Wifi extremely slow when not right next to the router?

Hey,
bought a new macbook air last week with Mountain Lion (I've fully updated it) and it seems to be having a few wi-fi problems. Although wifi speed is fine when in the same room as the router, the speed drops of significantly when in just the next room, and even small sites take about 10 seconds to load. I'm using an Virgin Media 54g router but the problem remains the same with a Belkin 54g router as well. The recieved speed in my room (a couple of floors up admittedly) is 11 and speedtest.net shows a 0.05mbps download speed and (strangely) a 1mbps upload speed when I can connect at all.I haven't yet had the oppurtunity to try n or 5ghz routers, but as the rest of the network uses the Virgin Media one, I'd like to be able to reliably connect to this.
I've tried suggestions online such as creating a new location, disabling bluetooth, tried a new user, a new router and renewing DHCP lease etc. but nothing seems to work.
Does anyone have any suggestions to try? I'm not sure if this is a software or hardware issue, but I thought this was the most appropriate place to put this.
Thanks in advance,
George Bryan

It's normal, of course, for Wi-Fi performance to fall off with distance between the client and the access point. Whether your MBA is performing normally can only be determined by taking it to an Apple Store or AASP for testing.

Hello, I have a macbook pro late 2011 15 inch with 4 gb ram. My macbook runs extremely slow when logging in after waking up from sleep, locking up and I am unable to use the keyboard. Is there a fix?

My macbook runs extremely slow when logging in after waking up from sleep, locking up and I am unable to use the keyboard. Furthermore, when just using safari to watch streaming television, my computer gets really slow, and locks up, and the dock appears blank and I sit here frustrated. Anytime i wake up my computer, my keys don't respond and I've waited at most 3 minutes untill i can type in my password. Even sometimes when i type in my password and hit enter, it takes forever to open up my mac. I have barely used any storage in my macbook, since i only use it for college, and I have run clamscan wiht no viruses showing... Any ideas?

Please read this whole message before doing anything.
This procedure is a diagnostic test. It’s unlikely to solve your problem. Don’t be disappointed when you find that nothing has changed after you complete it.
The purpose of the test is to determine whether the problem is caused by third-party software that loads automatically at startup or login, or by a peripheral device.
Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards. Boot in safe mode and log in to the account with the problem. Note: If FileVault is enabled, or if a firmware password is set, or if the boot volume is a software RAID, you can’t do this. Ask for further instructions.
Safe mode is much slower to boot and run than normal, and some things won’t work at all, including sound output andWi-Fi on certain iMacs. The next normal boot may also be somewhat slow.
The login screen appears even if you usually log in automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin. Test while in safe mode. Same problem? After testing, reboot as usual (i.e., not in safe mode) and verify that you still have the problem. Post the results of the test.

Zen X-Fi2 extremely slow when loading playlists!

0Zen X-Fi2 extremely slow when loading playlists!?I recently purchased a Zen X-Fi2 64gb. I'd been waiting for a player of this size for a few years now but Creative was behind the power curve so I temporarily switched to an Archos 80gb. After the Archos began to annoy me I ended up just going with the Zen 32gb flash based player. It works/ed great. This new Zen X-Fi2 however is unbearably slow! I don't mind quite sometime to rebuild the library once the initial sync is done but when it takes 5 minutes to load a playlist (3000+ songs) then I get upset. It takes so long to load said playlist that the player shuts off before it has time to load all the songs. I can't even just click play right away like I could on the Zen. The only way I've been able to get around it is to tap the screen twice. Once to load the playlist (which takes forever if it's more than 00 songs) and again to play once the lengthy loading process is over with. However even then it doesn't load all the songs. I've been communicating with tech support about this with no resolution in sight. All they keep telling me is how 'normal' it is for a player to load a large number of songs. My Zen which is an MTP player syncs and plays music much faster! Is there anyway to possibly upgrade this to an MTP player?

Hi Vokivolli,
Almost 2 months on from your original post I see that you have received no reply from an administrator. Are these problems still persisting with your player? I have an X-Fi Style too and am experiencing the same problems. Like you I was hoping that firmware updates would address the problem. I don't think that the Style is a priority for Creative and unfortunately I don't see them bothering to solve these issues. Hope I'm wrong cos otherwise I love the X-Fi Style.

See if that made a difference.

IPhone 6 and 6 plus camera extremely slow when using flash

I have noticed that the iPhone 6 and 6 plus camera is extremely slow when using flash, it is definitely slower than iPhones 5 and 5s.
Any explanation/solution for this?

I Have done some more testing and it seems turning off HDR resolves the issue

YouTube extremely slow when accessed using WiFi

I find that, in the last day or so, accessing YouTube has become painfully slow when using WiFi. It was working fine earlier in the week.
EDGE connections have faster downloads but the quality is really poor.
Anyone with similar problems? Any explanations as to what might be causing this?
Thanks,
Anil

Bump to this, I am also experience the same issues as well with Youtube being slow on WiFi compared to the horrific version on EDGE. I would think this to be a Router issue, but I have yet to test it out by shutting down all other applications that access the router as well as other computers that use the router.

Wifi extremely slow after Windows 10 Upgrade

After upgrading to Windows 10 my wifi connection is extremely slow. I updated all the Lenovo drivers after the upgrade and it hasn't helped. The listed network driver is 2x2 11b/g/n Wireless LAN M.2 Adapter. I've included screenshot below of a speedtest on the same network between my T440s and my smartphone. The smartphone results are what should be expected on the laptop. T440s Speed Test Samsung S6 Speed Test When observing the task manager there are no other programs utilizing the network.

I had the same problem.
After trying many suggestions on the internet I found one that solved my problem. I took more than a week to solve but now I'm happy.
On my case the problem was the security wifi protocol. I was using AES and changed to TKIP. For me there is no reason to this to work, but solved my problem.
Hope it helps.

Processing speed of my MacBook is extremely slow when opening applications, whether Mail, Safari or MSOffice

Problem description:
The processing speed of any function is extremely slow - such as opening Mail, Safari, clicking on a page within Safari, switching to MS Word, adding a window in Safari, loading a page from Safari. I get the spinning wheel most of the time before the action is completed. All other Macs which are newer in my home WiFi network operate just fine. I have done a top level (novice) check for malware, and haven’t found anything. Any help you can suggest would be truly appreciated! Thank you!

Before you do anything do you have a current backup? If not make one.
I don't see any of the usual software suspects associated with slow downs. You don't need the Seagate software, you should uninstall that.
Reset the SMC Intel-based Macs: Resetting the System Management Controller (SMC) - Apple Support and PRAM How to Reset NVRAM on your Mac - Apple Support
You only have 2GB of ram and could upgrade to 8GB, but Snow Leopard should run ok in 2GB.....not great but ok.
Start up in Safe Mode OS X: What is Safe Boot, Safe Mode? - Apple Support be paitient as it will take awhile to start as it checks and tries to repair any problems with the file system. Once it's completely started up you can restart normally.
Insert your Snow Leopard disc and restart while holding the C key. Run Disk Utility to repair the hard drive and permissions. While in Disk Utility check the SMART status of the hard drive, anything other than Verified indicates a problem with the hard drive.
Again, you only have 2GB of ram.....try restarting your Macbook every day.....it's been running for almost a week now.

Extremely Slow when Opening a new tab

I have just bought my new Retina MacBook Pro after my 3 years Macbook Pro 13" is total lost and get the Mountain Lion OSX with latest 10.8.2 version
After migrating the MacOSX from Snow Leopard to Mountain Lion, my Mac is everything ok but without Safari.
Once I wanna open a webpage from bookmarks bar, I usually open a new tab then click one of webpage in one of the bookmarks bar. The problem was happened in this action.
After I opening a new tab which I have set to show top site rather than History (all top site are locked like a set of bookmarks), the system extremely slow down even I just move my mouse from one bookmark to another on the bookmarks bar, it still have a bit serious delay more than a second.
I have just tested, if i choose history not top site is shown when I am opening a new tab, the performance really better. However, when I scroll to somewhere all have thumbnails for those webpages, the performance still slow down but not yet as serious as the top site and I think becasue I have choose over 12 webpages for topsite (which are all have thumbnails).
My new Retina MacBook Pro is the lower default spec i7 2.3GHz and the version now is MacOSX 10.8.2 with Safari 6.0.1
one of place I want to mentioned is my Safari and Safari Webpage Content are over 500MB once I have opened. Is it common and normal? I feel really upset that my new Mac doesn't really faster than before but the older one is Core 2 duo and 4GB ram vs the new one is i7 2.3GHz and 8GB ram....oh my god

Try clearing history and the cache...
From your Safari menu bar click Safari > Reset Safari
Select: Clear History (also empties the cache)
Deselect the remaning boxes then click Reset.

WiFI extremely slow in Arch

I have a new install of Arch after deciding to give it a go after 6 or 7 years on Gentoo.
The only problem I am experiencing is extremely slow internet. 1.58Mbps vs 31Mbps previously in Gentoo.
Google seems to indicate a lot of people have similar issues with Arch, but having followed the Wiki to the letter and not finding any solutions on Google I am stuck at where to start.

If you are using a USB WiFi device that can potentially change names with different ports, it would probably make sense to either create a persistent name for that particular piece of hardware, or go back to the old naming scheme if you don't have another wireless card. The idea of these crazy names is that if you have two wireless cards, two ethernet cards, or even an ethernet card and a broadcom wireless card (which also uses the eth* namespace), you will never know which will be 0 and which will be 1. But if you tell the system what to name them, then you can at least have your netctl service run on a given interface name and know what it is going to be.
Having said all that, you should also be aware that other network management solutions deal with changing interface names much better then netctl. Netctl needs the interface name to be specified in the profile, so if it changes you are kind sh*t out of luck until you make the manual changes necessary.
To see if you have multiple network management services trying to handle things, run "systemctl --type=service" to see all the services you have going. If you see more than one that should be handling the network (for example, if you enabled [email protected] during setup) then you need to figure out which single management solution is going to best fit your use case and go with that one only. Most commonly, people still ahve dhcpcd.service or dhcpcd@<interface>.service around. But it is also not uncommon to see people with netctl-ifplugd@<interface>.service running along with netctl-auto@<interface> at the same time, which will also cause issues.

Yoga 2 Pro - extremely slow when plugged to an external monitor with Windows 10

Hi! Like most of you, I was eager to take the step early and try Windows 10 (knowing the risk of running into some problems on the way). Everything works very smoothly, and Win10 is really delightful. The only major problem I've faced is that when I plug an external monitor, every action (launching Firefox for example) takes ages and many apps "doesn't respond". I've downloaded and installed all the drivers for Win10 (included the one for the graphic card). Any idea what is happening or what I could try? Best,François

Hi. I am suffering the exact same thing. But i think i narrowed down the issue:When i am not using an external monitor - everything works nicely.When I am using an external monitor (and laptop set to "Extend" mode) while laptop screen is open - everything works nicely.When i am using an external monitor (and laptop set to "Extend" mode) while laptop screen is closed - everything becomes extremely slow and laggy. I wish Lenovo support would provide a solution asap.

Videos are extremely slow when trying to view them

Here is the situation. I have been posting course material for over a year now, and everything had been working fine. Over the last week, any video that I try to view from our iTunes U site is taking at least 5 minutes to play, when I double click on the video I get the loading bar, the videos that are less than 30 minutes long take between 5 - 8 minutes to play, the ones that are over 30 minutes take between 10 - 15 minutes to play. This had never happened before, and the weird thing is that I can go to any other iTunes U site and view videos that are two hours long and it takes less than a minute to play. So I know its not my network bandwidth or I wouldn't be able to view other sites. I use an iMac with a 2.8 GHz Intel Core 2 Duo, 4 GB of Ram, bought specifically for iTunes U administration. I don't know what else to do. Any help or advice will be truly appreciated.

I have also found our iTunes U site extremely slow for the past few weeks. It also took a long, long time to log into Admin. But at least for us, there has been a noticeable change (for the better) in the last few days.
