Until recently I was using the same laptop at the same address I've been at the last few years, and I never had any problems with the wifi connection to the router. The wireless interface is the ipw2200. Then I got another secondhand laptop with the iwl4965 interface. I've noticed in KNetworkManagement the signal strength never appears as high as on the other laptop, but most of the time I have no problems. Every now and then, however, maybe every couple of days or so, connectivity goes haywire. Sometimes if I switch the hardware wireless switch off and back on again, I'm back to normal. Sometimes I try that, I restart, I go mad tearing my hair out and have rebooted the router and the problem can persist for a couple of hours or so. At first I was running both machines side-by-side and I thought one might be 'stealing' the signal from the other because things seemed worse when they were both on, and less comprehensively I've now had the odd similar problem on the old machine when the new one isn't running. I tried changing the wireless in YaST to traditional setup using Qinternet. There I can do a soft hang-up and restart, which also sometimes works, but not always. Trying to browse to the router homepage at 192.168.1.1 often doesn't succeed at these times. I know nothing about pinging generally so maybe I'm doing something stupid here, but the peculiar thing is that when trying to ping 192.168.1.1 I consistently get results like these: PING 192.168.1.1 (192.168.1.1) 56(84) bytes of data. 64 bytes from 192.168.1.1: icmp_seq=12 ttl=64 time=2.97 ms 64 bytes from 192.168.1.1: icmp_seq=18 ttl=64 time=2.87 ms 64 bytes from 192.168.1.1: icmp_seq=30 ttl=64 time=4.57 ms 64 bytes from 192.168.1.1: icmp_seq=36 ttl=64 time=2.90 ms 64 bytes from 192.168.1.1: icmp_seq=39 ttl=64 time=6.68 ms ^C --- 192.168.1.1 ping statistics --- 39 packets transmitted, 5 received, 87% packet loss, time 38004ms rtt min/avg/max/mdev = 2.872/4.003/6.687/1.489 ms whilst if I ping one of my websites housed on a server in another country (UK) in quick succession I get this: PING username.me.uk (212.159.8.91) 56(84) bytes of data. 64 bytes from homepages.plus.net (212.159.8.91): icmp_seq=1 ttl=239 time=75.0 ms 64 bytes from homepages.plus.net (212.159.8.91): icmp_seq=2 ttl=239 time=68.2 ms 64 bytes from homepages.plus.net (212.159.8.91): icmp_seq=3 ttl=239 time=70.7 ms 64 bytes from homepages.plus.net (212.159.8.91): icmp_seq=4 ttl=239 time=74.5 ms ^C --- username.me.uk ping statistics --- 4 packets transmitted, 4 received, 0% packet loss, time 7184ms rtt min/avg/max/mdev = 68.280/72.144/75.034/2.791 ms (At the time of typing this both are behaving now with 0% packet loss). I would have expected these results to be the other way around. What's going on? Is it just a flaky wireless card that sometimes drops out, poor drivers, the network card going to sleep or some power management mode, interference from another neighbour's network, or something else that could be responsible?
