similar to: Why can't the CentOS get dynamic IP address in WIFI environment?

Hi everyone, I'me having trouble with a CentOS 7 guest running on a Hyper-V host. For some reason, the CentOS guest randomly drops its IP address. Running "systemctl restart NetworkManager" on the console will restore IP connectivity without a reboot. I think that DHCP is timing out, but I'm not sure what to do about it. Is there a way to tell NetworkManager to keep trying after

Dear All, I'm trying to configure wireless card on a Dell Vostro 1540. I had a look at this site : http://wiki.centos.org/HowTos/Laptops/Wireless/Broadcom?action=show wireless card :# /sbin/lspci | grep Broadcom 12:00.0 Network controller: Broadcom Corporation BCM4313 802.11b/g/n Wireless LAN Controller (rev 01) I decided to follow the ELrepo instructions suggested on the site :

I am having trouble with recovery. Today due to electrical work I powered down my networks Router / DHCP server. My Centos 7 host machines lost their DHCP lease (they are actually static leases). Once I power my Router / DHCP server back up none of my virtual machine were accessible. It appears that when the DHCP lease was lost on the virt server the bridge of the KVM guest were all losts. A

Hello, I have the AR9285 wireless adaptor on an HP DV6-2128ca notebook. I can see it. it comes up in NetworkManager but never gets an IP. the router is a linksys using WPA/PSK security. Would/could someone please help me out trying to get this to work? Output of several commands follows: dmesg: ath: EEPROM regdomain: 0x69 ath: EEPROM indicates we should expect a direct regpair map ath:

This problem still bites us. I've tried to play around with DHCP settings (rd.net.timeout.dhcp, rd.net.dhcp.retry) to no avail. I'm happy about /any/ hint.

Hi, kickstarting fails due to problems with host resolution, even though the network seems to be properly configured through DHCP. eno1 and eno2 are both attached to the network, but only eno1 gets an IP via DHCP. Still `curl` cannot resolve the mirror host and the kickstart host during dracut-initqueue: rdsosreport.txt ------------------------------------------------ [...] [ 14.780428]

I'm migrating my son's Dell laptop from Vista to CentOS 5.3. He came back from each of his first two years of college loaded with virii and trojans. This year he said "Dad, can you give me Linux?" 5.3 went onto the laptop easily and after doing some research, I applied the guidance for getting multimedia working and got the nvidia driver loaded. That works great. Last
