IT explains Wi-Fi problem at SU

The Office of Information Technology needs all students to participate in "cleaning up" the wireless network of virtual clutter.
Michael Eyer, an IT network service technician, said: "If we can 'clean the channels,' we can give everyone a better experience. This is our stumbling block that we have right now. It's getting the word out to everyone."
For students, having Internet consists of simply clicking on the Crusader network option. For IT, getting the Wi-Fi to students is much more complicated.
Eyer explained the effects that co-channel interference can have on the computers and mobile devices of students trying to connect to Crusader.
"[Co-channel interference] causes slowness with your internet. Students could be asked for their username and password several times, and sometimes it just won't work altogether," Eyer said.
Various access points are located throughout the buildings on campus. These access points provide students with the Crusader network. When other devices such as wireless printers are on, they either attempt to connect to SUGuest or the Crusader network without success, or they become their own access points.
Students' computers and devices may try to connect to these access points instead of the Crusader network, which causes big problems in being able to access the Wi-Fi.
"In Smith, one student couldn't get wireless access in his room with his laptop. After going to his room and finding a wireless printer, we turned the Wi-Fi on the printer off, and then he was able to connect to Crusader," Eyer said.
Students across campus are asked to turn the Wi-Fi off on any wireless devices located in the residence halls. Once the wireless "clutter" is out of the way, IT will be able to go in and figure out where on campus Wi-Fi "dead spots" are located.
Without the interference of other wireless devices, IT can locate these dead spots and address the issue. Students working from PCs are also encouraged to update the wireless drivers on these devices at least once per semester.
"It's a good housekeeping thing to do with your computer," Eyer said.
Network Engineer Eric Kurtz added: "If you're having issues updating your wireless drivers, Intel has a great website for doing updates. They'll actually detect what type of card it is if you have an Intel card. For anything else, just go to the manufacturer's site."
In an effort to expand the Wi-Fi experience on campus, IT installed access points in buildings in Liberty Alley on Wednesday, Oct. 23.
"As of October 23, Liberty Alley is covered with Crusader wireless," Eyer said.
As for houses located on University Avenue, Kurtz said, "There will be some sort of coverage by the start of the spring semester in the Avenue houses."
