i had to purchase a third party router due to the shocking service using the hub provided...am i able to connect my vm wifi boosters into this also and will there be any impact on speed/reliability

hi, is it me or is virginmedia wifi terribly unreliable? it constantly drops out and the wifi throughout the house is probably 1/10th of the speed that you ate advertised at getting?the hub has already got the extra power booster cable going into it ...
