E900 wireless router- slow download speeds

So I have xfinity internet with download speeds up to 25mbps. But according to the online test I'm getting speeds up to 10. I googled online and found that I could disable the WMM but when I tried that it actually made it worse, which i couldn't find anyone else that said that happened to. I'm using a mac computer, and motorola docsis 3.0 sb6121 modem. I've been trying to do my online work and it's really annoying that my websites are freezing up and taking forever to load. Does anyone have any suggestions?

The 25mbps download speed, is it the actual speed that you are getting wired directly to the modem using the online test? If not, then you need to clear it out from your internet provider.
Is the 10 mbps the speed that you're getting wired or wirelessly connected to the router? If wireless, try connecting your computer directly to the router using an ethernet cable. If both wired and wireless connections are slow, then you may need to upgrade your router's firmware or adjust MTU settings. Use the links below as your guide.

How to change MTU size
Downloading the router's firmware
Upgrading router's firmware
If the slow internet connection is evident only to wireless devices and not on the wired connection, then you need to adjust your router's wireless settings or do the following: change the wireless security to WPA2 personal, adjust wireless channel to lessen interference (usetrial and error to test which channel works for your network environment), place router in an open space, bring electronic devices away from the router, and check the wireless adapter on your computer -make sure that drivers are also up to date. Also remember that if multiple devices are connected to your router and browsing/downloading from the internet at the same time, it will surely lower the speed on every computer.

Time Capsule as router slows download speeds

Hello,
Over the past couple of months I have been having intermittent internet connection issues where my download speeds slow down from 50mbps+ (Comcast) to under 1mbps, per speedtest.net
I assumed it was a Comcast issue and contacted their support several times. They sent a technician over who had the line reset and that seemed to fix the problems, but a couple of days later it was back. Contacting support again, they had me test the speeds connected directly to the modem (Motorola Surfboard SB6141 DOCSIS 3.0). Connected directly to the modem via Ethernet, I reliably get 50mbps+ download speeds, but using my 4th Gen Time Capsule as a wifi router slows the speeds down to under 1mbps.
After doing research on these and other forums and finding people with a similar issue, I ran the gamut of potential solutions: changing DNS servers, changing wifi bands and channels (2.4 and 5ghz, all chanels tested), changing Time Capsule firmware versions (7.6.3, 7.6.1, and 7.6 are the only versions available for my 4th Gen TC).
I eventually tested with an ethernet cable plugged into the Time Capsule and have the same frustrating issue when directly connected to the router, which means the issue is with the Time Capsule functioning as a router but isn't WiFi specific.
Upload speeds are a consistent 10mbps+ wether I'm connected directly to the modem or using the Time Capsule as a router, even when download speeds are slowed to a crawl.
I purchased my Time Capsule 1 year and 2 months ago, so I no longer have AppleCare for this purchase. I am out of troubleshooting ideas and am on the cusp of purchasing a second wifi router if I can't find a way to resolve my issue.
Thanks for your help!

I can make a couple of suggestions..
You will need to install 5.6 utility on at least one computer.. if you don't have it available already.
1. Replace the ethernet patch cable from the modem to the TC.
2. What I want you to do is lock the speed of the TC WAN port to 100mbit full duplex.
This is only on the v5 utility.
Another method of doing the same thing is putting a small switch between the TC and the modem. Fast ethernet type would be best.. that will force the connection down to 100mbit.
You can also test with half duplex but that would indicate a major problem if it worked.
3. Make sure ipv6 is local link only.. there is no way to turn it off.
Having done those things.. I do note the TC lacks diagnostic and control tools in the firmware, to understand the issue. If those steps do not fix it is likely nothing will.
There is something fundamentally wrong in how the TC is handling routing.. maybe IPv6 getting in the way .. ?? Unfortunately there is simply not enough controls.
The fact that ethernet is affected in this way (though I would do the test with wireless off.. and ipv6 off in the computer as well).. there is little other choice but to get another router.
The TC can be relegated to bridged on the new router.. and still function fine for backup and wireless network for your local network.
If you have applecare on a computer it will still cover the TC.. but I think you may have issues proving the problem.. ie if you take it to apple it will work perfectly.. If you read this forum as I have done.. the SB61xx series modems seem to be a common factor. There is nothing wrong if you test to the modem from the computer but the SB Motorola modem and the TC are incompatible in some way.
I would like you to report the difference in gateway..
When you plug a computer directly to the modem..
Can you please do a copy and paste from Network preferences of the ip and gateway values.
ie this stuff.
Then I want you to get the same stuff out of the TC when it connects.
So we can compare the gateway (Router in applespeak) and if they are different.
How to load 5.6 into ML.
1. Download 5.6 for Lion.
http://support.apple.com/kb/DL1482
Click to open the dmg but do not attempt to install the pkg.. it won't work anyway.
2. Download and install unpkg.
http://www.timdoug.com/unpkg/
Run unpkg on the desktop.. it is very simple.. drag the AirPortUtility56.pkg file over to unpkg.. and it will create a new directory of the same name on the desktop.. drill down.. applications utilities .. there lo and behold is Airport utility 5.6 .. drag it to your main utilities directory or just run it from current location.
You cannot uninstall 6.1 (now 6.2 if you updated) so don't try.. and you cannot or should not run them both at the same time.. so just ignore the toyland version.. the plastic hammer.. and start using 5.6.. a real tool.

Wireless Router Dropping download speeds

I have a WRT310N router. Ever since upgrading to Snow Leopard, my wireless download speeds decrease the further I get away from the machine. While my signal indicator is full strength, my speed drops from 16mbps download to just around 1-2mbps. I've upgraded to the latest firmware, turned off any potentially conflicting wireless devices (baby monitor, Wii, etc) and nothing seems to effect. Interestingly, my upload speeds remain uneffected.
Any ideas?

Did you reset the router after upgrading the router's firmware..If not then,reset the router and reconfigure it from the scratch.

E1200 router: very slow download speeds, ok uploady got

I recently set up a new E1200 router to replace my old one. We are having problems with very slow download speeds (often <0.10 Mbps) even while the upload speeds are OK (8-10 Mbps). Our previous download speed over wifi was 10-15 Mbps.
When I first set it up, the download speed was very poor on the initial computer. After fooling around, it was fine. I don't know what I did that made it speed up. However, my wife's computer has had very poor download speeds. After rebooting my computer, the download speed has also dropped bak to <0.10. I was able to stream Hulu on my Wii just fine an hour ago.
What could the problem be?

So we could have this isolated, check how much speed you’re getting straight to the modem so we’ll have some point of comparison that from your internet provider. If through the router, you have struggles with not getting an acceptable value for download speed especially if it only happens with the wireless connection, you can try these: change the wireless channel and the wireless security on the router. If on the router, you have the channel set to auto by default change it to (3,6,9,11), just have to play around with it. Moreover, for the wireless security, select WPA2 Personal. If that doesn’t make any difference, update the firmware of the router, reset and have it reconfigured.

Exceedingly slow download speeds on brand new mbp os lion

Hi,
There seems to be a lot of posted issues with slow download speeds on the MBP. I purchased mine 2 weeks ago (Oct 2011), a 13" core i7. My download speeds are a tiny fraction of what I get with a 10 year old Dell. Reading the posts on this issue, they all seem to be going in circles. I am technically very savvy although new to apple. I did at one point get an acceptable increase in download speeds after manually entering the gateway, subnet and DNS. However two days later download speeds have reduced from 17.8 MB/s to 37kb/s. The right now the Dell is screaming a 702MB download. The MBP slug is telling me it will take 5 hours.
Has anyone ever resolved his issue?

So as mentioned above I tried connecting to the router using a wire instead of wireless..
many sites work fine....but some do not
Example
works fine
Apple.com
gmail.com
does not work fine...the page does not load up and gets stuck in the very beginning....
www.CNN.com
http://www.sportsauthority.com/home/index.jsp
sportauthority has flash embedded on that page....CNN, I do not know...
could it have anything to do with Flash ?

Very slow download speed with intermittent halts

Need some help.
I run Apple os/x latest version and have since yesterday begun to experience constant very slow download speeds.
I have rebooted the router and I have reset it. I have tested with wireless and wired into router. No real change.
The results are below and are pretty consistent no matter when or with what computer I test it with.
This is very frustrating and I would like to know if anyone has experienced this and if there is anything I can do before calling for service.
Thank you in advance.

Slow download speed on my macbook pro compared to windows.

Hello,
When i use my macbook pro to download a file i hit very slow download speeds (50 kb/s tops), compared to fast download speeds in vista using boot camp (300 kb/s tops) and the same when i use my brothers PC.
Anyone know how i can fix this or why it might be happening?
thanks

Common strategies:
* Use ethernet instead of wireless.
* Get a better/upgraded ISP.
* Get a better/upgraded router.
* Get a newer mac.

IPad 2 / Apple TV slower download speed than laptop?

My Apple TV (gen 2) and iPad 2 both have issues with download speeds. Netflix has pretty much become useless on my Apple TV due to the slow download speeds. I'm currently using CableOne for my internet provider and I consistently get ~ 20-25Mbps download speeds on my laptop, but only around 0.75Mbps on the iPad 2.
I use a Linksys WRT64G router and currently have it set to use wireless "G" only, QoS and WMM disabled, WPA Personal Security with AES encryption and the wireless set to channel 1. All these settings were based off other user's findings that have had the same issues and yet I'm still having problems.
Both the iPad and the router have been rebooted without improvements.
Any other suggestions?
Thanks in advance...

wireless is unreliable for the speedtest as it varies depending on home conditions so only way accpeted is by cable. if that also shows a problem then you can take it from there

Sigh slow download speeds iPad

Is anyone having problems with slower download speeds on iPads and if so any suggestions to fix? Also some videos on my laptop, ex: like twitter mobile uploads I'm trying to view, are slow. Come to think of it, some youtube things slow to download on laptop, too, so not the sites' faults.. Is it Verizon's? Why is the download speed erratic to non-exisitent on certain videos with Fios?

The first thing that needs to be checked first is the FiOS connection. Go to http://measurementlab.net/measurement-lab-tools#tool1 and perform a speed test using a computer connected via Ethernet and see if the results match what you should be getting on your connection. Additionally on the iPad, visit testmy.net and perform their download speed test. If you have any additional PCs in the home that can use Wireless, perform a speed test over Wireless using the Measurement Lab address.

Very Slow Download Speed

Hi,
I am experiencing very slow downloading speeds, when I am just normally downloading something in Safari, or downloading a torrent with upto 100 seeders.
The maximum download speed I have seen on my computer is 80kb/s, which is painfully slow for downloading the Adobe trials, when they reach about 1gb.
I have a router, connected to 2 computers, and speedtest.net has told me that my download speed is 1mb/s.
It seems like download speeds are being restricted to 80kb/s, so is there any way to 'unlock' full potential downloading speeds?
Any help much appreciated!
-Ollie

I think you're making the same mistake a lot of people make.
The maximum download speed I have seen on my computer is 80kb/s
Safari reports downloads in kiloBYTES per second, not kilobits, so that 80KB/s translates to about 640 kilobits per second.
downloading the Adobe trials, when they reach about 1gb
Really? 1 gigabit per second? I assume that's a typo.
speedtest.net has told me that my download speed is 1mb/s
therefore your downloads are progressing at about 64% of maximum. That sounds about right - you won't get maximum throughput for every download - it will vary based on server location, network load and more.

Very slow download speeds with ATT U-Verse

Hello,
Experiencing very slow download speeds with Macbook Pro 2011, on Lion, and ATT UVerse Max, which should allow for an avg. 11-12 MBPS speed. Instead, I get a fluctuating 60-370 kbps speed. I am not experiencing this problem on my Windows machines (Laptop running Windows 7 and Desktop on XP), it is only affecting the Macbook pro. I wonder if this issue is a known problem with ATT U-Verse and Macs, I spent hours yesterday with their support online and they couldn't help me, stating that from their side all settings were OK; the first representative from ATT re-booted the router remotely and that seemed to work for about 10 minutes, and then it went back to a crawling speed...
Any suggestions welcome!
Thanks

Do you have QOS enabled in your router? Did you try plugging the win7 laptop directly and check the speed?

I was experiencing slow downloading speeds

I was experiencing slow downloading speeds(13.68Mbps) so I called my ISP. The ISP tech asked me to disconnect the cable from the airport express & plug the cable directly into the iMac. When I ran the speed test again I got 40.34Mbps download speed. The tech said that was proof that the problem was with the Airport Express & not the modem. However, now I do not have WiFi. And now I am only getting an amber light on the Airport Express. Any suggestions on how to have WiFi without slowing downloading speeds? Note: Downloading speeds were good until this last week. Please help!

Hiya
Airport Express model 802.11 Version 7.6.4
Does it have two ethernet ports on it?? or just one?
You suggest that I replace the Airport Express with an Airport Extreme: I do have an Airport Extreme in another room by our TV & Blu Ray to enable Netflix movies. A Mac Store technician set up the wireless system that way in 2010. Can I use 2 Airport Extremes instead?
Yes, that is no problem. I am guessing the Extreme is linking by wireless?? Or do you have ethernet between the Extreme and Express?
I am afraid of suggesting this, but I would consider just swapping the roles.. put the extreme on the modem.. and the express on the TV and bluray player.. and it will probably work fine.
What are speeds like to the Extreme on the TV? Does netflix play properly?
If you shut down the Extreme, does the speed get better on the computer?
Are you suggesting that the modem should be bypassed and the Express should be connected to the Mac by ethernet?
Not exactly.. you should already have an ethernet from modem to the express.. can you plug another ethernet express to the Mac.. assuming your Express has two ethernet and not just one.
"Try manually setting channels and forcing bands with different name." : I do not have any idea of how to do this.
Try the simple alternatives above. We can consider this as well if those don't work.
Do you have someone you could call easily and cheaply to try and sort the problems??
Otherwise buying a new AE is actually probably just as cheap as getting a technician in to look at it. Not that new equipment wrongly setup will work any better than old equipment wrongly setup.. but you have a month of free phone support from apple when you buy it new.

Extremely Slow Download Speeds Compared To Pc

My PC when downloads the same file at 100+ kb/s when my MacBook downloads at maximum of 25-30 kb/s.
How can I speed it up.

I'm getting a slow download speed, what can I do to improve it?
If you are using a firewall or router, be sure that ports 6112, 3724, and 6881 through 6999 are open and forwarded to your computer and only your computer. Refer to your firewall/router's documentation for instructions on opening ports and setting up port forwarding. Also, make sure that no other programs that use bandwidth are running while using the Blizzard Downloader.
Please consult our Slow Download Speeds page for more information:

Very slow download speed on ipad 2

Okay folks I need your help. I have just installed an Airport Extreme (newest model) wirless router and a new Motorola Sufboard modem and my interenet download speed is pretty good on the pc (23-25 Mbps). However, when I run the speed test on my ipad 2 it is pathetic (.14 - .18 Mbps). My iphone 4 is getting about the same download speed as well. I have reset all devices, tried forgetting the network and then signing on again, but nothing helps. What could be causing the slow download speed on the Apple products?

Okay I got it. I went into the Airport Utility and changed the channel selection from automatic to manual and then I changed the channel to something different. There are a lot of house in my neigborhood and I guess the default channel 6 was just way over crowded. Just did another test on my iphone4 and got a download speed of 18.33 Mbps. The ipad2 yielded a new speed of 24.24 Mbps. Much better now. Thanks!

Exceptionally slow download speeds, no answers from company

We upgraded to 75/75 last week. After installing the new router, my husband, who is a network engineer working from home noticed that the download speeds were exceptionally slow, averaging about 1.5 Mbps. Upload speeds were fine. We called customer service last Saturday and were told it was an outage that would be fixed "soon". That was six days ago. Still no fix. He can't work here because the speeds are too slow. While all the customer service reps have been very nice, no one can get us an answer about when, if ever, it will be fixed. Considering calling Comcast. Thoughts? Anyone else having the same issues?

There were some service issues in the northeast today but they were resolved around noonish. Are you still having the problem? This may all be very basic, especially to your network engineer husband, but.... If you're still having the problem, are you getting the slow download speeds via wifi or with a hardwired (Ethernet) connection to your router? What results do you get using the Verizon speedtest: http://my.verizon.com/services/speedtest/ And what results at www.speedtest.net? That additional info may help a fellow user here on the forum suggest where the problem lies and what you might do about it.
