Problems with Cisco AP

Good day to all,

I have an access point (Cisco Aironet 1240AG) in the warehouse, this month a huge project started and there is a lot of traffic in the warehouse and I started having problems with the AP.  We do have a strong signal but the internet is really slow and once in a while it drops the connection.  When I do a ping to any website I get fast replies for the most part but I also get timeouts.

I checked everything, cables, antennas, I moved the AP to different places, played with different channels but nothing worked.  So I decided to replace the AP, I got a Cisco WAP4410N and not surprisingly I got exactly the same problem with the new AP.

Hope you can give me a few tips of what to do.

thanks...

Can you install a program like InSSIDer and do a scan to see if there are any other WLANs about?

Portable, direct connect server access

The ATEN CV211 connects a laptop directly to any server allowing you instant access to perform data maintenance and local operations, for quick troubleshooting, updating, service and repair.

Just get InSSIDer Home, should be free.  You just need to scan for a few minutes in the first instance, then post a screenshot.

The signal is quite weak.  I'd be looking for around -67dBm at least in order to maintain a solid connection.

What antennas do you have connected to the AP, and how high is it?

sorry about that i was too far away.  i put the AP back on its original place.  The AP is located in a warehouse and i have it in the ceiling of the warehouse with 2 antennas (2.4Ghz 9dBi)  here is another screenshot you can see the signal is strong but it kept dropping my connection this time:

That's better.

Can you change the channel to 11 and test again?

here are the results for Channel 11, everything looks good but you can see that the connection to the AP still times out.  This happens with all the wireless devices and same result when I switch the AP to a brand new AP.  any ideas??

That just looks like really bad interference to me.  I'd take the AP to a place where there's not much other RF about and test the AP.

Can this interference be prevented by getting an AP with a 5GHz band?

Yes as long as your devices support 5GHz.

What AP do you have?

It turned out to be real bad RF interference from some equipment being used in the warehouse.
