Hey Wash,
Thanks for your email. My pal had told me that he sometimes creates a hotspot using his phone and surfs the net using his data bundle. The points you have raised are quite reasonable, I must say, but as a network admin, I would use different subnets for LAN and WLAN e.g. Class C addresses on the WLAN and Class B addresses on the LAN or vice versa. Anyway, I think that's a minor detail. He needs to use his bundles by creating an AP using his phone.
BTW, it seems like it's only HP/Compaq laptops which have this issue. Why would the other makes allow both ethernet and WLAN?

And I think that the following statement, derived from the same URL, makes so much sense:
"*It's perfectly normal, you cannot have two concurrent connections.*"
Imagine the following:
Both WLAN and Ethernet are active. Your LAN subnet is 192.168.x.x/24 Your WLAN has obtained 192.168.x.10/24 while your Ethernet has 192.168.x.11/24. In both cases, Gateway is 192.168.x.254. What is the use??
Imagine another scenario, where the AP is wired to a different Internet provider while the Ethernet is wired also to a different Internet provider.
You get assigned two different network addresses on the WLAN and Ethernet. However, all traffic gets sent out via the Gateway with the highest METRIC (the lower number). It means some services fail unless you specify some static routes, right? Something along the lines:
route add -p 0.0.0.0 mask 0.0.0.0 interfaceNUM (for WLAN) route add -p 192.168.x.0 mask 255.255.255.0 interfaceNUM (for Ethernet)
Actually, someone please tell answer me this question: In scenario 2, suppose I want ALL Internet traffic to go out via WLAN and all LAN traffic to go through the Ethernet, are those commands really correct??
Back to @Simon Mbuthia and his pal - what was the initial intention of having both interfaces active at the same time?
I must comment on this and say that is a windows failure esp of W7. On XP this worked/works quite fine and acts like redundant or if you want to test some gargets on one card/network interface and still be on internet on the other. Am on Ubuntu and i connect both wireless and cable at the same time for i test alot of stuff whilest i want still to access network pheripheries or internet! OR. Like mine here, if by mistake the cable is unplugged or power goes off on my switch my wireless picks up without any second thought! So is vice versa! wilson@wilson:~$ ip a 1: lo: <LOOPBACK,UP,LOWER_UP> mtu 16436 qdisc noqueue state UNKNOWN link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00 inet 127.0.0.1/8 scope host lo inet6 ::1/128 scope host valid_lft forever preferred_lft forever 2: *eth0*: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq state UP qlen 1000 link/ether 88:ae:1d:7b:e2:fc brd ff:ff:ff:ff:ff:ff * inet 192.168.100.121/24 brd 192.168.100.255 scope global eth0* inet6 fe80::8aae:1dff:fe7b:e2fc/64 scope link valid_lft forever preferred_lft forever 3: *wlan0*: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq state UP qlen 1000 link/ether 5c:ac:4c:78:21:e5 brd ff:ff:ff:ff:ff:ff * inet 192.168.100.122/24 brd 192.168.100.255 scope global wlan0* inet6 fe80::5eac:4cff:fe78:21e5/64 scope link valid_lft forever preferred_lft forever wilson@wilson:~$ ip ro *default via 192.168.100.254 dev eth0 proto static * 192.168.100.0/24 dev eth0 proto kernel scope link src 192.168.100.121 metric 1 192.168.100.0/24 dev wlan0 proto kernel scope link src 192.168.100.122 metric 2 Niatia !

I have just come across this link http://answers.microsoft.com/en-us/windows/forum/windows_7-networking/window...
I have sent it to him and I hope it works. Says that HP/Compaq laptops have a certain setting that needs to be changed. Might you guys have tried this by any chance?

Happy new year friends,
I have a friend who just bought a HP laptop which came bundled with Windows 7. He informs me that he is unable to use both Wireless and Ethernet at the same time and in order to use either, he has to disable the other. I am not
My work laptop (HP EliteBook 8440p, Vista Enterprise) has the same behaviour, but I was under the impression it's a custom config for security reasons. I'll check with out HP IT guys and see if they can help.
