Slow wireless on a fast internet connection

The user's small office environment has a plenty-fast connection when tested on my laptop with a cable going to their router, where I am getting 36mbps download using speedtest.net.  In contrast, if I run the test via their wireless connection I only get about 1mbps.  This is coming from the wireless connection in their comcast router.  My laptop showed a 'good' or 'excellent' signal strength.  This same laptop always gets fast throughput on fast wireless connections, so I assume it really is a problem there at their office.  They have had the same problems with their wireless devices--which is why they called me to check it out.

Generally speaking, what can cause such speed discrepancies?  More importantly, what can I do to greatly improve their wireless speeds?  Should I disable the wireless connection in their router, and add an access point?  TIA

which device they are using for AP ?
give a try by restricting the AP/router to service 'N' band only and check the difference.

They are not using an AP.  All they have is a comcast router, in a small office with three people.  I was asking how and why there can be such a speed discrepancy, and if I should disable the wireless connection in their router and add an AP.

have you tried resetting router and clear all the settings regarding that connection and then re configuration.

also please try to connect another typical router and check that connection with any other laptop/device instead of office laptops.

I would get Comcast out there.   Something is either not configured correctly or the device is faulty.

Another thing you can try is a good (not cheap) wireless router of your own.

1. Hook up a LAN port on the wireless router to the network.
2. Give the wireless router a static IP on the network.
3. Turn DHCP OFF on the wireless router.

This links into your fast network (I think you said that) and should give you good wireless speed as well. I do this myself very successfully.

802.11a  supported a maximum network bandwidth of 2 Mbps - too slow for most applications.

802.11b IEEE expanded on the original 802.11 standard in July 1999, creating the 802.11b supports bandwidth up to 11 Mbps

In 2002 and 2003, WLAN products supporting a newer standard called 802.11g emerged on the market. 802.11g attempts to combine the best of both 802.11a and 802.11b. 802.11g supports bandwidth up to 54 Mbps

802.11n (also sometimes known as "Wireless N") was designed to improve on 802.11g in the amount of bandwidth supported by utilizing multiple wireless signals and antennas (called MIMO technology) instead of one. Industry standards groups ratified 802.11n in 2009 with specifications providing for up to 300 Mbps

The newest generation of Wi-Fi signaling in popular use, 802.11ac utilizes dual band wireless technology, supporting simultaneous connections on both the 2.4 GHz and 5 GHz Wi-Fi bands. 802.11ac offers backward compatibility to 802.11b/g/n and bandwidth rated up to 1300 Mbps on the 5 GHz band plus up to 450 Mbps on 2.4 GHz.

It's probably no more than interference.

Try setting the router to use a different channel and see if that helps.

@michael-best: Sorry, but everything you just said is wrong.

802.11a supports speeds up to 54Mbps.  With 802.11n enhancements you can reach 450Mbps with channel-bonding.

802.11ac is only supported on the 5GHz band.

Try different wireless channels.  There might be interference from nearby networks or even equipment (like welders).
