i am using ubuntu 64bit

Code:

i use internet via wifi and access a switch using ethernet port

Code:

My wifi works . When I connect ethernet cable then internet (wifi is the access source) does not .
Switch access is on 10.3.255.something and wifi is on 192.168.1.something .
Both networks don't conflict .
How can I get both to work simultaneously ?

Thanks.

PS:link-local does not allow setting ip on an interface .

routing ?

$ route -n
# netstat -r

Basically 3 parts, the interface needs an ip, the firewall needs to allow the use of the interface, and the routing needs to tell it how to use the interface. If it's not one of those three then hardware might be the issue. These 3 parts need to be in play on both ends of any network connection. DHCP normally does most of this setup for you, but it can be done manually.

After asking about routing for years, can none of what you've been told before apply?

Hello #Sumeet. I've seen a shorter routing command as required posting on LQ: ip r
I didn't understand link-local, so I checked wiki and saw it is the mysterious 169.254.. which I get when ISP connection not working.
Yes, more perfect posting would avoid the hidden reply above. I didn't want to click on the "Remove user" link on the above post, sorry; above poster has been repeatedly warned to learn basic human NVC and follow LQrules to no avail.

Before going off on how bad the reply is, you may want to check out the OP's posting history. You may also want to spell the OP's name correctly, if you're so concerned about their feelings, and since you say you don't want to even READ a reply, how can you comment on its content?

If you have a problem with the post, then REPORT IT...if you can, you may also want to point out how it violates the LQ Rules. Your post certainly violates LQ Rules, by violating:

When posting in an existing thread, ensure that what you're posting is on-topic and relevant to the thread.

Please, show us where you've helped the OP with your reply, which didn't address any of their issues. The OP has been asking such questions for FIVE YEARS now; asking them why they can't apply knowledge they've been given multiple times before certainly seems valid.

The 169.254.. route is generally setup by avahi. And happens when no other route is available, it's a dummy route, something about audio or some such. I tend to stop avahi and delete that route when I see it. Although generally I avoid installing things (or distros) that install avahi to avoid such issues / quirks / features / innovations / ...

@sumeet inani this thread has been closed. Please contact administrators if you wish to provide additional follow-up on this thread topic and it can be reopened. Please also note that starting threads and failing to follow up on discussion points or respond to questions for additional information makes it more difficult for other LQ members to provide you with any assistance. Since you have started other threads, responded to those threads, and marked them solved since this one has been opened, my assumption is that you are not going to provide any update which can help any of Shadow 7, TB0ne, or iPad be of any assistance with your problem. In the future if you find a solution, it is helpful to others who see the same problem to know that you have found a solution and what solved the problem.
