Wireless Connectivity continues to drop

Afternoon gents.   One of our clients has a satellite office that has been experiencing severe drops in wireless connectivity.  I am going to be going out to the location to troubleshoot the connectivity.   The drops are not happening during tunnel connections they are just in general.   Currently I am told all the equipment is under a desk including the device giving out wireless access.   I was given the equipment they have which is included in this thread.   Has anyone seen this combination of equipment together ever and seen wireless drops happen?
I currently have no remote access to any of this equipment and will not be able to troubleshoot it until I am onsite but I wanted to see if I could get a jump on things and reach out to you for some assistance perhaps you may have seen this setup before and may know where the wireless drops are happening.   This is especially happening on one HP Laptop that I have fully reformatted, installed the latest drivers on including HP Support drivers for the NICS firmware yadda yadda.    They need this to be stable as they tunnel to their other office which has a WatchGuard firewall in place.  

Here is what they have from what has been explained to me.   I am unsure if firmware can be flashed? Or does the modem or firewall whichever is giving out wireless access need to be put on a desk and not under a table?  


Here is the kicker, they will have a laptop on the desk right on top of where all this equipment is located under the desk and the connection still drops.   We're talking less than 1/2 a foot away.  There are typically a MAX of 3 connections sometimes only 1 person at the location and the connection still drops with only 1 unit connected.  

Modem UBEE DDW 36C1 (I am assuming there is wireless on this.)
Switch Netgear FS728TP
Firewall Cisco ASA 5506-X (Not sure if this supports wireless).

This is as much information as I was given I hope this is enough if you need more let me know.  
As always your assistance is always appreciated.

We do not do this. We put Wireless Access points on shelves higher up plainly visible to most computers.

I am unsure if firmware can be flashed?  

Firmware for Wireless Routers and Access Points can be updated. Vendor supplies firmware updates.  Computer wireless cards normally just need up to date drivers.

I can move the equipment to the top of a desk and see if that fixes it.   I hope that's the only cause.   However I do not know what equipment is giving out the wireless the modem or the ASA.

You need to look at the specs of both and see which or both have wireless antennas. Turn wireless off on the ASA if, indeed, it has wireless.

Yeah once I get onsite and can see with my own 2 eyes what the setup is it will be easier I am troubleshooting something I haven't ever seen.  Can that model of ASA give out wireless?
JohnBusiness Consultant (Owner)Commented:
I don't know from here. You need to look at the box / specs when you get there. I don't think so.
Andrew N. KowtaloSupport Center EngineerAuthor Commented:
Yeah most definitely will.   I just cant believe wireless would drop even if the box is under the desk on a laptop being that close to the device.

By "drop" do you mean:

a) Connections are unexpectedly dropping, or
b) The throughput is being greatly reduced?
Andrew N. KowtaloSupport Center EngineerAuthor Commented:
@Dr. Klahn A.  Connections are unexpectedly dropping.

This situation is broadly similar to a recent one with unexpected disconnects.

Check your server logs or sniff the WiFi to see if someone has decided to attack your network with a deauthorizer.

The hard part is this equipment was installed and managed by someone else not us so I think my ability will be limited.   I will keep you posted once we go out there and do a site survey.
