Linksys tech support said if I upgrade my 802B wireless router to a "G" that I will get internet speed improvement even though my 3 wireless network cards remain "B". Is this true ? They said the theoretical 11 mps of the "B" router is being divided by 3 (due to the 3 computers on the net with "B" network cards- even if two of the machines are idle and unused). True ? They also said that even though with the presence of slower "B" network cards such that they couldn't enjoy the 54 mps of "G", at least they would be allowed to max out at 22 mps rather than having their 11 mps throughput or bandwidth being divided by 3. True ? Any other reason why my internet connection is so slow ? Thanks for any help.
