I dont know if you are new to wireless or are just testing the water, however there is a lot going for wireless, as you may know the technology is line of sight from the transmiter(router) to the recever, it can be as far as 17 klm.
I think almost everybody is familiar with the state of eircom's cables in the rural areas ( as I post this thread my land line is down for the past three days, just another good point for wireless broadband) with the constant breakdowns and very poor service to make the repairs and their lame excuses that it is the bad weather!!!
lightening has no effect on wireless, nor high wind and rain. With the benifits of skype and voip, there is no need for eircom's wire or poles, and you can do away with the line rental and call charges( I save €66 per month)
I could continue to list the good points for wireless but I think that is enough for now, if there are some questions please post them.
