Video streaming with appleTV wifi requirements?

I'm wondering if my Internett is fast enough to videostream from Mac to appleTV. At a speedtest with my phone i got 65 ping, 3,73 mbps download and 0,53 upload. At Apples website it says that you need 802.11g or 802.11n, but how do i check what i got?

Internet connectivity has absolutely nothing to do with streaming from a computer to the ATV.

Look up the information for your router online.

Wifi devices showing my SSID 3 times.

Hello. First off, let me say I am new here and have only some experience setting up wifi, etc. I apologize in advance if this question has been asked before or is something simple I've overlooked. Wireless devices are showing 3 SSIDs. I am using 2 airport extremes. I purchased this newer model in March or so (MD031LL/A 802.11 A/B/G/N Model No. A1408 with simultaneous dual band 802.11n "and twice the range of 802.11g." I previously had the MB053LL/A (Model NO. A1143) 802.11n also.
I had been running the new model fine, not completely certain all of my settings were optimal, but no major issues, except the 2nd floor of my house had problems dropping out at times, and I have, like many people now, a wireless printer, ipad, iphone, appleTV, wifi bluray, TV, and one MacBook Air (1.7 ghz mid 2011) and a Macbook Pro. After some slowing which may or may not have been related to upgrading to Lion, I bought the new AE and things seemed to improve, or maybe the settings were just new, I don't know. Lion also had several updates. I ramble, I apologize.
So I decided rather than selling the old airport extreme, I was told I could use it to extend my network. So I placed it on the 2nd floor and set it up to extend my network. Things seemed okay, and the new AE had 2 SSIDs, 'orange 02 and orange 02 5ghz'. I don't understand how this works, or which I should be connecting to, but again I digress. I need to read up on this. So I had to setup my bluray for wifi and it listed 3 networks (2 'orange 02' and 1 'orange 02 5ghz)
If I go to the 2nd floor there is still a corner that is a dead spot where nobody can get wifi, but luckily we don't go in that area often. But computers on the 2nd floor seem to lose the internet connection randomly (wifi bar shows it is connected) and so I reconnect to a different SSID, 5ghz usually. Or sometimes it's the otherway around. Right now, since our central air decided to stop working in 95F heat, we are downstairs, closest to the new AE and all using the orange o2 5ghz. (see screenshots below)
What am I doing wrong? Why is it showing this extra SSID, how do I know what to connect to and is it possible my settings are not right? My apologies for rambling and perhaps not using the right questions or researching this more on my own, but I did google this and it linked me to a question (unrelated) on apple support dicussions. If anyone has any answers or insight, please reply. I want to learn. I can provide screen shots or whatever info you need. Or perhaps I'm not able to use the older Airport Extreme as a way to extend the network. I also am very confused about the whole 5ghz, etc. When looking at other wifi networks around me, I do not see any others listing as duplicates.
Thank you,
Izaq (Davin) (please be kind, this is my first post)
p.s. screen shots below
also, current speedtest.net (connecting at a nearby server) showed 11ms ping, 35.97 Mbps download and 6.48 Mbps upload. (not sure how that ranks for the amount of devices I have)
and this screen shot from Wifi Explorer:

Wireless devices are showing 3 SSIDs
The new AirPort Extreme is broadcasting two bands... one 2.4 GHz and the other at 5 GHz using the same wireless network name, or SSID, so that is where 2 SSIDs are visible.
Wireless devices will automatically connect to the best signal quality from either band depending on their capabilties. An iPhone, for example can only connect at 2.4 GHz. A newer laptop can connect at either 2.4 GHz or 5 GHz, so it will pick the best signal...automatically.
The third SSID is from the other AirPort Extreme that is extending the signal from the first. This is an older single band device, so it can only extend one band. If this device were dual band, you would see 4 SSIDs.
The AirPort Extreme upstairs is automatically extending the strongest signal that it receives, which is likely the 2.4 GHz band since these lower frequencies are stronger than the higher frequency 5 GHz signals.
Everything appears to be normal according to the information in your post.

Home Hub 3 WiFi - poor connection even when 2 metr...

My Home Hub 3's WiFi has always been **bleep** but lately it seems to be getting worse. Most of my devices are connected via Ethernet and are fine but my WiFi devices suffer problems: poor speeds, high/fluctuating pings, web pages slow to load.
Laptop (WiFi):
Speed test = 31 ms ping, 4.6 Mbps down, 7.0 Mbps up Google.co.uk ping = 27 ms, 48 ms, 301 ms, 14 ms
Server (Ethernet):
Speed test = 10 ms ping, 64.4 Mbps down, 16.3 Mbps up Google.co.uk ping = 8 ms, 8 ms, 8 ms, 8 ms
My server is actually busy doing networking stuff during this, yet has an excellent connection. The laptop's connection is pitiful, with pings all over the place (presumably due to constantly dropping packets). I actually managed to fix this last night by switching from 801.11b/g to 801.11b/g/n on the Home Hub but that didn't last since I'm having the same issues today. I've tried choosing automatic WiFi channel and switching manually to the least busy channel (1/6/11), and I've tried changing from 20 Mhz to 40 Mhz. Neither has any effect. I've also tried rebooting the router, which doesn't help.
I know it's a problem with the Home Hub since it happens with both of my phones also. Plus it occasionally seems to work fine. Is it just dying? I haven't ever moved it from its current position, which is in the centre of my flat.

up to you but using any of the other available channels does help in the majority of cases

Recently in Windows 7 (BootCamp), the internet connection got slower.

I've been using Boot Camp for months then all of a sudden my internet (only in boot camp) got way slower than it should be.
Using Speedtest.net, I get 120ping~, 7Mbps download speed and 1.3~ upload speed. While in contrast on the Mac OS, 14 ping, 23.79 Mbps and 4.22 Mbps upload speed.

It is still a modem/router or configuration issue.
I don't see how just posting numbers though tells the story or why. Not enough to go by.
I use my cable ISP online forum and have them help, they can usually 'see' the modem, and what is happening.
Take the router out of the picture if possible and connect directly to modem and not using wifi.
For reference I get 30Mb down but 2Mb up and 40ms. Wifi is about half that with higher ping.

My computer is slow on the internet and even stops at times, i have 98mbps to the modem but only 20 mbps and sometimes less on a ping test- what is wrong? i am using a wireless connection do i need to upgrade my wireless modem in the mac?

my computer is very slow I have 98mbps to the modem but when i run a ping test on the machine i get 20 mbps and sometimes it is .10 mbps- do i need to upgrade my wireless modem on the machine? what can i do?

used speed test and got 20 mbps, tested the modem and got the 98mbps...something weird as my system just stops and will not load to sites like google and yahoo but will always respond to sites like CNN...does this mean anything?

2011 MBP Ticking & pinging noise

Hello,
My early 2011 MBP is making an incredibly annoying ticking / pinging noise. It comes from the bottom of the case, even when the computer is off. It is completely random but I can seem to produce it if I lightly tap or press on the bottom of the case around the edges.
I brought back the first laptop I had to Apple because of this noise. They replaced the logic board and processor. When I got it back it was still doing it. The manager of the Apple store swapped the laptop for a brand new one. The new one did not make the noise at first, but then after a few days it started doing it.
I tried removing all the screws, and then putting them back in a star pattern and tighetning them down. The noise gets better (doesn't do it as much) but will still randomly make the sound.
I have removed the hard drive and RAM and the MBP still makes the noise. And as I said, I know this is something in the case because it makes the noise when the laptop is completely powered off.
Any suggestions?
Thanks

There is a connector that is part of the RF sheilding that causes this.

Ping and sproing sounds come from my MBP and my MP

lately i seem to be getting a periodic sproing and a ping (i think it is the glass sound).
the sproing seems to come from both my macbookpro and my macpro and the ping comes from my macpro. is there a way to track these down beyond going through each individual piece of software? i'm using postbox and deja vu and i am assuming postbox is one of the culprits even though i see no action on the taskbar.
thanks for any help.

I should check the preferences for each of those applications and see if there's a checkbox for using system sounds.
Also check System Preferences>Sound>sound Effects and see if the option for playing user interface sounds has become enabled. Also check what alert sound is selected; could be one of them is telling you that an action can't be done.

New MBP - wireless/internet access networking problem - a summary!

Greetings!
New MBP here, with all the trimmings (MacOS X 10.4.10 - Safari 3 Beta). New also to the Apple/MAC world
MBP >> wireless networking into a Linksys WRT54G router and >> thru HughesNet DW7000 Satellite Internet connection (not the fastest, but hey, the US and especially rural areas are NOT S. Korea when it comes to speedy internet connections!
Frankly, I bought into it for two reasons: First, hearing about the vaunted Mac a/v/ and doc/photo editing capabilities,... and about MacOS stability, etc... Well, it all needs a little work still: on the part of new users like me, but also probably on the part of the Apple/Mac people as well. 2nd reason I decided to purchase the MBP - i.e. ability to run Windows (I have not yet tried BootCanp, etc...: still resolving preliminary issues!). I still live in a heavy Win environment at my business - no other way of course!
Communications issues seem to still prevail: I am hanging out at several VERY HELPFUL forums (AppleDiscussionForum, MacRumorsForums, etc...) and the same issues keep popping up. Im my case, same as all above reported, with a few additional points, as follows:
1. Xmission errors: seem to be - at least in my case - a constant factor, regardless on how close/far i am from my wireless router. For example, I would be attempting to dwnload an upgrade (large)QT or MacOS file. i am barely into the dowmoad, and I already have several Read/Send errors. By the end of the download, I will have probably about 15 Rcv and 5 Send errors. Never gets quite that bad in my Win machines, I must mention. Anything to do here (I know, there are such things always affecting wireless com). AND, MOST importantly, how that this affect the effectiveness of the upgrade (I spotted same thing with MacOS 10.4.10 and Safari Beta 3 upgrade downloads!). Would it be likely that applying upgrades in such circumstances would screw up the OS??? Could OTOH such errors be automatically "compensated" by re-xmits from the source, and eventually the download would be OK? Because quite frankly, I do NOT know if my important upgrade download was OK to apply to the system, given those errors!!!
Also same thing with PING errors. Quite frequent when pinging another device on my network.
2. Quite often, accessing a site will proceed somehow OK, and then things will get stuck twd the end, as if some buffer somewhere gets overloaded??? Of course, as elsewhere reported, same can often happen with com getting stuck right over the "www" part of the URL!
3. AND, of course, the often reported "NO connection to the Internet", but computer shows good signal level and connection otherwise.
4. Strangely enough, seems that the Airport Extreme wifi card sort of "warms up the the internet" as one proceeds to start using it. It eventually picks up on a network, and often "improves" its connection over time!
5. Built in Airport Extreme seems to not exhibit up all immediately surrounding networks. Sensitivity issue?? iStumbler does.
6. iStumbler permanently posts noise level of 9% regardless of how close to my wireless router/broadband modem I am. Anyone uses iStumbler to monitor network traffic?
This is getting longuish: I just want to get over all those p*ant issues and get into putting my a/v stuff together!!

Thanks for just reading all this!. I am not sure it is all fixable (back to the Win "features" terminology, really meaning "bugs"??)

Thanks, BDaqua. This support forum is quite well stocked: I have been perusing all its nooks and cranies!
On the www.dslreports.com - All things Mac - forum, I spotted a couple of mentions of the following type of infromation:
link: »www.hardmac.com/news/2007-07-27/#7039
- The first TechNote provides information concerning the Airport problem affecting the MBP Santa Rosa (but also other Mac Intel). When used on battery, the wireless connection drops and one can even experience kernel panic. Apple Centers are asked not to exchange affected notebook as this is due to a unidentified bug in the Atheros driver, and should be fixed in the future with a simple Airport system update. So for the moment, unfortunate users are asked to directly power their notebook when using wireless network, or using Ethernet connection when running on battery... in other words, turn your notebook into a desktop
to forum · permalink
I am wondering if you and folks on this close-to-Apple forum know anything about this. At least, we could just await remedy instead of messing around endlessly looking for solutions and... pondering as to whether it was a wise thing to purchase an expensive machine which happens to have trouble communicating online. After all, seems that the Mac folks are prone to spend MORE time online uploading/downloading music and videos instead of my being normally doing with the rest of my (Win) computers, i.e. work on customer lists, correspondence, inventories, accounting, data bases, etc....
So, seems to me we do have a pb and Apple might just save a few $$$ on silly ads and get to work on com instead. if nothing else to avoid the appearance of further - admittedly rather funny - ad-spoofs!
So back to your further inquiry. I run a wireless network from a HughesNet satellite modem, thru a Linksys WRT54GL wireless router, into some nearby office LANed desktops and point of sale equipment, to another neighbouring facility via wireless bridge, and to my Mac laptop. Distance from the laptop to the router: 50 ft max.
It all works surprizingly very well: up to 200kbps up and 1000 kbps down (in prime time, 150 up and 600 down). OK, my set up looks complex and incurring LOTS of activity. Actually, online activity is quite minimal and well scheduled - right now I am the only machine on the network online. Otherwise, our office processes online money wiring for customers among other things.
I'll try your DNS server choice on the Mac settings first. Will report accordingly.
Thanks for everything!

New MBP -- Wireless Connectivity Inconsistent (Despite MBP's Claims)

Have a new MBP, running 10.5.6 straight out of the box. All essential system updates have been downloaded and installed (one FCE update remains undownloaded). The Airport connection is tenuous -- it will stay connected to the internet for hours at a time, and then go out repeatedly. Every time it goes out, diagnostics claim it is connected, as does the Network dialogue in System Preferences, even when it is impossible to load any web page (or complete system update downloads!).
A few things:
1. At no point does the MBP indicate that it has lost a connection to the wireless network.
2. While internet connection is lost on MBP, I am still able to connect wirelessly with my Powerbook, implying that internet connection/router/ISP is not to blame.
3. I tried entering IP information manually, but to no avail. On a lark, I switched the IP address of the MBP with the PB, but PB continued to be able to connect to internet while MBP struggled.
4. While internet connection via my secure wireless network is lost on MBP, I am able to connect MBP to a nearby unsecured wireless network (presumably a neighbor's). I have purposely not maintained connection to this wireless network for long stretches (though I'm using it now to compose this query), so I don't know that the connectivity issues are absent when connected to it, but I have not experienced any inconsistency when connected to it, even in phases when I am experiencing inconsistency with my secure network.
5. My network is secured by way of a WEP 128-bit hexadecimal password. However, the settings under Network in System Preferences insist on calling it a WEP password, no matter how many times I change it to WEP 128 hex.
6. On a couple of occasions, when experiencing proper connectivity on my secure network, I have tried locking the Network settings in System Preferences. Paradoxically, doing this seems to immediately disconnect me from the internet.
That's all I can think of for now. This problem seems not unrelated to some other problems described in messageboards across the web, but I didn't see anyone outline the problem in the exact way that I've experienced it (nor have I seen a sure-fire solution posted to the problems I have read about).

Folks: *there may be a power/signal issue going on here.* I had a similar problem of my network connection dragging to practically nothing when hooking up my LaCie external drive to the USB port. Please see my post below (link and text)
http://discussions.apple.com/thread.jspa?messageID=9914924#9914924
Folks:
Apple needs to get on this issue fast; after turning off my N mode on my WRT160N Linksys Router, I got my packet speed back up to where it should be... HOWEVER I noticed another problem.
When I hooked up my LaCie external drive (connected via USB), my packets on PING practically stall to nothing. I then eject the external USB drive and re-ping and I get acceptable packet speeds; I re-connect the LaCie external drive to the USB port and my PING crawls to nothing.
There is CLEARLY a correlation between the network speed crawling to nothing while hooking up an external drive; possibly a power sink and/or signal interference on the Airport when hooking up a USB device? (or perhaps even Firewire 800 too?)
I sure hope Apple is reading this one, because this could be a MAJOR issue that needs to be fixed ASAP.

My MBP has started to send out TCP packets larger than the MTU on the NIC - is there any place that this can be overriden?

Got a very weird issue here and wondering if anyone has any other ideas. Basically over the wired NIC only, my Mac has started to send out large HTTP/HTTPS packets from the browser (> 1500 bytes) Captures show packet sizes from 2000 all the way to 4000 sometimes. This happens in Firefox and Chrome so doesn't appear to be application related.
This causes fragmentation issues and traffic drops which basically causes most of my websites and tools to crash and burn (and I get all sorts of SSL errors from applications, etc).
It appears to be limited to just TCP packets as pings with the DF bit set will not send any larger than 1500 bytes.
However if I switch to wireless, everything works fine and captures show the correct maximum packet size of 1500 for all packets leaving my client.
The MTU on the en0 interface is 1500 as per ifconfig and I made sure that it was set to 1500 in Network config panel (because there is an option for jumbo frames there which bumps up the MTU).
A packet capture also shows that during the three way handshake the TCP MSS is successfully sent and negotiated as 1480, but then it appears to ignore that when sending packets later in the TCP stream.
I've rebooted, upgraded to 10.7.4, checked the "sysctl" outputs and matched against a Mac not having the issue.
This is the newest MBP 15 inch model.
Any other ideas on things to check?

Have you used any sort of "tuner" software? You are obviously an advanced user. Sometimes we hack things up and forget about it later. If you are sure you didn't do that, maybe poke around with IPv6 settings. Supposedly people are trying to enable that and it is going to be a disaster.

10.7.3 MBP Wifi Problem - Endless Timeouts & Dropped connections

I've been reading around here a bit already and so I know many other people are having Wifi issues with Lion, but given that there are so many discussions and so many pages of talk, it's hard to go through it all, and using the search I haven't found anything that's quite similar to what I'm experiencing, so I'm starting a new topic...
Basically, I've got a late 2006 MacBook Pro, installed 10.7.1 (form 10.6.8) on in back in Aug 2011 and everything seemed to be fine. I updated to 10.7.2 sometime in Jan and still didn't notice any issues, but wasn't using Wifi at all at the time.
Then in Feb I moved and started using wifi (with a Cisco N router), and noticed that often, the system would not automatically reconnect to the network after waking up from sleep. Just selecting the network manually worked on the first try every time though, so it wasn't so bad.
At the end of April, I finally got around to installing the 10.7.3 update. I read it was supposed to fix wifi issues and so was looking forward to it. It installed fine and didn't seem to cause any problems...
2 days later I moved again (to India), and all **** broke loose... Now, I can rarely connect to wifi (a Beetel G router, configed with WPA). Around 25% of the time, the network won't show up in the list (despite being a clear 5ft from the base station), and when it does show up, 95% of the time I get a "connection timeout" error - often immeadiately, but sometimes it takes about 10sec to respond. On the same network, 2 Win 7 Dells and an iPad 1 all work flawlessly - it's not the router...
One the occasions that I am able to connect, it usually works fine, but if I put the computer to sleep and wake up again, there's no guarentee that the connection will work again - it's back to the lottery. And sometimes even when it's connected, the wifi stays (according to the menu indicator) but the internet connection disappears (to the point I can't even ping the router - 100% packet loss, let alone any internet server)
I've tried zapping everything I can think of (PRAM, SMC), repairing permissions, clearing the remembered networks from the System Prefs, deleting old Locations and creating new ones etc. I have a clean install of 10.7.1 that I booted off of, but it still had the same issues!

I'm pretty savy with computers and have dealt with all kinds of stuff before, but this one is beyond me, and is really annoying! I konw my machine is old, but it was totally useable up until these Wifi issues, and now wifi is basically useless.
From what I've read, it seems like its a driver issue with the Atheros card in my machine, but most people seem to be complaining about dropped connections (mine rarely drops) rather than timeout connection issues. I've also never had the "hardware not found" issue that many people have, so I think this is something different.
Anyone out there have any advice? I'm getting close to losing it with wifi since the update!

Sorry - to add:
I don't think it's a question of WPA vs. WPA2, or even channel number - I have 2 identical routers here and neither work (both default to WPA Ch 11) but I changed one to WPA2, new SSID, various channels and still had the same problems.
Another thing to note that should be irrelevant, but who knows: the Firewire controller on my machine died back in Fall 2010 - to the point where the system won't start-up unless I remove the IOFirewire***.kext from /System/Library/Extensions , and as soon as I do that, it works flawlessly (minus Firewire). It meant I had a **** of a time installing Lion becuase I can't boot off the Recovery Partition (which has the drivers baked into it), but by cloneing my HD, installing Lion onto the clone via a borrowed machine, removing the .kext's and cloning back, I got it on and everything seems to be fine otherwise... I posted about that problem before, but never got any answers. And it wasn't just me, my father has a late 2007 MBP and the same firewire issue happened to his within 5 days of mine (not a power spike - I think it was shortly after some system update if I remember correctly).

Packet loss when flood pinging a Mac

I had some trouble transferring large files between my iMac and my MBP the other day and so started a bit of investigation. Mistake really - here is what I found:
All mac targets are running up-to-date Leopard and use intel processors.
The home network has a linksys wireless router - all devices connected by copper.
flood ping tests with command 'sudo ping -f <target>:
from iMac to MBP shows 30% packet loss
from MBP tp iMac shows 33% packet loss
from iMac to windows laptop 0% packet loss
from iMac to linksys router 0% packet loss
from iMac to Freecom NAS box 0% packet loss
from MBP to windows laptop 0% packet loss
from MBP to linksys router 0% packet loss
from MBP to Freecom NAS box 0% packet loss
I took the macbook to work and picked targets on another site, several busy switch hops away.
from MBP to windows desktop 0% packet loss
from MBP to another iMac 26% packet loss
from MBP to mac mini 28% packet loss
from MBP to linux server 0% packet loss
from linux server to MBP 32% packet loss
The firewall is off on all the targets.
Seem clear enough - Mac machines can't handle high ping loads. It is no good telling me they don't have to. If they can answer a ping at all, they should be able to handle the load. It is a perfectly acceptable way of stress testing the link. File transfers are generally not an issue but now I want to know...
Why can't the macs handle the ping floods?
Is this indicative of any other weakness in the IP stack?
Pete

I had a suspicion of packet loss on my internet connection but could not be certain it was the ISP at fault. The fact that I had been having trouble transferring large files between my machines led me to look for possible local problems.
Network fault finding should always examine the hardware first so I wanted to see if there was anything about the cabling or the router which might be causing packet loss.
Actually copying data about the network is a pretty poor way to test things because you have several additional layer of complexity that can colour the results.
When I had narrowed down the flood ping packet loss to the macs, I went hunting on the 'net. There were plenty of people who were reporting various kinds of packet loss. Enough of them that I wondered if there was something more to it. Some of them were talking about similar symptoms to mine. The respondents usually answered a question other than the one asked so I thought I would put up some tests and see if there was actually a problem anywhere.
Now I know it is a 'feature' rather than a fault, I can work around it.
Thanks anyway
Pete

Ongoing crashing and power issues (late 2011 MBP)

Hi everyone,
I'm having some really irritating ongoing issues with my 15" unibody MBP, which I purchased new from Apple in Dec 2011. All okay 'til now apart from a hard drive replacement in May when the other one suddenly died (no reason given).
What's happening is that I will be doing some low key activity - internet etc (not overheating nor fans on) - and it will suddenly switch off in a second, almost like it's short circuited. Nothing like the kind of delayed, slow shut down when running out of battery, just a ping without a 'ping'. It then won't respond to being turned on via power button, the battery lights on the side won't light up, and the magsafe light is also off and not charging. This has happened four times now.
1) First time (late June), I was watching a video on the net, mbp plugged in at wall, at least 80-100% charged. Went to connect my iphone via usb, got as far as plugging the usb (unattached to iphone) and it went off immediately. No response as above to anything. Took it to the Apple store the next day, no response to being plugged in there so they theorised that it was the logic board and took it in overnight. The next day I get a phone call from one of the techies backstage saying he'd gone to plug it in and after about 20 mins it began to charge up fine, albeit completely drained of battery. He said he'd done a hardware test etc and everything appeared fine. So I went to get pick it up, they replaced the magsafe saying that must have been the source.
2) Less than a week later, it happens again, this time nothing attached to the usb, and as far as I know before it shut off, charged/charging in wall. No response for at least a day at home of me trying it in various power outlets etc. Just dead to the world. I take it to the genius bar the next day, they plug it in with one of their chargers and it lights up immediately, once again saying it'd been fully drained of power. Again they do a hardware test in front of me, show me everything is fine. This time they replace the plug end of my charger and send me off.
3) Two weeks later (last Monday 9th), I go in to my room and find it on my desk dead to the world. Plugged in, this time in a different house (so no chance of faulty wiring in walls of first). I can see a dim flickering light in magsafe but not enough to charge it, it seems. Won't respond to my attempts to turn on nor plug in around the house. On Thursday its still unresponsive, so I travel 2 hours on the train to my nearest Apple store, only for it to light up soon as they plug it in at the bar, and once again 0% battery. Guy tells me that it'll be my SMC 'getting confused' because I don't shut it down enough (I mostly let it sleep). He says it starts working again after 2 days because the SMC must be resetting itself somehow in its hibernation (?????). I take it home, start making a conscious effort to shut it down once or twice a day when I know I won't be using it. I also installed the recent OS and firmware updates.
4) Saturday night (tonight 14th). On the internet in bed with phone plugged in via USB, I unplug phone on phone end and it happens again. I can't turn it on, dim green flickering in magsafe, no lights on side of mac.
I honestly can't afford the money nor the time to keep travelling to Exeter only for it to charge soon as I put it down (magic touch of the apple store circuitry/staff I guess).
I can't reset the SMC as it won't turn on either way - I've tried this every time its happened, under the direction of applecare phone support and it doesn't do anything for a dead machine. Along with all the other keyboard combos they suggest. The only thing that 'cures' it is 2 or 3 days of being completely unresponsive, and then spontaneously deciding to charge like nothings happened beyond a battery drain, usually in the store.
What can I do? Whenever I go to the Apple store it works fine and I look like an idiot, plus they checked the hardware (incl the logic board) the first time. Could they have missed something? I spent so much money on this thing, I almost feel like I've been given a dud and they don't believe me enough to replace it.
TIA,
Thomasyn

You've documented your symptoms pretty well - put it in a document and present it to the Apple Store 'genius'. I would insist on a logic board replacement and a battery replacement. I feel as if you have a dud as well (the hard drive dying so soon, the problems you're describing, etc.). Apple will have a log of your AppleCare calls so make them frequently.
Before going back to the store, call AppleCare again with your symptoms so that they can document them. Let them make your appointment at the Apple Store.
Good luck,
Clinton

Infinity 2 up and down speed, very slow, huge ping...

Hello wonderful friendly people, i'm looking for a bit of help to narrow down the cause of the terrible internet connection I have.
I live in a flat in a new build block in Bristol, just moved in with the owner who has had a few different connections with different providers in the last few years but have always been really bad service. He is now paying for Infinity 2 but we experience massively varying internet speed, as low as 0.25 Mb and as high as 20Mb download, but upload seems to be a bit more stable.
Streaming netflix, downloading files and general browsing is somtimes OK, but mostly terribly slow. It seems the speed goes up and down constantly, hitting rock bottom very often. Playing games is an absolute nightmare. Ping as low as 5, then shoots up to 500 meaning we can't play at all.
In short, paying a lot for terrible internet. The connection is through the phone line, we have a Homehub 3 but with an ADSL modem, i'm not sure we should be paying for Infinity if it's going through ADSL though? I thought Infinity was only phone line for the last bridge between house and local cabinet?
I think the problem is with dodgy cabling in the flats. From my experience this is where the problem points to but I want to be sure before I go to BT and ask for them to fix their line problems.
Here are some results from the last few days from speedtest.net
Can anyone help me with tests I can do to find where the problems lie, i.e. ping tests, trace routes and the like?
Cheers!

Download speedachieved during the test was - 3.89 Mbps
For your connection, the acceptable range of speedsis 16 Mbps-77.43 Mbps .
Additional Information:
IP Profile for your line is - 77.43 Mbps
Upload speed achieved during the test was - 6.77Mbps
Additional Information:
Upstream Rate IP profile on your line is - 20 Mbps
Thanks

No ping to my MBP
