Network slowness in lion 10.7.2

I am having network slowness ever since upgrading to Lion 10.7.2. Nothing in my setup has changed. I used to get around 10 Mbps on my DSL router, now I get about 6 Mbps. I checked the router, the signal coming in to it is the same strength, 12 Mbps. Anyone have any ideas?

I use the word "Excessive" because when I boot from an external drive, where I have Snow Leapord installed, and open the same links, I don't have the list of ports and I never lose any with a "server not responding" error. The log in VirusBarrier doesn't show the time of the connections or how long they remain open. Not sure where I could get that information.
Not sure if a Netstat reading from the Network Utility helps with any info.
The clean install of the Mac OS 10.7.2 on a seperate partition yielded the same results.

Reviews say Aperture runs really slow with Lion, any suggestions?
To add on to Corky02 answer:
The recent Aperture release AP 3.3.x is very efficient, both on Lion and Mountain Lion. But you need a decent hardware to support it. The older Macs will have problems with the storage and CPU requirements. For good performance on large raw images plenty of RAM is important, at least 4GB, but 8GB would be much better, and your library should be on a fast disk, preferably on an internal drive. And don't let the system drive get too full.
Many reports about Aperture being slow are due to putting the Aperture library onto slow disks or acessing the original image files over the network, insufficient RAM, or corrupted or ill-designedAperture databases.
Aperture excels at all kinds of image processing that can be considered image developement - raw processing and color/lighting adjustments, but does not do compositing. If you are shooting raw and want professional image developement I'd recommend to do this in Aperture and not in iPhoto - you will have much more control over this in Aperture (after a steep learning curve). You can also repair and retouch the image to correct minor blamishes. For graphics compositing and inpainting you can set up an external editor and send your images from Aperture to this external editor - any of the editors Corky recommended would be o.k. for this.
To see, if you will want the advanced image processing in Aperture or the easy to use, more basic options in iPhoro will be sufficient to you have a look at the Aperture User manual, or the tutorial on the support page: Aperture Support
But Aperture is a professional apllication, not "plug and play". You should only consider it, if you are willing to spend some time on learning to use it properly and are willing to work your way through the manual.

Time Capsule slow in Lion and errors

hello --
ever since upgrading to lion i am having a lot of problems with my time capsule. it is running extremely slow, while before it was perfectly acceptable over wifi. eventually i installed the time capsule buddy widget and noticed the error below repeatedly occuring (in bold). i also noticed that all of a sudden it requires 1.89 GB to backup ( !!! ) in the last line, something that never was an issue before. have others encountered similar issues?
thank you in advance.

A: Time Capsule slow in Lion and errors

Same problem here - slow backing up to my Time Capsule. Today I had some trouble after booting my MacBook Pro. Finder got stuck and after some restarts Spotlight re-indexed and everything seems fine. And now backing up is much faster. I used to have a lot of time waiting for indexing. But I still get this error message:

But it seems that everything is working fine. It's backing up and I am able to restore files via Time Machine.
Should I worry?
Any clues?

Aperture 3 very slow on lion

running on my macbook pro 2.66 ghz core 2 duo with 4 MB of ram, aperture 3 was lightning-fast in snow leopard, now is mud-slow in lion. as in *unbelievably* slow. is a fix coming?
f

I had taken the route, over time, of installing Lipn, ontop of SL, ontop of Leopard -- after the upgrade to Lion, Aperture became painfully sluggish. After scouring user forums and a lot of Google searching, I found the one suggestion where you delete cache from a couple directores and a .plist from Aperture. No real difference.
Finally, after, what I would assume to be frustration and morbid curiosity, I used Onyx's automation clean up tools (checked everything but reindex Spotlight), and went the route of trashing my preferences. Full contents.
Long story short, Aperture is in the process of importing and processing about 59k photos and remaining much much more responsive. Instead of taking 36 hrs to complete like before, it's on track to complete everything in about 6.
Lion, as a whole, also seems snappier.
We'll see what happens when Aperture completes processing, but I am a lot more optimistic. I suppose should THAT fail, i'll go the clean-install route.
But, yeah, installing OS ontop of OS ontop of OS is never a good idea, no matter what anyone says -- you wind up with some cross tangled schmutz...

Network slow after 10.4.5 update

Hi there, after installing the 10.4.5 update my PowerBook 12" is really slow when accessing network services. Web, Mail are impossibly slow.
I have a cable modem broadband connection with a Belkin wireless router sharing the connection. The laptop connects via Airport and uses DHCP for autoconfiguration.
I have tried the fix suggested on MacFixit of putting the DNS manually in the TCP/IP settings. Also I have turned off IPv6 which was also suggested to no avail.
My other laptops with earlier system revisions are running fine (I am using one to write this) and I have tried the Mac on another network with the same effect so it has to be something that 10.4.5 has done to my poor alubook
Can anyone help please.

Mac OS X 10.4.5 (#9): Another fix for network slowness -- re-applying the combo updater; SIIG FireWire card not working; more
Another fix for network slowness -- re-applying the combo updater Over the past few days we've outlined a number of fixes for network slowness that occurs after the update to Mac OS X 10.4.5, including entry of a DNS address, toggling of IPv6 and more.
We've now received notes indicating that a tried and true workaround for various issues -- re-applying the Mac OS X 10.4.5 combo updater (as noted in our general workarounds for 10.4.5) -- can have beneficial effects in this case as well.
MacFixIt reader Fred Moore writes:
"After much thrashing about and wasted time, I appear to have solved both the slow web page loading as well as my email sending problems in one stroke. Guess how: download the Mac OS X 10.4.5 combo updater and reapply it. This nonsense has cost me a lot of time but everything seems to work now. IPv6 is set back to Automatic, there is no entry in the Network prefs DNS server field, and my email sending works perfectly (so far; I've sent a bunch of tests). Why didn't I just download the combo updater and apply from my hard drive at the beginning? Well, Software Update should (yes, I know, I know...) work. I'll never again use Software Update for a system update."

Does a mixed N and G network make the network slower for the N-enabled?

Hello all,
I was just admiring my Airport Extreme box after registering it, and I noticed this bit of fine print:
"Speed and range will be less if an 802.11a/b/g product joins the network."
Does this mean that my 802.11g printer makes the network slower for my two 802.11n macbooks?

Okay,
For a follow up: I'm using the "guest" network for all my G-level wireless devices, and the regular network from all my N devices.
Does that overcome the mixed network limitations? It seems like it wouldn't - because the Airport is basically creating two virtual networks out of one network. Or are there two individual networks on the Airport?
Thanks!

Extending Airport Extreme Network Slows Network Dramatically

Hello, after I extended my airport network I experienced dramatically reduced network speeds. Here is my configuration:
ISP is cable modem with very decent speeds.
Base Station is Airport Extreme (802.11n capable) / with gigabit ethernet (in garage)
Secondary router is Time Capsule 802.11n WiFi hard drive (also gigabit ethernet capable (on my desk at other end of the house).
What works OK is connecting base station to secondary router using ethernet, base station with wireless enabled, but secondary router (Time Capsule) with wireless set to Off. I have the latest versions of Airport Utility and firmware installed everywhere.
"Ain't broke, don't fix it" you may say, BUT I did want to extend the range of the wireless network. So I followed the steps to extend an 802.11n wireless network:
( - Base Station: Create Network / Allow network to be extended;
- Remote Station: Extend Network, selecting my network, allow wireless clients)
Everything seemed to complete successfully; two green lights glow in Airport Utility and one on each device. However, the network slowed to a crawl. It was so bad that I had to back out the changes and revert to my initial configuration. The extended range of my wireless network was just not worth the terrible performance penalty.
The network slowdown seems to be experienced by all clients, including another Mac which is connected via Ethernet to the Gigabit Base Station (not to the Time Capsule - directly to the base station). So this suggests that the extension to the wireless network slowed down the whole network. (Btw, it's not just internet connections that were affected. I tried connecting between the Macs using the Finder and it was painfully slow - taking roughly a minute to connect.) To me it seems that something must be very wrong, I just don't know what!
So my questions:
1. I had hoped that the gigabit connection between the routers (which seems to work fine when only the base station supports wireless clients) would continue to work when the Time Capsule is used to extend the wireless network. Is this true, or in this mode does it switch to operating as a wireless client itself? (If so, this might partly explain why my office Mac slows down so much; it would now be connecting to the cable modem via wireless, not gigabit.
2. I'm guessing, (but I haven't tried it yet), that I might be able to achieve almost what I want to do by creating a different network using Time Capsule. Does anyone have any experience doing this? If so, what suggestions do you have?
Thanks, Patrick

Patrick... I had the same problem althjough not quite as complex I believe... see this thread... http://discussions.apple.com/thread.jspa?threadID=2111176&tstart=0
I changed my base to 'n' at 5ghz and saw a marked improvement. Hope this helps.

Very Slow Internet Lion (This one is for the "Apple Network Team")

hello,
i'm joão from Portugal, Europe.
a couple of weekends ago i've updated three macs to Lion.
2009 MacMini, 2007 White Macbook, 2010 iMac 21".
problems? only with the iMac.
no connection drops but slow slow slow very slow internet. wired, speedtest marked 15Mbps download. wireless? 1Mbps, 0,3Mbps, 3Mbps, very unstable.
with Snow Leopard everything was ok.
tried every solution from every site and finally got it working flawlessly.
tried clean install instead of update.
tried new dns servers.
tried disabling ipv6.
tried remove wifi interface then add it again.
tried service order.
tried PRAM, NVRAM, SMC, you name it, reset.
tried removing preferences folder.
tried different browsers -> same symptoms.
tried disable/enable airport.
tried 10.7.1, 10.7.2, combo, delta.
tried router's firmware update.
tried putting the computer closer to the router.
tried resetting the router, factory defaults.
tried changing router's channel.
tried disabling router's firewall.
tried watch router's event log, nothing suspicious.
tried disabling router's wep password.
tried pinging a site for a couple of minutes, 2% packet loss.
tried hundreds of pages and forums...
during this attempts, macmini and macbook showed very good wireless internet speed.
iMac? slow, slow, slow, slow, slow, like seeing gmail's loading screen for more than one minute...
again and again speedtest 1Mbps, 0,3Mbps, 1Mbps, 1Mbps, 0,3Mbps, 3Mbps.
discovered the pingtest utility in the same site and iMac's ping was grade C, grade F, grade D, with big values...mac mini and macbook were alwas grade B, with low pings (imagine 25ms on them vs. 138ms on the iMac).
i was fed up with the situation, every week tried and failed. iMac's owner was wanting to get his Lion money back and stick to Snow Leopard again. imagine recent Windows switchers thinking they went back to the same situations....
but then i found this website. and then realised macbook and macmini's wi-fi were both powered by a broadcom chipset. iMac's was powered by an Atheros chipset! did what the guy says on that site (replaced Lion's Atheros kernel driver by the one on Slow Leopard), and now everything is perfect, like on Snow Leopard. very good speed.
what a relief. thank you sir.
hope it can help you.
hope it reachs apple's network developers...this is not good, you can't fail on something so simple and essential as decent wifi quality...

humm...
i've clean installed one macbook (late 2008?) and one mac mini (early 2009) both with broadcom adapters and both of them were ok, after the install.
so, speedtest and pingtest are websites (speedtest.net and pingtest.net), both test your internet connection with the help of a 'local' server. it's useful, for instance, if you want see if two different computers connected to the same router have the same connection quality.
so if you can connect to some routers nicely and you have problems with your router, to me, it seems like you have some problems with the connection between your computer and the router.
an old router might bring you problems (there are some advices on the internet to change router's channel and so...), i would recommend to see if motorola has some sort of firmware update to your router. if you don't have complex router configurations, you might try to reset to factory defaults (search the manual). that, once, fixed a problem with a smc router and two macbooks (one, older, could connect easily, the other wouldn't connect to the router).
if that atheros driver trick, resolved your issue, that's strange
make sure broadcom isn't your ethernet adapter and not your wireless adapter
did you resetted your pram and smc? do you have Mac OS 10.7.2?
i hope you can figure that out.

Network Refresh on Lion?

One of the more common hassles I deal with in Lion is the very sluggish network refresh.
I'm on a medium-sized network composed mainly of OSX machines, and sometimes one of them will reboot and come back with a different IP address. When this happens it will take an excessive amount of time for Finder to update the new computer address on the "Shared" section.
Can't this be done manually? How come there's no option to simply refresh all network assets?

I have the same issue with my 2013 Mac Mini Server (top of the line specs, 16GB RAM, etc) over a GIG-E local network directly connected to the same switch. I've tried different cables and ports to ensure it's not a network issue. Ironically enough, I get a solid connection with the Windows RDP client on my laptop to a Windows VM running on that same server; but when I try to directly connect via ARD, I get the slow refresh / blocked appearance you see in the attached screenshot.

Wireless slow since Lion upgrade

Is anyone else finding that their wireless is slow after updating to Lion? My desktop is plugged in and fine which leads me to believe it's not Comcast but my laptop, iphone and apple tv all of the sudden are not working well. Especially the apple tv. Did something change in the update that would affect the wireless router?

I use only wifi, and my laptop is fine.
Have you noticed any new wireless networks popping up in your area?
Wireless networks can be slowed down by interference.
Eg: If you have new neighbours, and they recently added a wireless network which is close enough to your network, they will interfere with each other.

Trouble searching network folders in Lion

I'm having trouble searching my work network folders now that I have installed Lion. It is a windows network and snow leopard was always slow to come up with results but I always knew it was working when the little spinner showed up in the bottom right corner. In lion when I type in a seach term in finder, it shows me nothing and there is no indication it is doing anything, even when I know the file is already there. It seaches my hard drive very fast as that is indexed.

We're having this exact same problem.
Shared files on a Windows server are not being searched by Lion. It was perfectly fine pre-Lion but now nothing is showing up in search results (even files I know are there).
We need a fix for this as soon as possible.

Airport Drives Me CRAZY! New 802.11n Network Slower Than Old 802.11g/b

I've been using Macs since 1988 and consider myself an advanced user. However, every time I setup a new Airport wireless network or re-configure an existing one, I feel like a helpless newbie trying to figure out how to open a folder on my desktop. No matter how many times I read the manual or the help files or these forums, I can never grasp what seems like it should be a simple path from A to B to C.
Anyway, here's my current situation: I've been successfully (I think) running a 6 year old AP Extreme Base Station [AE] (in my home office addition) and 2 Airport Expresses [AX] (one AX roughly 15 feet from the base station--through sheetrock, and the second AX roughly 30 feet from the first AX--through sheetrock and some wooden stairs. (so roughly 45 feet from AE to 2nd AX). It wasn't the speediest thing going but it did the trick with older Macs.
I recently bought a MacBook Pro which supports 802.11n. I most often use this laptop at the point in the house furthest away from the AE (Base Station) The AE (Base Station) is in my home office connected to my MacPro desktop (see #1 below). In addition, the family iMac is also in that room furthest from the AE. Using the new MacBook Pro with the old 802.11/g/b network turned out to be painfully slow. I was experiencing the same slow network connection my family has complained about for years with their older Macs and 802.11g/b.
I decided it was time to upgrade the whole network, if only to speed up my MacBook Pro connection. Bought new 802.11n Airport Extreme (MC340LL/A) and 2 new 802.11n Airport Expresses (MB321LL/A). Setup did not go smoothly. Again, my normally competent Mac persona was reduced to a babbling three-year-old. Had three different Apple techs on the phone trying to help me through it. Got different, contradictory instructions from the last two. Finally got all three units working, only to find that not only does my MacBook Pro seem even more sluggish than when connected to the old 802.11g/b network, but my wife tells me web pages are taking at least twice as long to load as with the old network.
As concisely as I can lay this out:
*1. Airport Extreme (Base Station)*
Connected via Ethernet from its WAN port to my Comcast cable modem. One Ethernet (LAN) port on that AE is then connected via Ethernet to my Netgear 8-port Ethernet switch. Ethernet from switch to Ethernet port 1 on my MacPro. (MacPro does NOT have an Airport card because I forgot to order one. Also I confirmed that this setup was functional by connecting to the AE wirelessly with my MacBook Pro showing the name I'd given the new network prior to adding the two AX's to the mix).
Some Airport Extreme settings of note (all accessed via "Manual Setup" button):

SETUP/GOALS:
With Airport Extreme (Base Station) as the starting point, have the two Airport Express units with the strongest, fastest signal possible, provide Internet access (and file sharing, iTunes speakers capability) to three Macs (one older iMac, one older PowerBook and my new MacBookPro). Again, I believe my new MacBook Pro is the only one with 802.11n support, so I don't expect the other Macs to take advantage of the speed boost offered by the three new 802.11n devices.
+Any and all help with this will be greatly appreciated. Thanks!+

{quote}With the AirPort Extreme, in the AirPort panel, Wireless tab, click on the button for "Wireless Network Options", check the box for "5 GHz Network Name", and enter a different network name. (That can be trivially different, such as the name of the main network suffixed with an underscore and the digit 5.) Once configured that way, connect your "N" gear to each network in turn to see if one is any better than the other. (If you're wondering what effect this would have, it allows segregating your "N" gear from the older gear to prevent the older gear from slowing down your network. However, distance and interference from things like walls may negate any advantage.){quote}
William: I was gone most of yesterday, but had a chance to implement your recommendations today. I added the 5 GHz network as you suggested, but in order to connect to that at all with my 802.n11 MacBokk Pro, I need to be within a few feet of the AE (base station). If I try to access that network even from the next room (well within reach of both the AE and the livingroom AX, I get one bar and "failure to connect" messages just trying to logon to that network.
However, I did some experimenting that (as of right now, anyway) resulted in much faster network access, not only from my MacBook, but also from the older iMac which is the furthest Mac from the AE. According to my wife, that iMac is "loading web pages faster than I've ever seen them!"
Here's what I did:
1. Moved all three units to places where it seemed they would have the least amount of interference with the clearest path from unit to unit, also raising the height of both AXs from about 2-3 feet from the floor to about 5-6 feet from the floor.
2. Changed one setting on the AE (base station): Wireless Tab > Wireless Network Options > Multicast Rate ---> Changed this from Low to High.
I have a feeling the location shifts made the real difference, but I will try changing the multicast rate back to "Low" just to see what happens.

Macbook Pro 2011 running slow - mountain lion

Hi,
Since updating to mountain lion my mbp is running very slow,
Have repaired disk permissions and ran clean my mac but no improvements.
The hard disk is less than half full and no login items up on start up.
What more can I do?

So it's the 13" (early 2011), MC700LL/A (2.3 GHz)? You can install up to 16GB of RAM in that machine, although Apple only 'officially' endorses 8GB. I run 16GB and find that I actually use up to 13+GB at one time - but I'm able to run many memory-hungry apps concurrently with no swaps, etc.
If I were you, I'd install at least 8GB - take a look at the Crucial site and click the System Scanner. You'll be offered the recommended upgrades.
As to a clean installation of the OS - I wouldn't really worry about that at this time. It doesn't sound as if you've an OS/software problem... there's no telling why your friend's MBP (the same as yours?) seems faster.
Good luck,
Clinton
