Low connection speed on 5Ghz wifi

macbook air only connects at 130 M/Bits on a 5Ghz wifi connection, all other devices including pre unibody Macbook connect at 300M/bits ?

Option click on the wireless symbol in the menu bar.
You will be using the channel that the router is configured to use. Your MBA does not determine what channel will be used.

E2000 low connection speeds

I recently "upgraded" my router from a WRT54G to the E2000, and changed my wireless computers to USB-N adapters. At first they were only at 54Mbps but found I had to use WPA2 (I was on WPA) and after making the change, I had anywhere from 107Mbps to 130Mbps connections. (Although these are dual-band adapters, I can't take advantage of 300Mbps because I left the router on 2.4Ghz only since I have some wireless-G only laptops and I understand you can't have the router on 5Ghz because they won't connect.) Anyway, a few days later, when I checked the connect speeds of these wireless-n computers, one was at 5Mbps, another at 20-something. Signal strength is good to the computers as it's always been. Does this router "alter" the speeds "as needed" or something? Any help is greatly appreciated!

Go to Solution.

I just completed setting up my WRT54G with my E2000 and switched the E2000 to 5Ghz band. Now when my computers with dual band capability connects with the E2000 (using a couple of channels in the hundreds, like 129 and something or whatever) I see a connect speed varying anywhere from 140 to 300Mbps, whereas all my 2.4Ghz equipped computers are at 54Mbps. My daughter's computer has wireless-n but only on 2.4Ghz and it originally connected as high as 130Mbps until I switched the E2000 to 5 Ghz so now she's stuck at 54Mbps. I suppose if I had bought the E3000 (?) or another model that also supports both bands simultaneously then she'd have her wireless-n speeds as well as the others that could run on 5Ghz which affords more "open" channels compared to what's available on 2.4Ghz... (didn't want to spend that much money on a wireless-n router since I knew I could still use my WRT54G since selling it would get me almost nothing for it... might as well use it...

Very low connection speed.

Hi, I've waited the 10 days since I first got BT Broadband and I wondered about the slow speed I am getting. The speed test says my line is rated for 8mbit (8000kbit) but I only get up to 900kbit connection speed, it was around 600-700kbit for a while but now seems to have settled at 900~kbit. When I ordered the package the line check said I can get between 8 and 15megabit but should expect 8.5.
Is there a fault on the line? The online speed checker thing (which seems to have been replaced or I just can't find it anymore) said I should report a fault and that on my line I should be connecting at more like 6000kbit-7000kbit.

Low Connection Speeds

Hi.
After being with BT for not much longer than a month, our HomeHub 3 would just drop connection every couple of mins making using the internet impossible. After switching filters and cables we got the connection to stay but at a speed of 0.18mbps. Even after speaking to BT on the telephone we achieved nothing and they just said it was the filters even though we were using the ones they sent us that very same day

we are connected to the only socket in the house with the filters.
Im not sure what to look for on the log but here is some of what i see on screen

CHANGE DEFAULT NAME/SECURITY SETTINGS = LOWER CONNECTION SPEED

I have a Linksys WirelessN Router--If I use the router with all of the default settings I can achieve cable speeds of 300mbps. Fantasically fast!!! As soon as I change the name of the router from "Linksys" to any other name, my speed drops back down to 54mbps. I also changed the security settings to "PSK Personal" and added a personal password so my system wouldn't get "hyjacked." Any thoughts?

Hi… logon to router’s setup page, try changing Radio band to wide 40MHz, wide channel to 9, standard channel to 11, go to advanced wireless settings reduce beacon interval to 50, fragmentation and RTS threshold to 2304, change N Transmission rate to 270MBps…wireless security should be PSK personal, also try upgrading latest firmware on router, check whether it makes any difference or not.

Progressively Slower Connection Speed

Hi,
I'm having some difficulties with my BT Broadband speed. The connection is getting progressively slower. Each time the router recycles I get a lower connection speed.
According to the BT Wholesale checker I should be able to get 6.5-8Mbps but I've never seen > 3Mbps and am currently <2Mbps.

I have a shielded cable connecting the router to the line-box and the line-box has an ADSL filter faceplate which ought to mean I don't need filters anywhere in the house. This was fitted by a BT engineer.
I would be grateful if anybody could make a recommendation as I've tried everything I can think of.
Thanks in advance,

Hi,
I've left the router up for several days now with no decrease in connection speed:
5. ADSL uptime:
7 days, 00:01:00
6. Bandwidth:

I've tried the quiet-line test with a corded phone and get a constant buzz.
The next thing I've tried is to disconnect the ADSL filter faceplate from the line-box and have plugged a different ADSL filter directly into the line-box. The quiet-line test still yields a buzz, albeit slightly quieter.
Now that I've reset the router (turned it off whilst swapping cables around), I now have the following (with a different ADSL filter):

EA2700 Connection Speed Low ( 72.2mbps )

Hi guys , this is my first post , if i do something wrong already apologize , I'm from Brazil , but I found no competent forum to remedy my doubt , so I came up here
I bought a linksys router EA2700 and after many different attempts to configure it, could not get the wireless connection speed exceeds 72.2mbps .
The speed is well lowers the specified in the manufacturer's website, which disappointed me with the device.
I wonder if anyone has gone through this , I hope a connection speed of at least 150 mbps
The updated firmware this latest version available on the site .
I hope someone can help me, thanks
Bruno Santaella
PS : Sorry for my English , I need another exchange program to improve it

Some devices dont' support higher speed connections. You'll need to consult with the Mfr of each device to see what connection rates they support. Various devices only connect at 65Mb, while others may connect at 150Mb or 300Mb depending. Connection rates differ between thruput rates.
There are other factors to take into consideration as well>
Wireless Configurations
What wireless modes are you using?
Try single mode G or N or mixed G and N on 2.4Ghz and single mode N or Mixed on 5Ghz?

Router Placement
Forum User - "Well I feel really dumb. After moving the router away from other electronic devices my speeds are back to normal. Just a heads up for anyone experiencing slow speeds, you might want to move it away from other electronics and see if that helps."
3-6' feet minimum safe distance between devices.
Placement on main level floor and central in the building and WELL ventilated is preferred. Not in basements or closets as building materials, or near by electronics devices could interfere or hinder good signal propagation.

Verizon DSL - High "Speed (down/up)" Low connection rate

Hello -
I am doing this for myin-laws, who live in a semi-rural area. They have Verizon DSL, and have been having very slow connection speeds for the past few months (they have the 1.5-3 Mbps, and are getting between 200-700 kpbs. Sometimes, for a few seconds, it can get as high as 1.1 Mbps, but it never gets to 1.5.
I have tried lots of things. We got a new modem, reset the D-Link router to factory settings, plugged the modem directly into the desktop, rebooted everything, then rebooted again, called Verizon and talked with their overseas people, who said they would have someone look at it.
Everything, no dice. So I'm not sure what to do.
Here's one thing I noticed, however. When I go into the Modem sign in screen, and look at it (It's the Red sign in, not the Blue, on a Westell 6000 DSL modem), they get a very high "Speed (down/up)" level. Something like 1740 down, and 500-something up.
But the actual downloads are nothing like that.
Is that significant to anything?
My other situation is that I am not at their computer now (I am back in the city). When I left their place, I did not know about these boards, and I can't remember any of the other information that is from the modem sign-in. That one piece, however, seemed strange to me (a high "Speed (down/up)" level, but slow reality.
As you think about it, could that lead to any clues or solutions I should look for the next time I go up there?
Thanks for reading this.

The closest proper sync rate that the modem would show for speed would be 1792/448Kbps, which would be the 1.5Mbps provisioning of the 1.5-3Mbps package. Verizon usually configures the speed lower if the line is not capable of holding a full 3Mbps or even an "optimized" flavor of it (which is ~2600kbps down, 640kbps up). Anyways, the next time you get the chance, I'm going to need the following information from their line:
1: What do their modem Transceiver Statistics look like? If running a Westell modem, visit http://192.168.1.1/ , choose System Monitoring, Advanced Monitors and then click Transceiver Statistics. Post up what you see there. For ActionTec modems, check the Status pages of the ActionTec for DSL Stats. The address to ActionTecs are the same.
2: Find out if the slow speeds are taking place all the time, or only during the evening hours
3: Go to http://visualroute.visualware.com on their PC and choose the closest server to them. Let the Java applet load, and when it does it will show you a "Trace" box with your relative's IP address filled in. Press Trace and let it complete. When it completes, move the mouse over the second-last Circle (second from the right) and take down the name of it. If you see "ERX" in the name, please tell me.
If you are prompted for a Username/Password while doing Step 1, try the following:
admin/password
admin/password1
admin/admin
admin/admin1

Aspire Z3-615 can't connect to 5Ghz WIFI

Hello everyone, i'm just curious. I currently have 2 wifi lines, one normal 2.4 and a 5ghz WIFI. However, my computer, the Aspire Z3-615 on windows 8, isn't able to read the 5ghz WIFI. My network adapter is qualcomm atheros ar956x 5ghz. I've been browsing around the forum, and am pretty sure that my adapter is a single channel, which i guess means it can't read 5g :/ My phones are able to connect, so i'm just wondering if there's any way to make it so that the computer can read 5g? Thanks for the help :-)

In the past, I have always just added a USB network adapter to a computer that needs 5 Ghz. If it says b,g,n.......it will only work on 2.4 GHz It must say a,b,g,n in order for it to work on both 2.4 GHz and 5 Ghz. So you have to read the product descriptions carefully and make sure you see "a,b,g,n" http://www.amazon.com/b/ref=dp_bc_5?ie=UTF8&node=13983791

Wifi Ac iMac 2013 showing connection speed 1g/s

Connected over strong-signal Wifi Ac. Network utility shows the link speed to be 1 g/s. Is that 866 M/s rounded? If I switch to the other 2.5 GHz network, the speed indicated drops to 144 M/s. No issue with coverage /signal/hardware. To me it looks like Network Utility is out of date.

Thanks but the reason for mentioning the other network was that Network Utility indicates the connected speed at least for Wifi N. However for Wifi AC, it is indicating a speed i.e. 1 G/s that is well above the spec of 866 M/s. My question is does 1 g/s on NU = 866? Is there another utility that supports Wifi AC?

X120e WiFi Connection Speed - is 802.11n speed possible?

Dear guru!
Could you please tell me what should I do in order to get 802.11n connection speed on my new x120e? The better speed I get is 65Mbs. On T500 I get 300Mbs with the same WiFi access point (so it definitelly depends on notebokk but not the infrastructure).
Thanks in advance,

Check if your router has a Channel Width selection. Mine was defaulted on 20mhz, which yielded crap performance, after changing to 40mhz it works as good as it can on this 1x1 card and connects at 150mbps to the router where before it was 72mbps.

Low broadband speeds, connection keeps dropping

Recently I have seen broadband speeds drop from about 11mb to about 2. this is coupled with the home hub 4 constantly dropping the connection and the orange power light flashing orange.
Bt have been here but claim no problem on the line.
I am starting to think this is related to the latest firmware upgrade. Is there anyway to roll back to test this theory. Or does anyone have any other suggestions.
Thanks
James

welcome to the BT community forum where customers help customers and only BT employees are the forum mods
in order for the forum members to help please can you post the adsl stats from your router you may need to 'show detail' to get all stats (if hub enter 192.168.1.254 in your browser and navigate to adsl or if HH4/5 then go to troubleshooting then logs and you are looking for 2 line together when hub last connected to internet and they will show your connection speed and noise margin or if netgear enter 192.168.0.1). Then run btspeedtester (MAC users may have problems). when first test completes then run diagnostic test and post the results ( do not reset the router).
Lines should look like this
19:11:29, 07 Nov. (2290101.460000) DSL noise margin: 7.00 dB upstream, 6.10 dB downstream
19:11:29, 07 Nov. (2290101.390000) DSL line rate: 448 Kbps upstream, 288 Kbps downstream
are you connected directly via a filter to the NTE5 master or test socket or to somewhere else? Is the master the only phone socket in your home?
Have you tried the quiet line test? - dial 17070 option 2 - should hear nothing - best done with a corded phone. if cordless phone you may hear a 'dull hum' which is normal
Someone may then be able to offer help/assistance/suggestions to your problem

Force macbook air (2012) to use only 5ghz wifi of time capsule?

Hello!
Is it possible to force the macbook to use only the 5 ghz band of the time capsule wifi?
Otherwise it is loosing lots of speed while switching between the 2.4 and 5 ghz.
(There are approx. 20 other hotsports using the 2.4 ghz band around here...)
Thx in advance!

I would suggest that you configure the Time Capsule to provide a separate name for the 5 GHz network, and then "point" your MacBook at that network.
Open Macintosh HD > Applications > Utilitiies > AirPort Utility
Click on the Time Capsule icon
Click Edit
Click the Wireless tab the top of the next window
Click Wireless Options at the bottom of the window
Enter a check mark next to 5 GHz Network Name (this will add "5 GHz" to the name of the network)
Click Save
Click Update
Then, make sure that your Mac is set to connect to the "5GHz" network as a priority
Open System Preferences (gear icon on the dock)
Click WiFi on the left
Click Advanced at the lower right
Make sure your 5 GHz network is at the top of the list. If not, drag it there
Click OK
Click Apply

Low connection speed on 5Ghz wifi
