Upgrade 10 Mbps connection to 100 Mbps

I replaced my old PC (pentium 4) with a new PC (quad core) in my network (Xbox360 (wired), Wii (wireless), Laptop (wireless) and this PC (wired) on a WRTP54G Voip Router). With my old PC I had no problems, but now I get the message network cable not connected on my new PC. The solution is to reduce my speed from the 1GB Nvidia LAN to 10Mbps full duplex instead of automatic (100 Mbps didn't work). Now it connects to my router, network and internet with 10 Mbps, but this connection is too slow for my network. When I connect my laptop directly with the PC I will get a 100 Mbps connection. And when I connect my Laptop to the router with the same cable as the PC, I also get a 100 Mbps connection.
Can someone explain the difference between half duplex and full duplex speed?
Is there a solution to get the connection to 100 Mbps?

Full Duplex = your NIC can send and receive data at the same time. A telephone is an example of full duplex, both parties can talk/here at the same time.
Half Duplex = your NIC will either send or receive data but will not do both at the same time. A walkie talkie is an example of Half-Duplex, only one person can transmit at a time.
Sorry I do not deal with the gaming part at all, so I do not have a solution, however if I come across an answer I will certainly post it.
Good Luck,

After upgrade my MBP from snow leopard to mountain lion all my smb connections stop to work.
Now iám using mac os 10.8.2
I can see the server, I can choose the drive, but when try to open a folder the message on Finder is: You don't have permissions to see the content.
I already delete the key and try to connect again, but the problem persist. Already try change the ip from file server. Already try differents users. (admin, guest, etc...)
I have a windows server 2008 and a NAS working with SMB protocol. Both with the same problem.
That problem occurs only on Finder, if I try see the folder by Terminal, is possible to see my files.
Any Solution ?
Any Tip ?
Any Question ?

Not knowing how much RAM is installed in your iMac, your iMac can take a total of 8 GBs of RAM.
Before upgrading to Mountain Lion, I would strongly suggest installing the maximum 8 GBs of RAM.
Correct and reliable Mac RAM can be purchased from online Mac RAM sources Crucial memory or OWC (macsales.com).
Here is OWC's link to your model iMac and the RAM modules you will need.macsales
http://eshop.macsales.com/item/Other%20World%20Computing/8566DDR3S8GP/
You can purchase and download OS X 10.8 Mountain Lion from the Mac App Store in the OS X dock.
Before installing, it would be prudent to make a backup copy of all of your important data or your entire current system. Either using, optical discs, USB flash drives or external hard drives.
This is too insure protection of your data in case something goes wrong with the install of OS X Mountain Lion.
Good Luck!

Reboot the machine holding Command and r keys down, you'll boot into Lion Recovery Partition
In there will be Disk Utility, use that to select your Lion OS X Partition and Repair Permissions.
After that is done reboot the machine and see if you can log in.
If not repeat the above steps to get into Lion Recovery, get online and reinstall Lion again, it will overwrite the installed version and hopefully after that it wil work.
Reboot and try again.
If not follow my steps to create a Snow Leopard Data Recovery drive, then option boot from it and grab a copy of your files off the machine.
Then reinstall all your programs onto the external drive like setting up a new machine, then use Disk Utility to erase the entire internal boot drive (select the drive media on the far left, not the partiton slightly indented) format Option: GUID , 1 partition OS X Extended and then use Carbon Copy Cloner to clone the external to the newly formatted internal drive. Once that is finished reboot and disconnect the external drive.
Once you go that, boot into Snow Leopard and update to 10.6.8, use the AppStore and option click on Purchases and download Lion again and install.
Lots of work, but there is no Lion disks.

How to upgrade my MBP glossy screen to antiglare??

I already purchased the MBP 15 however I want to change the screen to antiglare. I know I can install an antiglare film but this hits the image.
How to upgrade my MBP glossy screen to antiglare after I already purchased the MBP? Is it possible to do it through apple?

That would mean replacing the top cover of hte MBP, something on the order of $500...and would have to be done by Apple or an authorized Apple repair or it will void the warranty. You could try talking to an Apple store genius bar person and see if they would do that but it will not be cheap.

've never used a Mac before, recently i purchased a MBP13" which came loaded with LION OS by default. I upgraded the OS to OS10.7.2 when prompted. Now after the upgrade, my MBP feels very slow - specially when typing emails !! What is the solution ??

After an update or installation, your MBP may take some time to index its files. Give it some time - but if you don't see any improvement, post here - you'll get an answer!

How do I downgrade from Lion to Snow Leopard without losing iWork 09? I upgraded my MBP from 10.5 (originally 10.4) to 10.6, then again to 10.7. Should I go back to 10.4, 10.5 or just to 10.6?

Thanks for the information! My sister gave me the MBP for my daughter with Leopard installed. I purchased Snow Leopard and installed it, then my daughter purchased Lion. So I do have all the installers. If iWork wasn't included with any of those, I guess my sister purchased it while running Leopard. I'll have to contact her. Thanks again.

Thank you.

The most reliable sources for Mac compatible RAM are OWC and Crucial. Macs seem to be selective with RAM so some brands will not work. Make certain that you get RAM with the exact specifications that apply to your MBP.
Ciao.
If you have a need, be advised that you MBP can actually support 16 GB RAM.

Mountain Lion OS upgrade on MBP 2008?

Would you suggest upgrading a MBP 2008 with the Mountain Lion OS? My computer runs like the day I bought it but im concerned with all the chit chat about compatibility that I may get myslf into trouble here.... I do have Lion on it currently and have no issues......

Before upgrading consider:
Don't upgrade if you are in the midst of important work. Wait until you have finished.
If you are having problems with your computer get them sorted out before you upgrade.
Verify that any mission critical software will be compatible with the upgrade.
Do you need the upgrade?
Make a bootable backup of your current system before upgrading. This will make returning to your previous system easier should you decide to do so.

If you bought the MBP new 3 weeks ago, it should have come with Mountain Lion already installed. Did you update your MBP to the newly released 10.8.4 update? If not, what OS were you running before the upgrade, and what version of Mountain Lion do you have now?

Error during upgrading Cisco Unity Connection to SU2

Help!
I'm facing an error while upgrading Cisco Unity Connection 8.5.1.10000-26 to SU2 (8.5.1.12900-7).
When it's trying to download the SU2 file (UCSInstall_UCOS_8.5.1.12900-7.sgn.iso ) to Unity Connection after 2GB I get this error:
Error encountered: Upgrade has detected that the ISO file name has been changed from the original name. This is not allowed. MD5 Hash Value: 32:32:db:47:99:48:c6:53:12:e2:78:76:94:90:a4:1d
I tried this from multlpe FTP servers and I downloaded the SU2 file multlpe times assuming the download was bad. I also rebooted the Unity Connection server here and there assuming it was something with the server.
I first tried SU1, but that gave the same error, so I attempted to go with SU2.
Any ideas for resolving this?
Thank you!
-rya

Hi Rya,
OK...well you've certainly done your due diligence here
Did you run an MD5 check after the download to compare the file values?
I had a long look for bugs related to this issue and came up empty so I can't see
a bug being the cause of the issues here. Is it possible for you to try "burning" the
upgrade .iso to a DVD and trying again?
I am also curious why you wouldn't move straight to 8.5(1)SU4
Cheers!

Am I the only one experiencing battery drain with the 6.1.3 upgrade? It went from 100% to 63% in 7 hours WITH NO USE!

Am I the only one experiencing battery drain with the 6.1.3 upgrade? It went from 100% to 63% in 7 hours WITH NO USE! I've had worse luck with the i5 than the i4. This is the first time I regret being in a two year contract. I might add that this is my 3rd i5

So now 12 days later and another replacement I'm still having issues and apple still isn't helping. My phone has started shutting off unexpectedly again today. Does anyone have any suggestions on where to go from here?

Noob here, wanting to upgrade my MBP HD to 1TB.

So I'm looking to upgrade the internal hard drive of my February 2011 13.3" Macbook Pro. It's 2.70GHz i7, 8GB RAM, current 500GB HD. Does anybody know what a good option would be? Preferably under $100, unless you can convince me that a more expensive one is worth the price difference
I also read a bit that some hard drive upgrades can slow down the computer, which I'd like to avoid as much as possible. But yeah, I just really don't know much on this stuff, so any help would be awesome.
Cheers!

Any 2.5" SATA Hard Disk Drive that is 9.5 mm thick will work in your MBP. HGST and Seagate have performed well for me. I have several 1 TB HDDs from each of those manufacturers. Look at this link for possible selections:
http://eshop.macsales.com/shop/hard-drives/2.5-Notebook/
Though a HDD with a faster rotation will enhance performance, it will not be as great as the speed differential suggests. A 5400 rpm will be satisfactory if the budget is tight.
Ciao.

What is the best upgrade to MBP 13" 2010

What's up!
I going to the USA (miami in fact..) and i was wondering if some shopping to upgrade my MacBook Pro C2D 2.4, 4GB would be nice... i already have upgraded the hard disk to a 7200 RPM Seagate with 320GB
I was thinking in two things.... but i wanted to know if there is going to be a real difference. i'm looking to spend 100 USD on the upgrade...
One: A seagate momentus XT 500GB hard drive
Two: An Corsair 8GB DDR3 memory kit
I'm a light user... the most demanding software that i use is Valve's Counter Strike
On AJA test software, my HD gave me 71,2 MB/s on it's tests
Other sugestions are really welcome!
Thanks from Brazil!

My question is, there is going to be a real difference on the performance, load times, boot up?
Remembering that i'm a light user...
There are many variables, so no one can say for sure. That said, one way to get an idea whether more RAM will help or not, is to check Page outs and Swap used. First, use your Mac as you normally would, the longer the better (checking this right after starting up isn’t likely to show you anything). After you’ve used your Mac for awhile (again, the longer the better), go to Applications > Utilities > open ActivityMonitor > in the top menu at right, select All Processes in the drop down menu > near the bottom of the window click on System Memory. If Page outs is more that about 10% of Page ins, and/or Swap used is large, chances are good that adding RAM will help.
