let me rewind this topic.I am using a 3Com wireless router,i have upgraded also its firmware to its latest as found in their website.When i first use it in the middle east,me and some of my friends apply for a ADSL line there.When i used it using RJ 45 connection,i can fully enjoy its functions like wireless and extra 3 LAN ports.The problem we've encountered,all of my friends connection were cut,only me was able to surf the internet.Now, when i went home here in the Philippines i used it for my home network.I put one wireless desktop pc  for my daughter's room,me and my wife uses 2 laptops and one desktop for my gaming.My problem now is that i can surf the internet one pc at a time using Smartbro connection.I was really disappointed with my router.I dont want to throw it because i put some pigtail connection on it to extend its antenna all over my house,and it cost me so much.I lost my brain configuring it.
