    Intermittent WiFi Problem

    I'm having a strange WiFi problem that I can't figure out. Despite part of my job being dealing with cellular and WiFi connections, I can't figure this one out.

    Occasionally all the WiFi devices connected to my router (D-Link) will lose connection around the same time, but not at the exact same time. The PS3 which is connected locally, will not lose connection.

    The laptops have to be "repaired" with the wireless wizard to work again.

    So for example, at 5:32 my computer might lose connection, and then at 5:35 my mom's computer might lose connection. I've tried to note the times these happen, but there isn't any type of pattern. I've checked the DHCP settings but I've got the lease set to 3 hours and it sometimes happens more frequently or less frequently than that.

    Everything that I can figure out in the router seems fine. I don't know where this problem started from, because I don't think anything changed on my side.

    I tried updating the firmware in the router, but that didn't help.

    It seems to have happened around the time that the cable upgraded my internet from 5 Mbps to 8 Mbps and I needed to reset my modem. But I'm not sure how it could be on their side when I don't think the PS3 loses connection, or any laptops that I plug in directly.

    Any ideas? I'm at a loss, and it's getting annoying having to repair my connection multiple times a day.

    Thanks.

    Have you tried configuring one of the devices to use a fixed IP address? I've had a few issues with DHCP on a Netgear router where things would drop connections at times that suggested it wasn't DHCP, but configuring things with a fixed IP solved it.

    It's a royal PITA having a fixed IP address on my laptop, when I visit somewhere else I have to remember to reconfigure it to use DHCP, then reconfigure it again when I get home again.

    I'll try that next. Currently I've tried changing the auto channel select to use Channel 10 only. Someone on another forum suggested this might be the problem, that all the routers in the area are using channel 1 instead of using correct channels.

    Any chance you are using VOIP. I was having a similar problem and reconnected with VOIP first in line before the router. Good luck

    Only use channels 1, 6 or 11. These are the only ones without overlap. Most routers use 6 out of the box, so effectively, you have only 1 or 11 to pick from for cleanest signal.

    At this one place, using the microwave oven was a sure fire way to cause a disconnect.
    Food for thought: if you aren't dead by 2050, you and your entire family will be within a few years from starvation. Now that is a cruel gift to leave for your offspring. ;)

    I'll try 11 then. 10 doesn't work any better then Auto was. Now I'm having even more ugly trouble. Annoying.

    Not using VOIP.

    Are you an avid or heavy internet user? Typically commercial wireless routers have a maximum amount of connections that can be made. Generally the number of connects are up in the thousands. Generally if a person has a good bit of Torrent usage or something like that maxes out the number of TCP/IP connections on the system and tend to get connectivity drops.

    Sometimes it is just a limitation of the "closed" firmware on the system and DD-WRT (3rd party firmware for routers) could help.

    You could also try picking up a low-grade business type router as well, but that could be cost prohibitive.

    Good luck!

    Nah, shouldn't have that many connections. I haven't torrented in a while. netstat shows I only have 26 active connections on my laptop. We have two laptops, two Droid X phones, and my PS3.

    I'd consider chucking the router. I have had a similar problem with a D-link router, and ended up returning it, buying a Netgear router. Another router I've heard good things about are Apple's Airport Extreme Base Station, or Time Capsules (take an AEBS, add a hard disk.)

    What is the model/type of D-link you have? I had a DIR-655 that intermittently dropped connection on WiFi, but never wired.

    It's a WBR-2310. Setting it on Channel 11 didn't seem to help. Gonna try 1 now.

    Try the following:

    1. as mentioned before, turn off DHCP and set all the devices to fixed-IP. You don't have that many, so fixed-IP is simple.

    2. turn off all proprietary stuff in the router, like the RangeBoost feature

    3. turn off any extra features you don't need, VPN-client, VPN-server, QoS, etc.

    4. set it to G only, not G/A/B mixed


    Unfortunately, DD-WRT doesn't work with that router. Gives you very fine control of routers for optimizing performance, such as transmit power or ACK timing.

    I bought a new Android phone last week and couldn't get it to connect to my Linksys router. All my other devices worked fine. Did some research and found a suggestion to update the router firmware. I did just that. My phone connected instantly and my other devices are still working fine.

    If I have any more trouble I'll try these things, but for now I think I might leave it. Seems to be working ok now. Not sure if it's because I'm just down to 2 devices (my laptop and my Droid X) now that my parent's left, or if it was changing it to Channel 1. Either way, seems ok now.

    Thanks for the help.
