Internet speed problems on different devices

Hi there,


We have TalkTalk Broadband that we've been with since they basically first set up back in 2004 or near then (can't remember) and we've been pleased accept from the customer service which is just awful (hence I'm asking here first).


With that in mind, we was on their 38MB fibre and we got 38MB download on the iMac(s), iPhones and iPad 2 (which is now very old)


We are now on their 76MB download, and are not very impressed - my iMac (2013 model ac WIFI) gets 65MB-69MB, my dads iMac (2011 model) gets 50MB, my iPhone 6 & girlfriends gets 30MB-46MB (these have ac WIFI - and I get 69MB download on 4G so how does that make sense?) and my iPad 2 gets an awful 20MB.

A side note: the PS4 gets 19MB-27MB which it always has done, I would Ethernet this but I cannot, but thats decent for gaming I don't notice anything.



We are using a Airport Time Capsule that we've had since it's release (latest model) and I'm wondering if I should be tweaking anything in the settings for it, I do have 5GHz enabled, it's not conflicting with any other networks. Our devices are in the next rooms from the Airport, so they aren't too far away. I just cannot understand why the iPad 2 has lost speed from upgrading to this package, and the iPhone 6 always had a constant 37MB-38MB and now it's mainly either getting the same or a little better at 47MB - but it's 4G speeds are 69MB? I can't understand.




Hope someone can help, I posted this here as I thought it could be a Airport 'problem' and not TalkTalk, I really don't want to get in contact with them as they are not helpful and end up making you want to break something!

Sorry nothing I type is being accepted.


Yosemite is a problem ..


Did you clean install or upgrade?


I want you to get rid of the iphone working as a hot spot.. that isn't helping.. turn it off.


Did it work ok on Mavericks? Is this problem since upgrading OS?


I cannot post .. I have typed the stuff out 20 times and it is rejected.


Email me direct.. my profile has my email open.

Tracking down the cause of slow wireless can be a huge pain.


I do need to know a few things..


1. When you measure the speed are you ensuring nothing else is using bandwidth?


Wireless is a shared media.. that means all devices on wireless will cause a slow down, whether they use bandwidth or not but clearly you are sharing it with multiple device it must be measured with everything else turn OFF. Not standby.. OFF.


2. What modem do you have supplied by TalkTalk and is it functioning as router? Is it also wireless router? Can you please turn on the talktalk wireless if available and do measurement to that as well.


3. What link speeds do you get on each device and what band are they connecting to? Can you please change the wireless names so you can force the connection to 2.4ghz or 5ghz.. eg name is TC24ghz and TC5ghz .. also you must use WPA2 Personal security.. nothing else is going to give you peak speed. The password should also match name, meaning short, no spaces and pure alphanumeric.. names 10 characters or less.. passwords 8 characters or more.


4. Your computer speeds seem ok.. 65-69Mbps for a 76Mbps connection is what I would expect. You would also expect the older mac to be a bit slower since it has lower end wireless card.. so 50Mbps is ok for that.


5. To get high speed you must join the 5ghz band not 2.4ghz and the poor old ipad 2 might not manage it.


Give me the link speed the wireless actually is joining. eg this is easy in the Mac. This is a bit ancient screenshot but you hold down the option key when you click the wifi symbol.. it then pops up a heap more info.. I need this info.

For your iOS stuff it is less easy.. let me see what you use to get that info.


Fill me in and we can work away from there.

Thank you for the fast reply 🙂 I'll answer them in order:


1. I test the speeds with the exact number of devices on my network. At the time of testing this normally is my iMac + iPhone and iPad. I got these speeds, I also tried an ethernet cable to my iMac to see if it would improve and it did not, I still got the same speed I was getting on Wifi with these devices also connected. I have tried testing my iPhone with nothing connected however, and have got the same speeds.


2. Our Modem is a BT Openreach box that was supplied with our 38mb download internet - it's just a plain white box with no Wifi capabilities. I did unplug the Airport Extreme and plug our supplied TalkTalk Router (that was replaced by our Airport) and actually got worse speeds, so the Airport must be worth it's money! 😝


3. I'm not too sure what you mean about link speeds, so without further explanation I can't really put my finger on this - but, our wireless name is unique, it was Airport Extreme and the 5GHz channel was the same name but with 5GHz in it. I changed these to Airport 2.4_LE & Airport 5.0_LE - as far as i'm aware the password is a WPA 2. It's a random code + letters that was used from a very old router we used to have, only so we can remember it!


4. -------


5. All of my devices are on 5GHz, accept the iPad 2 and PS4 + Smart tele's (the PS4/TV's won't find the 5GHz channel). The iPad can connect to 5GHz but I was led to believe it'd be a waste of time because it doesn't have ac wifi - as I believe to get ac wifi you have to be on 5GHz, it won't happen on 2.4GHz.

As you can see above, this is what I have. You can also see the mac picking up other Wifi Networks, there aren't many as we do live in a spaced out area, the houses aren't too close at all. I remember a good 7 years ago or so, we had a Linksys Cisco that we had no trouble with, we have a very long garden and used to be able to still pick up the wifi down the end of it (was very slow however) - these days I cannot get 100% signal in my bedroom, the router is in the hallway which is walking pace of about 5 steps (hope that is the clearest I could explain that, it's literally not far away). The iMac is fine, but the iPhone/iPad always drops a bar on the wifi symbol (3 to 2) and I cannot understand why - in the spare bathroom I get 1 bar and sometimes a drop out, however there are a lot of walls to get past for the WIFI so I can understand, but at the same time I cannot because how things used to be a long time ago. The PS4 is on 75% signal strength which is right behind me where my iMac is, so again very close to the router with only a wall in the way. I can only think it's now because the neighbours have WIFI, and all the many new signals including 2G/3G/4G which I bet wasn't around back then, and all the GPS signals etc etc. Must be that. We've never really had a good wifi signal since we got rid of that Linksys, since it is very old now and was slowing down (maybe because interference increased over the years, and not what we thought at the time of the router wearing out)



I will also add: on the 38MB download, we did have 1.6MB upload which was awful, on this 76MB download we have 14MB-19MB which is great, but I cannot understand why the download hasn't got anywhere near on other devices except from my iMac. The iPad actually lost speed! Cannot understand it.




Going back to that screenshot I linked, there is an option for DHCP in the router where I can change it from 10.0.1 to 192.168 and there is another one but I cannot remember it by heart, I don't know if these are meant to make a difference.


I wanted to connect using PPoE (I think thats what it is) but I believe TalkTalk only use PPoA so it won't work, I have tried doing it and typing in my ISP username and password but it doesn't want to know, I remember it said the password is wrong (which it isn't) and I hadn't typed in a load of codes I don't know what they are anyway. This isn't going to make a difference by connecting via DHCP?



Thank you!



sorry just to add: the speed test on TalkTalk's website is supplied by Ookla, on my imac it tells me I get 47MB download, but on Ookla's speed test off of TalkTalk's website it tells me I get 67MB - and other speed tests also say the same, so why on TalkTalk's website does it tell me something different?


on my iPhone speed test app which is Ookla, I get 47MB as you know, so does my girlfriends iPhone 6 so I tried other speed tests on the Internet (same ones as iMac) and they also say 47mb. Weird.

Yes, I have replied.


I posted this to see if it would.. seems ok.. as soon as put something it doesn't like into the mix it goes haywire.


BTW to anyone else reading..


Start from a factory reset. No files are lost on the hard disk doing this.

Factory reset universal

Power off the TC.. ie pull the power cord or power off at the wall.. wait 10sec.. hold in the reset button.. be gentle.. power on again still holding in reset.. and keep holding it in for another 10sec. You may need some help as it is hard to both hold in reset and apply power. It will show success by rapidly blinking the front led. Release the reset.. and wait a couple of min for the TC to reset and come back with factory settings. If the front LED doesn’t blink rapidly you missed it and simply try again. The reset is fairly fragile in these.. press it so you feel it just click and no more.. I have seen people bend the lever or even break it. I use a toothpick as tool.

N.B. None of your files on the hard disk of the TC are deleted.. this simply clears out the router settings of the TC.


Setup the TC again.


Then redo the setup from the computer with Yosemite.

1. Use very short names.. NOT APPLE RECOMMENDED names. No spaces and pure alphanumerics.

eg TCgen5 for basestation and and TCwifi wireless name.



If the issue is wireless use TC24ghz and TC5ghz with fixed channels as this also seems to help stop the nonsense. But this can be tried in the second round. ie plan on a first and second round of changes to fix this.. hopefully.. I will point out other steps that can be round2.


2. Use all passwords that also comply with 1. but can be a bit longer. ie 8-20 characters mixed case and numbers.. no non-alphanumerics.


3. If the TC is main router you can skip this point. This is only an issue when the TC is bridged.

Ensure the TC always takes the same IP address.. you will need to do this on the main router using dhcp reservation.. or a bit more complex setup using static IP in the TC. But this is important.. having IP drift all over the place when Yosemite cannot remember its own name for 5 min after a reboot makes for poor networking.


4. Check your share name on the computer is not changing.. make sure it also complies with the above.. short no spaces and pure alphanumeric.. but this change will mess up your TM backup.. so be prepared to do a new full backup. Sorry.. keep this one for second round if you want to avoid a new backup.


5. Mount the TC disk in the computer manually.


In Finder, Go, Connect to server from the top menu,

Type in SMB://192.168.0.254 (or whatever the TC ip is which you have now made static. As a router by default it is 10.0.1.1 and I encourage people to stick with that unless you know what you are doing).


You can use name.. SMB://TCgen5.local where you replace TCgen5 with your TC name.. local is the default domain of the TC and doesn't change.

However names are not so easy as IP address.. nor as reliable. At least not in Yosemite they aren't. The domain can also be an issue if you are not plugged or wireless directly to the TC.


6. Make sure IPv6 is set to link-local only in the computer. For example wireless open the network preferences, wireless and advanced / TCP/IP.. and fix the IPv6. to link-local only. Do the same for ethernet if you use it.





There is a lot more jiggery pokery you can try but the above is a good start.. if you find it still unreliable.. don't be surprised.

You might need to do some more work on the computer itself. eg Reset the PRAM.. has helped some people. Clean install of the OS is also helpful if you upgrade installed.


Tell us how you go.



Someone posted a solution.. See this thread.


Macbook can't find Time Capsule anymore


Start from the bottom and work up.. I have a list of good network practice changes but I have avoided Yosemites bug heaven.



Yosemite has serious DNS bug in the networking application.. here is the lets say more arcane method of fixing it by doing a network transplant from mavericks.

When you get iphones and yosemite together some very strange stuff can start to happen.

Apple is trying to make the computer and the phones talk to each other directly in a peer to peer network that has to do with the hand off stuff.. That is why the DNS was changed I think.. it hasn't been a great success.

Delete all your wifi network names and start over; do two things

1- go into airport utility and uncheck that 5 GHz network

2- name your new wifi network a shortish name with NO spaces in it , you can combine two names if you desire


Then since you've unchecked that 5 GHz network the router will be able to negotiate the FASTEST speed to choose and it will mostly be 5 GHz. It does not choose the most reliable just the fastest. You tx rate will tend much higher.


Do not ignore that simplified wifi name either.


btw once you rename that wifi make sure you check all your Macs, iOS device and ATVs.

Apr 2, 2015 12:24 PM in response to DonH49

I have done this, it's not made much difference. My Tx Rate on my dads 2011 iMac that runs Yosemite also gets Tx Rate of 400 - my iMac 2013 ac wifi gets 87 Tx Rate. After doing all this messing about, including deleting every wifi setting on mac, iPad and iPhone it's made no difference, what it had done though is so far I haven't seen my wifi bar going up and down all the time - so thats one thing.


It's very strange, because I hold options down on the wifi signal to see the Tx Rate, and when I do it's at maybe 300, 400, 500, 700, 800 - even been seeing 1045 THEN it drops straight away to 87 - like it's saying NOPE or something. It's like someone waving a thousand pounds in your face, pulling it away and only giving 87 haha.


LaPastenague has been helping me via email, we figured it might be Yosemite just messing about. I've read up that the next Yosemite update is the 24th of this month, so hopefully that fixes it. A lot of people were complaining about the Wifi also, hoping it will fix it for them. So I can only hope. I've got to complain about Yosemite, it's been pretty buggy and Apple haven't shown much interest in fixing these problems. My iTunes asks for my password for auto downloads 5 times in a row before it actually checks, when my External HDD boots up at startup and wants the password it doesn't display the image of the HDD next to the box like it used to before Yosemite - things like that.


In general also, my dads iMac (That used to be mine!!) works better than this, I always get a feeling when I briefly use it, that the performance of it is just better. My iMac has a faster processor and has that turbo boost which I never notice and I don't think actually works, just a gimmick. Shame.
