel and this is causing great stress upon my hand. How do I get apple to fix this major issue with mountain lion?

    Perhaps, I was not clear enough.
    I have an imac purchased in Aug. 2011 which came with Lion 10.6 (two uprades before mountain lion)
    Recently, I just purchased a macbook pro retina with Mountain Lion
    On my imac, my settings allowed me to "tap to click" everything EXCEPT the initial log in at the star up of my imac, again running Lion 10.6
    On my macbook pro retina which has Mountain Lion, I set up the "tap to click" option, but notice that a "hard" click was neccessary when trying to click things. I thought this was a macbook thing (my first one) so I went and upgraded my imac to Mountain LIon, BIG MISTAKE! Now both my imac AND my macbook only have limited "tap to click" options. Before mountain lion I could "tap" to highlight and select text, tap and drag, and many other thiings that Mountain Lion has disabled.
    I am truly surprised that no one has noticed this MAJOR issue.
    Is there a way to uninstall this update, similar to how on a PC you can go back to a restore point.
    On another note even the way PREVIEW has changed is less user friendly, there used to be icons on the bottom right corner of the screen, now I have to double tap and select the option I would like to switch between contacts and thumbnails. This is really annoying and is causing me time when reviewing files.
    Just in case anyone was wondering, I did go to system preferences -> trackpad -> select tap to click
    In fact almost all of the trackpad functions have been selected.

  • If you have a Blue Screen / Error due to Wireless issues (B110a), fix in here.

    For the original thread created by somebody else, please see here:
    http://h30434.www3.hp.com/t5/Printer-All-in-One-In​stall-and/B110a-network-connection-problem/m-p/319​...
    Here's a youtube video of what happened to me: http://www.youtube.com/watch?v=adE1kq36ld4
    I'm reposting it here so it can hopefully help some of you guys if anybody else stumbles across this. In short, my printer was fresh out of the box and I attempted to connect it to the wireless network. It would throw a blue screen on the LCD with an error of B8126AD6.
    I narrowed it down to an issue with DHCP. For some reason the printer connects to the wireless access point but as soon as it tries to get an IP address from the DHCP server it crashes with that blue screen and the error code in the first post above. This look like a massive bug in the printers firmware! For reference my router is a Billion 7401VGPR3 which is acting as my default gateway and DHCP server. I have a Linksys WRT54G as my Access Point for the house. 
    To solve it, I turned DHCP off on my router and then tried connecting the printer to the wireless network. This time it connects fine but you still can't talk to it because it doesn't have a proper IP address. If it still doesn't connect properly, try turning WPA/WPA2/WEP off on your Access Point. Leave it completely open for a moment until you can reach the web interface (as below). 
    To fix the IP issue, I then went into the Settings menu on the printer and printed the "HP Network Configuration Page". Note that under the Wireless menu option there are a couple of different "Print Network Test Page" options. I believe it's the 2nd one that I selected. You'll know you have the right one when it prints out the page with the following info:
    IPv4 IP Address
    Subnet Mask
    Hostname
    Default Gateway
    Primary DNS
    etc, etc.
    Take note of the IP Address from the printout above and the Subnet Mask. My IP was 169.254.73.5 and subnet mask 255.255.0.0. Now I manually configured my computers IP address to be similar (within the same subnet): 169.254.73.10 with the same subnet mask.
    Now you can load up the web interface of the printer using http://169.254.73.5 in my case. (You should also be able to ping the printer at this point too). In here you have a Network tab where you can now manually set the IP Address of the printer. Set the address you want it to be in your network (in my case 192.168.0.3 with a subnet mask of 255.255.255.0 and default gateway 192.168.0.1 and dns server 192.168.0.1).
    Once I clicked OK I changed my PC's IP back to normal, and I can now reach the printer on its IP address set above. YAY!
    The great thing is, in the web interface you get a million more options to play with. You can manually set the IP address, gateway, DNS, wireless settings such as WPA1/WPA2 AES/TKIP Encryption, WPA Passkey, etc. So if you had to set the Access Point to completely Open, setup the encryption again and put the passkey in here. When I did this I had to go back into the Settings menu on the printer LCD and select "Disable Wireless" then "Enable Wireless" to force it to re-join the network.
    Finally I went into the Settings menu again and Updated the software on the printer. I don't know if the new software fixes the bug or not - I haven't tested it (can't be bothered!).

    Many thanks to gardz for an exhaustive overview on this critical problem with the B110a printer!
    I am happy to report that I have managed to set the printer to a static IP and am now able to connect to it wirelessly from my home computers, and also able to use the web apps and ePrint features on the printer. The printer shows the IP address and I am able to use the EWS (Embedded Web Server) to connect to its IP address from my PC's internet browser. The Wireless Network Test Report also showed no problems. I have also completed the Product Update on the printer, and there are no more pending updates now.
    However, the core wireless problem is still not satisfactorily resolved.
    I get the BSOD and blinking-lights error ("Please turn off printer and then on"), only if I start the printer when Wireless is enabled on the printer. If wireless is disabled prior to printer boot, there is no error. 
    The workaround I have adopted for now, is to always switch off the printer's wireless, before switching off the printer, and enabling the wireless setting only when I need to print/scan.
    Is this happening with anyone else? Why would the printer crash if it boots with wireless enabled? If it is already set to a static IP, why would it still conflict with the DHCP on the router?
    My router is perfectly working, it is in the same room as the printer, so the signal strength is good. The printer itself is quite stable except for this crash-after-boot-if-wireless-was-enabled issue on the printer.
    I made the mistake of connecting the USB cable to my primary computer before installing the printer drivers, so even the USB option is not working (Windows recognizes the printer as an unknown USB device). If anyone can point me to the printer drivers (inf files), I would be grateful. The CD does not have the driver files in a convenient location. It seems to be embedded within the setup package somewhere.
    Gardz and PrintDoc, I hope you can help us out on this one. I know many B110a users are struggling with the wireless issues, so HP needs to release a firmware fix and driver update soon. Wireless ought to work out-of-the-box, as this product is aimed at the SOHO users.

  • I have had wireless issues sense Leapord, any fixes yet? its a shame that my wife has to sit in front of our 27 inch imac on a $300 Windows computer to use the web effectively. I have tried all fixes  and some work while others don't but all temporary

    This Lion wireless issue has become more than just an irritation, so much so, my wife has resorted to sitting in front of a 27 inch imac with a 300 dollar Walmart Windows computer to get the bills paid and use the web. And yes, there is not a fix out there I haven't tried over the last year or so, some worked and some didn't, but all were temporary at best. Same issue with my Macair, I wonder if its a hardware issue, like the video card in my 2006 MBP, it went out after the warrenty and then I found out there was a calss action suit going on over it, unfortunately Apple wouldn't cover it and wanted 7oo bucks to fix it, sold that as parts.
    While i really like me Macs, I own three, I may have to bow out and stick with LINUX, that has yet to let me down, anyone know if Mountain will fix this issue? or are we all just waiting for defective WiFi cards to fail at our own expense, PS, got three Macs for sale.

    Sounds like you're getting kernel panics, which are usually, but not always, caused by hardware problems, with memory being one of the regular culprits.
    First thing I would do is to get our your original OS X disks, insert the first one (should say 'AHT version x.x' in small print on the label - if not, find the one that does), and reboot holding the Alt key down. Choose the Apple hardware test, and when prompted, choose the extended test. If you have either of the TechTool programs, they can do similar testing. Does that identify any hardware issues?
    Next, I'd download rember from http://www.kelleycomputing.net/rember/ . This is a memory testing program that you can set to run overnight. Does it come up with any errors? If so, try resetting your memory card(s) by removing and putting back into the computer. Rerun memory test.

  • Macbook Pro (Late 2008) - Windows 7 64-bit, Bootcamp 3.1 - Wireless Issue

    Hi Everyone,
    I have a Macbook Pro (15-inch, Late 2008) model with Snow Leopard and Windows 7 64-bit dual boot. I have done a search and cannot find any reference to this problem on my hardware.
    I have had no issues in Windows 7 when using Bootcamp v3.0. In the last week I have upgraded to Bootcamp v3.1. (completed twice, rolled back in between to prove that the issues was related to the Apple Update)
    After I update to v3.1, I have issues with my wireless network. The network cannot resolve the name for any internet address. I can connect to wireless networks (tried multiple networks), all the DHCP settings seem to be retrieved correctly (Gateway, DNS etc) and I can ping local and machines outside my network without an issue provided I use the IP address. (Skype works - which uses direct IPs rather than names I have found over time)
    As soon as I use a name for a destination for Web traffic, Mail, pinging (any application), my Macbook Pro cannot resolve the address and just bombs out.
    If I connect to a wired network, the machine works perfectly and name resolution on that interface works. If I rollback (using Windows 7 rollback capability) to before the v3.1 Bootcamp is installed, the wireless networking also works perfectly.
    I noticed this in the support area at apple:
    http://support.apple.com/kb/TS3196
    But this refers to wireless issues in Bootcamp drivers prior to v3.1 and on 13 inch Macbook. Wonder if this is a similar issue or related?
    Anyone else seen this or point me in the direction of a fix?
    Thanks,
    Thommo

    I'm looking into running Windows 7 64bit on the exact same MBP you have, so I'm curious as to whether or not you've found a solution yet outside of the forums.
    Do you think it might be that the bootcamp 3.1 update is only for Windows 7 32bit and not for the 64bit version?

  • MacBook wireless issue (ongoing) & DIY airport card replacement

    Hello,
    With reference to the ongoing MacBook/OSX (10.5.3) Leopard intermittent wireless issues discussed in this forum has anybody gone ahead and taken matters into their own hands and purchased and installed a new Airport card for their MacBook from www.ifixit.com?
    Further details at: http://www.ifixit.com/MacBook-Parts/MacBook-Core-2-Duo-Santa-Rosa-Penryn-802-11n -Airport-Extreme-Card/IF186-062
    If so, did it resolve your intermittent Airport issues?
    It seems to me that when the MacBook is running on battery power only the Airport card does not realise that the MacBook has come out of sleep sometimes and therefore does not always function correctly. Maybe the Airport card does not receive sufficient power when the MacBook comes out of sleep mode whilst running on batteries only?
    Typically when I run the MacBook connected to power the intermittent wireless problem does not occur.
    This issue has been a recurring problem for me for 6 months now and unfortunately I have not seen Apple address this issue.
    My MacBook is 6-months old and is a black MacBook using a 2.2GHz processor running Leopard OSX 10.5.3.
    Cheers,
    treaders

    Visit Apple Store and replaced the Airport card.

  • Wireless Issues with Apple TV 2nd generation

    I have a linksys wireless router using WPA2 wireless security.  I have 5 laptops, 2 printers, 3 iPhones, and 2 iTouch's connected to the wireless with no problem.  My apple TV (second generation) has wireless issues, it will sit and connect and disconnect then reconnect then disconnect back and forwarth over and over.  It is the only device on my network that has issues.
    BTW,  I have an AppleTV 1st Generation that also has no issues.
    Any suggestions would be appreciated.

    Yes it is wireless and it is right next to my Playstation 3 that has netflix along with several internet games and is also wireless but has no problems.
    NEW INFO
    Upon further inspection.  It appears that my wireless is connected and I am logged into my itunes account but I only see 3 main categories at the top (Internet, Compouters, Settings) instead of (Movies, Tv Shows, Music, Computers, Internet, and settings).
    I have confirmed that my photo Stream from my phone is working and updated.  However, No YouTube access so no internet.  However, I know I am getting to apple because if I enter an incorrect password it tells me and also it stores the username/password.
    Not sure what to do.  I thought it was the wireless and still might hardwire the connection if I can but this is strange.  I have setup many ATV2 and have and ATV1 with no issues.
    Thanks for your help!

  • Wireless Issues after 10.4.7 update

    Hi all,
    My wireless connection was solid since the day I bought my Macbook Pro. I had profiles connecting to my wireless router at home and my work wireless points at work. When I recently updated my system to 10.4.7, I have had some issues with my wireless.
    Sometimes when I start my mac up, login, etc, the wireless icon in the system tray will flicker, and I have no connection to my wireless. If I disable and enable the Airport device, sometimes it just starts working. Sometimes I have to reboot the system to make it work. If the icon does not flicker, it works fine, when it gets into that state where it doesn't work, the icon flickers.
    Anyone else having these issues?
    Macbook Pro 15" 1.83GHz   Mac OS X (10.4.7)   1Gb RAM

    I also had some dropped connections over my wireless
    router at home (Linksys router) after the 10.4.7
    install. I have a MBP 15" W8617xxxx. Connection was
    good for a few minutes at a time. Then I had to
    restart AirPort.
    For me, I had installed some other apps about the
    same time as 10.4.7, so I uninstalled them, repaired
    permissions, installed the Combo 10.4.7 and now
    everything seems okay.
    I don't know if it was the new apps, or the Combo
    install, or repair permissions, or ?
    Hope that helps. Good luck.
    =================
    SDDave,
    i have been reading a lot of postings regarding the issues with wireless after the 10.4.7 update.
    i also have a linksys wireless router and have identical problems with you. i am sure many of us do as well.
    you said you managed to install the 10.4.7 combo and everything seems to work properly now? if so, would you be kind enough to give me detail steps on how to install the 10.4.7 combo file
    1. do we get the combo 10.4.7 from the apple site?
    http://www.apple.com/downloads/macosx/apple/macosxupdate1047comboppc.html
    2. what steps do we need to install this file?
    please please help us out to provide detail steps to do this. i know some of us here are not as comfortable doing it without some help.
    i would appreciate if anyone else would help out beside sddave.
    thank you in advance. i can't wait to install this combo update to resolve this connection issue.

  • Head Scratcher - Default Field Values

    have an issue that is truly a head scratcher and I could use a little help.
    I created a number of fields - client name, client email, account manager etc. Most are just Unicode a couple are integer and one is a date. For two of them Client Name and Account Manager which I'm going have a lookup attached I enter a default value. Choose Client and Choose Account Manager.
    For two of the fields (client name and account manager) I created lookups with a list of clients and the other with a list of account managers.
    I then created a new group added all of the custom fields. For the two fields I want lookups on I select them in the group window and attach the lookups that I've previously created. I continue with where the group appears, attach it to a set etc and then save changes.
    So everything is perfect I can see the group within the set but for the two lookups I don't have a default value just a blank pull down window. What's the deal. Is there a syntax I'm missing for entering the default value for the field? Do I also need to enter the default value in the lookup so they match?

    actually the issue was with putting the default value in the lookup. That worked. I get what your saying though, however its really six of one half dozen of another. I created the fields first so editing the field in the lookup pulldown I didn't actually have the correct lookup values.
    By creating the field and then lookup and then linking them up in the group it worked just fine. But after I read your post I created the lookup first and then attached it while creating a field and didn't attach it while creating the group and got the same result.
