Hammie Posted November 12, 2006 Posted November 12, 2006 OK, this one is a little weird, so here goes: My home network is a Linksys WRT54G (v6, newest firmware) which feeds my desktop, a laptop, a Vonage adapter, and a Buffalo Media Station (all wired). The laptop is used for a voip program for radio amateurs called Echolink. The laptop is also the only device taking a static IP (.1.105) while the rest are dynamic from the router. This system works fine and dandy until I start up my other laptop (802.11g) and connect it to the wireless side of the router. When this happens, the static IP laptop loses its connection, and very rapidly regains it. It happens so fast that you would probably not see the hiccup, it if it wasn't causing all the open voip connections to timeout and disconnect. I have tried moving the voip laptop to the DMZ, which doesn't fix it. I should mention that the application on the laptop requires the router to forward UDP ports 5198-5199 to the host PC, which is why the laptop is set up for a static local IP. On another note (maybe different problem, maybe not), on the desktop PC (dynamic IP, wired connection), after I've downloaded a significant amount (high hundreds of MB, close to a GB) at one sitting, the PC will lose its connection to the Internet. All the other devices can still acces the net, which tells me it is a problem inside my router or the PC. If my ISP was cutting me off, it would disable ALL my PC's, not just the desktop. Also of note, the same problems have occurred on two different WRT54G's, one a v5 and the other a v6. Anyone heard of these Gremlins? Hammie Quote
stevevan Posted November 12, 2006 Posted November 12, 2006 (edited) Strange...never heard of that. I have all static IP's on my network (laptop, 3 Windoze desktops, and a Linux desktop) also running on a WRT54G, v6. I can run Echolink from either a Windoze machine or Linux and have no problem. If you find a solution, let us know. This sounds like one I'd like to file away in my "Things To Remember" folder. 73's, W4SJV Oh...and welcome to the forums!

TCH-Andy Posted November 12, 2006 Posted November 12, 2006 Welcome to the forum, Hammie I've heard of it happening with the Linksys - but I've not heard of a solution - sorry I'd suspect that a google may elicit some useful info. Quote
Madmanmcp Posted November 12, 2006 Posted November 12, 2006 I would guess that its a problem with DCHP, wanting to take control of the system. Make the laptop a static IP and see if the hiccup goes away. If it does then just get rid of DHCP all together and keep it a static IP system. When you startup the system all the wired computers connect and DHCP is not loaded because its not needed and everything works fine. As soon as you connect the wireless, DHCP kicks in and resets all the static IP's as it takes control so it can assign an IP to the wireless laptop. It needs to know whats available before it can assign IP's. This is probably whats breaking your connection. Another fix would be to introduce the wireless first so DHCP starts off first and is in control before the static IP's join. Quote
