View 6 RepliesThe automatic connection to the preferred network (with a strong signal) does not occur immediately. When I choose it in the list of preferred networks and click on 'connect' (with the password present of course), a message appears stating that the computer is connecting to the network. However, after some time nothing happens and the message terminates. There is no other information given (e.g. 'the computer failed to connect..."). After up to 15 mins or so, the network connects automatically (not sure if this has anything to do with turning the router off and on, restarting the computer, turning the wireless adaptor off and on....)

View 1 Replies View RelatedI'm using an E2500 router and EA2500 adapter. I started from scratch today, uninstalling then reinstalling the software. As instructed in the video on the Linksys website, I plugged in the router, then the computer to cable to the router, then the router to the modem. When all was finished, I disconnected the cable from the computer to the router. Should I have left that in? When it's in, multiple networks shows in Network and Sharing Center.

View 1 Replies View RelatedI have Dell Latitude D620 and bought it refurbished, I did NOT recieve a backup drivers and utilities disk with the laptop.

After reinstalling Windows XP it will not connect to the Internet at all. Even with the ethernet cord directly to the modem.

I am not that computer savvy and do not know what type of wireless card I even have.

WIFI is not working in my laptop after installing OS (windows 7). i had LAN drivers installed (now internet is working only through network cable not through wifi)
I am passing my computer on to a family member and wanted to give them a fresh install, so I used the Windows Vista (32-bit SP1) disc that came with the laptop and reinstalled Vista on the computer. Everything worked fine until I wanted to connect to the internet, then Windows said that there were no networks available. When I selected "Why can't windows find any networks" it said that "This computer does not have a wireless network adapter installed and configured". I put in the Dell Driver's and Utilities CD that came with the computer and installed the drivers that seemed related to networks or communications, but the problem persists. I'm assuming it is some sort of driver issue (as the computer was using wireless internet before the reformat (just hours ago) and so the device itself seems to be working.

View 2 Replies View RelatedI have a DMVPN network with 2 hubs (2821's). This setup is used for VoIP applications over the Internet for teleworkers. At the main hub site I used to have only 1 Internet feed which was DSL with a static IP. Now I have 2 WAN feeds for this site - 1 FTTB w/ PPPoE & the DSL with static IP. Since this site also hosts a PRI, I want all voice communications to go through the FTTB link instead of the DSL for obvious reasons, but keep the DSL as DMVPN Hub for all NHRP lookups as this link has a static IP address & is very stable. We originally put the PRI router as a DMVPN spoke which connected through the FTTB link, with another router acting as the DMVPN hub on the DSL link. This was obviously a waste of machinery. I want to combine both routers into one. So I tried something like this (don't laugh):
Gi0/0 to FTTB (Dialer1 connects to Internet)
Gi0/1 to DSL (Public IP towards 877 demarc)
Tun0 attaches to Dialer1 public IP and connects to other spokes, no VRF
Tun1 attaches to Gi0/1 public IP and acts as DMVPN hub (ip nhrp map multicast dynamic) under VRF "Hub"
EIGRP AS 1 is set up twice, once under router eigrp 1, and the other using router eigrp 2 using an address-family under the Hub VRF.This kinda works but obviously Tun0 & Tun1 do not speak to each other. I also had to remove the ip nhrp map instruction that pointed to Hub1 on Tun0, as this was causing a weird condition in the router where it was repeatedly trying to connect a tunnel to itself, and crash the router because the NHRP process would go haywire. So my users must rely on the Hub2 to get a NHRP lookup for the PRI site. If Hub2 goes down, everything works in the network except for tunnel connections to the FTTB link. I'd rather not have to configure 2 tunnels on each spoke router unless I really have to.
URL What changes are needed to the 2821 config that is behind another Cisco router? And what static ports should be opened on the MAIN Cisco router that is in front of the 2821?
