WhollyMindless Posted January 12, 2009 Share Posted January 12, 2009 Check your router's uptime. I had one router that would reset on it's own pretty regularly. A firmware update solved it. P.S. Where/How did you do that scan? Quote Link to comment Share on other sites More sharing options...
vector Posted January 12, 2009 Share Posted January 12, 2009 a little more detail on what exactly is happening would be helpful. are you not able to see the routers signal from your laptop? do you still have internet access if you use the ethernet connections? what type of router is it? how far are you from the router? what type of wireless adapters are you using and how are they configured? what channels etc etc. Quote Link to comment Share on other sites More sharing options...
Sparda Posted January 12, 2009 Share Posted January 12, 2009 Try choosing a channel that is as far away from the other AP's around you. Other thing that effect such things: Cordless phones Wireless video senders Wireless speakers Quote Link to comment Share on other sites More sharing options...
digip Posted January 12, 2009 Share Posted January 12, 2009 Even a microwave oven can kill a wifi connection. It could be interference with some other device, but if you suspect a DoS of some sort(more likely someone sending deauth packets and not doing an actual Denial of Service attack - espeically over wifi) fireup a live disc of linux and run Kismet and wireshark. See what other routers and users are in your area and where they are sending packets. Is anyone connecting to your AP? Is there even any wireless devices around other than yours? etc...

Mad Pierre Posted January 12, 2009 Author Share Posted January 12, 2009 On one getting on the router. If it's dropping due to other device's. then fair do's Quote Link to comment Share on other sites More sharing options...
VaKo Posted January 12, 2009 Share Posted January 12, 2009 Change the channel, I had this issue and it turned out that someone down the street was interfering with my wireless. Quote Link to comment Share on other sites More sharing options...
ansichild Posted January 12, 2009 Share Posted January 12, 2009 I have this issue with my old Linksys wifi router. Has anyone used a router that's completely rock-solid that they could recommend? It might be worth the extra bucks for a more reliable connection. Quote Link to comment Share on other sites More sharing options...
rtc443 Posted January 13, 2009 Share Posted January 13, 2009 not sure if this would help but like every1 said above...change channel...check for anything that emits transmits whatever and make sure that it is not interfering with ur wifi.....my linksys router would completely die when my phone was turned on. the signal would be great but the speed would drop like a rock.... turns out that linksys routers and the cable vision "Atlantic" i believe modems fight eachother if there close together...as in sitting on top of it. I changed the channel and now have no problems...idk if that helps but good luck Quote Link to comment Share on other sites More sharing options...

Deathdefyer2002 Posted January 14, 2009 Share Posted January 14, 2009 Yes, One of the BEST Wifi Systems that I have used is Rukus Wireless. It seems to work Flawlessly and is a breeze to set up.. It kinda is like Wireless for Dummies. Its kind of expensive though. Quote Link to comment Share on other sites More sharing options...
vector Posted January 15, 2009 Share Posted January 15, 2009 how is your signal level when you get dropped? Quote Link to comment Share on other sites More sharing options...
Sparda Posted January 15, 2009 Share Posted January 15, 2009 how is your signal level when you get dropped? It's probably full. Quote Link to comment Share on other sites More sharing options...
h3%5kr3w Posted January 15, 2009 Share Posted January 15, 2009 jesus, what type of router spec do you have? if that's 802.11N man I gotta get one of those.. that coverage is wild! at first I thought maybe it wasnt a router and your talking about a cellbased-wifi connection.

Mad Pierre Posted January 15, 2009 Author Share Posted January 15, 2009 My router a D-likn G604T. I've had it around 2-3 years now. The wifi allways been fine, just that the last two month's it's been dropping. As for singal strength that's allway good-to very good, as I'm only a wall/ceiling away, of apporx 15ft.

Mad Pierre Posted January 15, 2009 Author Share Posted January 15, 2009 No I've bought any new gear in the last two months. no wireless no new hardware. Quote Link to comment Share on other sites More sharing options...
Mad Pierre Posted January 20, 2009 Author Share Posted January 20, 2009 Update it only drop signal when two clients are connected via wireless.Two clients that are allowed on the network i.e my own gear. Due you think this maybe a sign of the wireless router breaking down.it's about 3-5 years old. Quote Link to comment Share on other sites More sharing options...

SomethingToChatWith Posted January 21, 2009 Share Posted January 21, 2009 Restart/reset it. Make sure it has the latest firmware. At 5 years old its probably seen better days... Quote Link to comment Share on other sites More sharing options...
h3%5kr3w Posted January 21, 2009 Share Posted January 21, 2009 I may try this myself as I have been having some strange things like this happening myself (but the signal doesnt drop, the bandwidth just stops abruptly, and I had some issues with my wireless printer tonight as well. The settings were right, it just wasnt connecting...) I am using dd-wrt though, so it could be that, but it's been only recently that mine is acting funky... WRT54G - ver. 6 oh and just so everyone knows, yah, I did disable telnet :D Quote Link to comment Share on other sites More sharing options...
Mad Pierre Posted January 21, 2009 Author Share Posted January 21, 2009 Just took a look at my router. the nut hold the sma connector to the router body was loose.
