WLC 2504 - Slow Internet download speed. Just Internet speed.

Khoa Pham — Mon, 05 Jul 2021 09:04:15 GMT

My network is a simple network: 1 Gateway, 1 switch, 1 WLC2504 and 1 AP-3602I

If I wired my laptop to the switch and do speedtest.net, I get 100Mbs down, 100Mbs Up, which is the speed provided by our ISP

If I connect the laptop wirelessly to the AP, and do a Speedtest.net, I get 30-40Mbs down, 100Mbs Up

If I use IPerf to test the connection from the Wireless laptop to a Wired Server, on the same local net, I get 140Mbs Up/Down

At all time, my laptop is connected at 450Mbs, A channel. Only 1 device on the AP, which is my laptop.

You might will ask, but I verified:

- No QoS setup anywhere in the network. WLAN QOS tab is clean.

- I even removed the switch and connected the WLC directly to the gateway. Same results.

Interesting right ? I know.

Please advise.

If I connect the laptop

What do you expect 100Mbps down & 100Mbps up ?

Post "show client detail <mac_address>" output when you have 40Mbps download speed. Also pls attach "show wlan <wlan_ID>" output as well

by the way, If you are getting 100% throughput from your internet provider that is great.

Unfortunately I dont have access to the console at the moment. But this happens with every client. I have tried to create a brand new WLAN and still have the same issue.

Any idea or does anyone out there has the same issue ?

Lars Erik Braatveit — Mon, 19 Jan 2015 08:28:11 GMT

Hi,

I am seeing this exact problem as well. Did you get any solution to this?

A Wireless client connecting to the Internet will see around 30Mbps download and 75Mbps upload.

This is the same for "speedtests" and FTP transfers.

The same client is able to get around 150Mbps download from an FTP server residing on the same local LAN.

A Wired client on the same LAN gets 75Mbps download and 75Mbps Upload.

The Internet connection is a 75/75 line.

I am stumped here. I've looked at MTU and MSS. There is an ASA in front of the ISP which by default sets the MSS to 1380, this applies to both wired and wireless clients.

The WLC is running the latest 8.0.110.0 software.

So many of these types of

George Stefanick — Mon, 19 Jan 2015 18:19:10 GMT

So many of these types of issues are client related. Intel for example had a issue with uAPSD and their 7260 NICs. That impacts throughput ..

http://www.intel.com/support/wireless/wlan/sb/CS-034875.htm

Issue
Intel has identified IOT (interoperability) issues with certain access points that results in reduced Rx data throughput. When exercising uAPSD, the access point stops doing aggregations on the downlink, resulting in reduced Rx data throughput:

11n 20 MHz channel, about 30 Mbps instead of up to 100 Mbps.
11n 40 MHz channel, about 60 Mbps instead of up to 200 Mbps.

When the uAPSD feature is disabled, the power savings are not realized. There is no other impact. The power savings revert to the level of a non-uAPSD-capable access point.

Looks interesting and I will

Lars Erik Braatveit — Mon, 19 Jan 2015 19:11:59 GMT

Looks interesting and I will investigate this further, but gut feeling says that this isn't the problem as I am getting over 100Mbps when connecting to a server on the local LAN, but less when accessing the Internet.

Also my Macbook and my iPhones are running on the 40Mhz channels, so I should at least see more than 30Mbps.

No I still don't have an

Khoa Pham — Mon, 19 Jan 2015 20:40:28 GMT

No I still don't have an answer. Can you upload the test result as Manannalage has asked below ?

Absolutely. I've attached

Lars Erik Braatveit — Mon, 19 Jan 2015 21:19:48 GMT

Absolutely.

I've attached the files. Some information has been removed due to privacy concerns.

Could this be tied to latency?

I am tempted to try Flexconnect to take the WLC out of the equation.

Channel......................

Rasika Nayanajith — Mon, 19 Jan 2015 21:59:22 GMT

Channel.......................................... 64 
.
Current Rate..................................... m22
Supported Rates.................................. 24.0,36.0,48.0,54.0

As per this you can see your client connected on m22, on channel 64. Refer the below MCS data rates. Your client should get data rate should be 350+ (if client support 40MHz channel bonding). Actual throughput typically 40-70% depend on the RF environment, so getting 150Mbps throughput locally seems reasonable.

Have you enabled channel bonding under Wireless ->802.11a/n/ac -> DCA -> channel width -> 40MHz ?

I am tempted to try Flexconnect to take the WLC out of the equation.

If you could do this as a test, it would verify that traffic has to go through 2504 makes this throughput drop ? Good to see what you find

In my case, I enabled Flex

Khoa Pham — Mon, 19 Jan 2015 22:23:15 GMT

In my case, I enabled Flex Connect with local "Flex Connect local switching" option and I had the exact same issue, which is:

Download speed is limited at 30Mbs from the Internet.

Download speed is limited at 140Mbs from the local network.

Hi! Yes, the data rate seems

Lars Erik Braatveit — Tue, 20 Jan 2015 11:01:53 GMT

Hi!

Yes, the data rate seems good since I am getting good throughput to the LAN.

Channel-bonding is enabled on the a/n network and scans verify this.

Good job on testing Flex

Lars Erik Braatveit — Tue, 20 Jan 2015 11:08:47 GMT

Good job on testing Flex Connect.

Just a question? What switch are you running between the WLC and the gateway?

My configuration is as follows

WLC ------ WS-C3560CG-8TC-S ------- WS-C3560CG-8PC-S ------ 2602I

ASA 5505

The link between the WLC and switch is a trunk, as is the link between the switches. Also to the ASA. The 2602 is connected to an access port with the same VLAN as the management interface.

Both switches are running 12.2(55)EX2

I have this exact same

rlaudiano — Wed, 11 Feb 2015 05:38:39 GMT

I have this exact same problem with my 3 x autonomous 3602e/i and desktop/tablet/macbook. I also cannot understand why it is so slow using speedtest.net.

My internet speed is 1gbps so its really disappointing

hiDid you find any solution i

Thaer.Badawi124 — Wed, 11 Feb 2015 22:57:40 GMT

Did you find any solution i am facing the same problem

when i connect my computer throw LAN Cable directly to switch i get full speed up/down

but when i connect via AP so the speed drop down and the connection between computers and server became very very slow .

??????????

1 WLC 2504

4 AP 1700 series

1 Cisco Switch

1 ASA Firewall

windows server 2008

please help ____??????

I was having the same issue,

rdpierce — Thu, 10 Sep 2015 05:24:48 GMT

I was having the same issue, wired had 90Mbps down/6Mbps up and wireless was like 18-21Mbps down/5.5Mbps up.

I checked my adapter settings and found that mixed channel mode was enabled by default. I changed this to the 5.2 MHz channel and now it's running at full speed.

Something to try.
