who told you that? You may want to check your facts on ISM Wireless operating. Basicallt a signal can travel horizonal or vertical. Microwaves opeate at 2.4013 mhz so if your running channel six at 2.4667 I have never seen an ssid that says 7-11 microwave
Well, a cooking microwave would not be transmitting a SSID. It is a cooking device, using broadband microwave radiation, not a narrowband transmission. If you had access to a spectrum analyzer, when the oven was operated, you would see on the analyzer a broadband noise that covers all the 10 Ghz band (the oven operates at 2450 Mhz but it is coming out of a special vacuum tube called a magnetron, designed just to make microwaves).

They (the original designers and implementers of 802.11b) even knew that there would be interference and designed for most of that accordingly.

Hello from Adam Kb2Jpd
The frequency band that Wifi-B operates in is a junk band , a ISM band where medical, cooking, and consumer equipment can operate on top of each other as stated by the FCC. Since I can't see where you live, I can however tell you a few things....
If you live near a hospital or a convience store, they operate ISM devices that would wipe out the signal of your access point. Your local 7-11 microwave oven can be seen up to 3/4 mile away, even in Manhattan, where I live.
I don't know about your power output of your access point, however if you don't feel like upgrading to Wifi-B, the old Linksys B AP's put a lot more output power than say by D-Link's APs. My AP goes maybe 50 feet past my apartment awhile the Linksys can be seen down the block. Otherwise, check out the Linksys or look at the new Pre-N access points that promise further range using new tech at the transmitting and receiving end.
