I am having problems with wireless speed on my Thinkpad E545 laptop.
Right now I have it setting right next to my old Asus, both running the same speed test software (Speakeasy.net). The Asus is showing 13.4 mbps download speed. The Thinkpad is showing .69 mbps. All wireless drivers are up to date as far as I can tell. Any ideas on what is wrong? |

How are they connecting? Both N or G, one or two channels, what bandwidth per channel?
A lot of access points in a "b, g, or n" mixed setup will only perform well in one mode. So if the asus is connecting on G on one channel and doing fine you may need yo downgrade the thinkpad to G(20mhz) vs N(40 or 20) or AC(80mhz). There may be interference not affecting the narrower band. If connecting on two simultaneous channels you can also get worse performance than a single channel in a noisy environment. But first make sure you have the latest or best drivers for your wireless card. Some real duds get released. |

Have you tried plugging the Thinkpad directly into the router then run the test? |

Plugged into the modem, I am getting over 11mbps.
