frequent WiFi disconnection

Question

frequent WiFi disconnection

My iMac is WiFi internet connected because fo absence of LAN at its site. The router is a D-Link N300 DSL-2750B. I have very frequent WiFi internet disconnection: after that, LAN internet of a second computer, located in other room and connected to the same router, is perfectly working. Restarting of router or simply swiching of/on WiFi Button restore a good (but not durable...) WiFI internet connection. WiFi signal at the site of iMac is good. Any suggestions?

iMac, Mac OS X (10.7.5), 3.6 Ghz Intel Core i5 8GB 1333 MHz

Thanks for suggestions, but recommended settings did'nt solve my problem.

Rather, I found the solution changing traffic priority parameters in router Quality of Service: this stopped WiFi disconnection (the reason is probably the presence a LAN connection to TV).

Below the procedure followed:

log into the D-Link DSL-2750B gateway (browser: http://192.168.1.1) --> Wireless Clients --> Advaced --> Advanced Wireless --> Qos --> WMM --> disabled --> apply
