How to change a MAC address?

Hello all, this question is for my husband. He is currently living in Korea....anyways this morning his internet shut down. His router is showing that he still has internet access, but his computer is not receiving it. He reset his computer and when I called him, he told me that he believes his mac address has been blocked. Is there any way around this? I can call him on his cell but that is very costly. We always kept in contact through the internet via msn. How can he fix this? Is there a way to fix this? He isnt sharing his internet or piggybacking on anyone elses. Someone please help!!!!How to change a MAC address?
Some older Wifi cards let you change the MAC address in the device properties. You can get another wifi card for like $20 or you might be able to find some software that will let you change your MAC address.How to change a MAC address?
Unlikely that MAC address is blocked as the MAC address presented to the ISP is that of the router, which is connecting. Depending on which router he's using, it probably only has a NAT based firewall which by default, allows all outgoing connections so unless he's configured his router to block himself, it's not going to be that either.



Sounds like a problem at the ISP end, could be a DNS server is not responding for some reason, which would give exactly those symptoms. Problem is, there are so many possibilities, from the computer client right through to the ISP.



It could also be a faulty router, corrupt IP stack, faulty network adaptor, cabling etc etc. But assuming he can open his router config page, therefor meaning his computer is definitely connected to the router, and he is also sure that his router is definitely connected to the ISP, then he needs to contact his ISP
i think MAC address cant be changed ...they are hard coded..!!!



but due to manufacturing defect ....two Network Interface Card(NIC) can have the same MAC address...!!!!!!!



so...i think ...tell him to buy a new NIC...that will be better...!!!!
You can probably spoof the MAC address in some way, but that on'y masks the symptoms, it doesn't solve the problem. First of all, you talk about something being blocked on his end...so if this is the case, then the issues needs to be fixed on his end. Has he contacted whoever provides the Internet service?



Unless there's some security issue in play here, or his system is infected with some kind of malware, the first place he needs to look is at his local connection.
simple tell him to reconfig router so the firewall does not block MAC addresses.

However i doubt this is the problem since MAC addresses don't change. They r unique to the device.
