Wireless Question

[ChaosdaJoker]

Hey everyone

Currently i dont use a Wireless Router im still cabled, but i wanna switch out to one so i can use the laptop anywhere, but still have the cable for the main comp, my question is however, the house i live in is solid brick, is this going to cause a problem with wireless signal at all, when i asked in the store, the guy asked do you use wireless phones, i said yes, he said it will be fine, but i dunno,

Any help would be great, also is there 1 router better than another for wireless or are they all the same????

Thanks
