WAP121 extremely slow

A client contacted me for assistance with their wireless network. They had just purchased three WAP121 wireless access points and upon setting them up discovered the devices provided extremely slow access to the Internet. They have cable Internet service from Comcast and when attached to Ethernet or an older wireless router, speedtest.net shows download speed of 30Mbps. But when connected to any one of the three WAP121 devices they get less than 1 Mbps down.

Upon reviewing the settings with Cisco tier 1 support nothing seems amiss. The issue persists even when the AP is transported to another site. I am awaiting contact from tier 2.

Anyone else seeing this kind of behavior?

YES! After reviewing this forum, and testing on my own. Update Firmware, and Turn off 'N' - Just broadcast 802.11b/g networks. I have Comcast with two WAP121, and had SAME issues. This fixed it instantly.

Don't know why, and don't care at this point.

Hi, My name is Eric Moyers. I am a Network Support Engineer in the Cisco Small Business Support Center. Thank you for using the Cisco Community Post Forums.

Sorry for the delay in reaching out to you. Are you still having the issue? You mention that you worked with  tier 1 support. What was that case number? I would like to follow-up on that.

With these units being new we want to follow-up on them very closely.

Thanks

I'm having the same problem with 2 brand new devices as well, both at seperate locations...I've gone as far as tier 2 and they couldn't replicate it in their lab so they closed the case! 

Both devices are behind a SonicWall TZ180.  Since it's a live environment I can't pin the SonicWall to try it with defaults.

Below are the results that I sent to Cisco Support

I did quite a bit of testing last night and I discovered that if WPA or WPA2 with AES, I get the following results:

.67 DOWN 16.22 UP

If WPA2 with TKIP, I get the following results:

15.2 DOWN 17.52 UP

If WPA with TKIP, I get the following results:

18.49 DOWN 8.27 UP

No security, I get the following results:

.50 DOWN 16.33 UP

Pinned to factory defaults with ciscosb as the ssid, I get the following results:

.47 DOWN 13.64 UP

On a wired 100MB Link. I get 21.71 Mbps down 17.13Mbps up

I’ve reset the AP to defaults several times and the common denominator is AES!

Very dissapointed in Cisco support on this one...

I was informed the units my client purchased were "seed units" never intended for resale. We returned them for a refund. You should do the same or try a warranty exchange.

New Member

I too am in the same boat. I have called tech support several times, was shipped a new unit, still same poblem as discribed above. Support seems to be at a lost. I contuine to get the run around everytime I call support. This product is a joke.

What type of device is it behind?

Re: WAP121 extremely slow

It is hooked to a Cisco RV-082.

So Cisco shipped my third replacement unit and guess what same issue. I have now decided to start the refund process. My one lingering question is does Cisco have any quality control? Do new items undergo any testing, or does Cisco just test there products on the public at large?

I have 2 case numbers but the last one is 622083535. I sent an email this morning to start the refund process not sure if it has started as I have not heard back yet. I am willing to try a 4th if I can be guaranteed that it will be pre tested before it ships to me and is a fully working unit.

WAP121 extremely slow

Thank you for the quick reply. I have looked at the two cases for your Cisco User ID, 622083535 and 62195998. The main issue as I am Reading the case is that when connected wirelessly to the AP he only gets 10mbps upload and 1mbps download. Is that the extent of it?

Also sorry for asking any questions, that you may have already answered, but I dont see any answers in the case notes.

What type of service do you currently have Cable or DSL or etc?

I see that you have used other AP's with success, what speeds do they get?

What troubleshooting steps did any of the engineers have you go through?

Thanks

Eric

WAP121 extremely slow

Forgot to ask.

What other devices do you have on the network?

Also are you using G/N mixed, N only, etc? What kind of signal are you wanting?

What type of service do you currently have Cable or DSL or etc? 50mbps 10mbps    

I see that you have used other AP's with success, what speeds do they get? 50/10 the full service of the cable provider

What troubleshooting steps did any of the engineers have you go through? remove security, do N only, 20mhz, 40 mhz, he changed several of the numbers on the page, I let him remote in and try stuff.

What other devices do you have on the network? 2 switchs, and about 20 imacs, RV-082 but the wap121 is hooked direct to the RV-082. I even tried setting the rv-082 port to a vlan of 5 (no other device is hooked up on vlan 5) still same issue.

Also are you using G/N mixed, N only, etc? What kind of signal are you wanting? I want to use mixed if I would get a working device.

Thank you for this information. I am pooling this with some more information that I gathered from Aubre' L. Cyriaque. I am now running some testing in my lab here in the support center to see if I can gather anymore information to provide our Level 2 on this issue.

Thank you everyone for your patience's. If anyone would like to contact me directly, just mouse over my picture to the left and it should show my e-mail.

Re: WAP121 extremely slow

I would like to report that I have observed the same problem with two WAP121 units I recomended to a client as part of a new home network installation. The client purchased these new in April 2012. The ISP is Comcast and the router/firewall/switch is a Cisco ASA 5505. I chose this combination to take advantage of the PoE ports available on the security appliance. The access points are running the 1.0.0.3 firmware. I responded to complaints from the client that Internet access was slow. I spent two hours investigating the issue and have determined that the problem has to do with the 802.11n implementation on the device. Performance under 802.11b/g is acceptable. Performance under 802.11b/g/n or native 802.11n is acceptable for uploading, but download speed is consistently below 1MBps using www.speedtest.net. By comparison download speed using 100Base-T was consistently over 16MBps, download speed using 802.11b/g was better than 10MBps in all cases. I performed A-B testing on each access point and captured the results to JPG. I would like to know if Cisco is planning to address this issue? In the meantime I have set the access points to operate in 802.11b/g mode. I don't feel this is an adequate workaround.

Re: WAP121 extremely slow

Thank you for using the Cisco Community Post Forums.

Yes Sir we are looking into this issue. Please ca;; into the support center and open a case for this. Please reference this community post thread and have the agent send me the case number. They will know how to get in touch with me. (we work in the same area.) I can then work with them on this case.

I see you have already done some testing on your systems, please provide that to them as well.

Thanks

Eric,

Any movement on this?  I'm a Cisco Small Business Partner and have a customer who I was going to use WAP121's at but have put the project on hold based on this and some other threads.  I see there have been no new firmware updates as yet, 1.0.0.3 being the only one out there, so I was wondering what progress had been made on a solution?

Thanks...

I have been told that the firmware is almost through the testing and approval process. No firm date as of yet. I am also waiting to see the final release notes to see what is included in the firmware.

Hello Eric,

Any new updates? Was reviewing this AP for some of our smaller offices but am concerned with the issue of the slow access.

New Member

Re: WAP121 extremely slow

Eric,

Any update on the firmware? I'm looking to buy 3 of these for one of my clients. thanks

Re: WAP121 extremely slow

Hi everybode,

also in Austria I have this problem.

Internet cable speed: 30 MBit down, 4 MBit up,

WAP121 speed: 0,7 down, 3,7 up

Seems it only affects the download speed.

And it is no difference if the device runs on PoE or on "normal" power.

But: if you set the radio settings to 802.11 b/g only (no 802.11n), then the download speed increases to 12 MBit.

Seems to be a problem with the 802.11n implementation (not very good, becaus I bought this product because of the combination PoE and 802.11n).

And it is no difference of I connect with the laptop, the mobile or the TV, no adequate 802.11n speed !!

I bought the device this week, so ... the problems are sill here (also firmware 1.0.0.3).

Hi again everybody!

Today I had a cisco support employee remote on my system, for two sessions, 1,5 and 2,5 hours.

Without any result.

The support employee got a test summary from me with an explaination of my network components / topology.

He will discuss this with his "SME" (his wirells specialist).

Lets see ...

The following information was also to his interest: the hw version of the WAP121:

The hardware version of my unit is: WAP121-E-K9V01

Is this the same version like your problem units ?

New Member

WAP121 extremely slow

The units I reported are WAP121-A-K9 V01.

New Member

WAP121 extremely slow

I additionally played a little bit with the WAP121:

I already tested:

•    Using other security, no security -> no difference

•    Using shorter passwords -> no difference

•    Using PoE vs. normal power adapter -> no difference

•    Using DHCP vs. Static IP -> no difference

•    Disabling nealy every function (logging, spanning tree and so on) which is not necessary for WIFI communication -> no difference

•    Using only lower / upper channels, only 20/40 GHz -> no difference

My WAP121 is connected to a cisco SG300, internal network address 10.1.3.x

What other settings beside the factory default are other WAP121 victims using ?

New Member

WAP121 extremely slow

Hi again,

today I got my replacement unit from amazon, the same issues!

Does anybody know a WAP121 owner who has no problems with the 802.11n speed ?

New Member

WAP121 extremely slow

Hi Eric,

my case number is 622818519, the support employee was Stoyan Stoyanov.

Perhaps you can merge your experiences with these of Stoyan.

The replacement unit has the same issues than the original one (details see below).

New Member

WAP121 extremely slow

Now I set up some tests (I cannot believe that so many units should be damaged).

notebook - cable - ap - air - notebook

--> about 10MB Download/second

Tried different settings, all good speed.

Another setting:

notebook - air - ap - cable - sg300 (cisco switch) - NAS

--> also about 10 MB Download/second (this was strange)

Only the speed to the internet ist the problem, so what devices did you all have between your ap / switch and the internet modem?

In my environment there is a cisco pix 501, perhaps this is the problem.

To bypass my pix, I have to make some changes in my environment, which is only possible on weekend, perhaps this one.

Updates will be continued soon ....
