Each week on EVDOinfo.com (one of 4Ginfo's "sister sites"), we post tips and tricks that help mobile broadband users get the most out of their service and products. This week's tip will also help lots of our 4Ginfo readers, so we're sharing it here, too!

Some 4G modem users have reported performance issues when using their modems in Cradlepoint routers - a drop in signal strength upon inserting the modem, and a slowdown in performance. After doing some testing, our tech support experts were able to identify the problem, and luckily, it's a simple one: we found that in some cases the WiFi signal broadcast by the Cradlepoint router will interfere with the WiMAX signal that the Sprint & CLEAR devices use if they are too close to each other.

Interesting info here...

Any ideas on minimum length of the usb cable necessary to clear the interference? Three meters is a bit long...

While some separation is better than none at all, I would recommend having 118" (almost 10ft) of separation between the router and the 4G WiMax modem for optimal results.
