maka 7 Posted January 9, 2011 Share Posted January 9, 2011 okay so i have my router hard wired is my pc, xbox relying on wifi are 3 laptops. 2 work all are running that monstrosity known as vista one of them wont work with the router. it will work when the network is all open (no security) however it wont work when it is on. (and will work wired) any idea what may be wrong. tried restarting modem, computers, laptop, laptops wifi adaptor but it always states limited or local connectivity Link to comment Share on other sites More sharing options...
CSC1 + 131 Posted January 9, 2011 Share Posted January 9, 2011 Could be an IP address conflict, do any of your devices have static IP's? You should also try changing the channel that the router is operating on, I believe 7 is recognised by all Windows OS's. Oh one last thing you really should put some security on it.

GaryW 160 Posted January 9, 2011 Share Posted January 9, 2011 (edited) Sorry - change of thought. It works when the wi-fi is open but not when it's secured? What level of encryption are you using and how old is the laptop/wi fi dongle on the affected laptop? Edited January 9, 2011 by GaryW Link to comment Share on other sites More sharing options...
caveat_civis 116 Posted January 9, 2011 Share Posted January 9, 2011 Are you using WPA encryption? With a laptop running Vista I would be surprised, but perhaps its wireless card doesn't support WPA. Link to comment Share on other sites More sharing options...
GaryW 160 Posted January 9, 2011 Share Posted January 9, 2011 It's not Vista, it'll be the drivers for the wirless card. I have a laptop running XP that can do WPA2-PSK with no problems. As the OP pointed out, it works on wired and it works when the security is removed so it does seem likely that the wireless card/drivers does support the level of encrpytion being used.

I didn't say it was Vista - I said I think it's unlikely on a laptop running Vista (i.e. one that isn't that old). But yes, it could be the driver rather than the capability of the adapter itself so I think that's probably worth a try first. Link to comment Share on other sites More sharing options...
maka 7 Posted January 9, 2011 Author Share Posted January 9, 2011 security is as followed. password set to access network WPA/WPA2 (personal PSK) TKIP + AES as the authentication tried all the other combos, but the laptop just always says "local" or "limited connectivity" Link to comment Share on other sites More sharing options...

I misread! security is as followed. password set to access network WPA/WPA2 (personal PSK) TKIP + AES as the authentication tried all the other combos, but the laptop just always says "local" or "limited connectivity" I'd have to say that it's either drivers or the wireless card being able to properly talk WPA/WPA2 and/or not understanding TKIP+AES.

Burnsy2023 2,895 Posted January 10, 2011 Share Posted January 10, 2011 You should also try changing the channel that the router is operating on, I believe 7 is recognised by all Windows OS's. All channels are seen by all Windows OSs bar channel 13. I would suggest using WPA with just AES encryption and seeing if that works. Link to comment Share on other sites More sharing options...
Wcarnby 196 Posted January 11, 2011 Share Posted January 11, 2011 escalate from lower security to higher security settings, to see which one stops being understood by that laptop. Alternatively, you can leave the wifi off, hide it from broadcast, then add mac encryption (aka no ips will be given to those whose mac is not recognized by the filter) Link to comment Share on other sites More sharing options...

That's not secure at all. 2 Link to comment Share on other sites More sharing options...
GaryW 160 Posted January 11, 2011 Share Posted January 11, 2011 Which takes the best part of a minute to get around. That's not secure at all. Absolutely right. there are plenty of programs that can sniff out a 'hidden' wireless router and MAC addresses can be spoofed very easily. Link to comment Share on other sites More sharing options...
Llama 30 Posted April 4, 2011 Share Posted April 4, 2011 Firstly make sure you're not using a Certificate Authority on your network. Secondly make sure that your computer has been assigned the correct DNS servers and gateway by your DHCP service on your router. Setting these manually might help: In the properties dialog of network connections for your wireless card, double check to make sure its set to get IP and DNS automatically from the router (IPv4) and that it's set to automatically detect settings in internet options. Else try setting the DNS as your router (192.168.1.254 for BT Homehub / 192.168.0.1 for Linksys and Cisco and 192.168.1.1 for Dlink) I'm a full time software developer and network engineer so if I you still need a hand just PM me and I'd be happy to run through different checks if the ones above don't work, RD Link to comment Share on other sites More sharing options...
