Fucking obnoxious internet connection problem

edited July 2007 in Help / Advice Forum
So, I'm on a wireless network, and every so often (though, it's been getting more and more frequent) the connection will go down, then come back up. It's at the point right now where it's doing it every 30 seconds. By tomorrow morning, it'll probably be fine again for awhile, before going down every couple of minutes for awhile, then be fine for awhile. I highly suspect this is an issue with the ISP (Comcast) rather than my network, but I figured I'd ask here and see if there is anything I should be trying first.

Unfortunately, I have neither the coaxial nor the network cable required to run a wired connection, so trying that is out of the question.

    Does it still happen right next to the router? If not, it is probably a signal issue. Try boasting the output power. Depending on your firmware, the default handler ming be able to do this. You might need custom firmware.

    First I would determine whether its on your end or your ISP. Easiest way i can think of to check this is to ping your router the next time this happens. Assuming your on xp, to do this go to your start menu, run then type cmd (enter). type ipconfig (enter). write down your default gateways ip. Then type ping (default gateway ip) (enter). if you get three responses then its on the isp side. If it times out then it's the wireless connection. I had this same problem and it was my connection dropping but i found this solution and it stopped my connection from dropping out.

    A good way to check is to have a CMD window set to always on top and run:

    ping (default gateway) -t

    which just makes the ping test run and run. Then when the connection drops you'll be able to see either the 1000ms+ ping or the message "Request timed out"..

    It's worth noting that my connection is always either "very good" (full bars) or not there at all.

    Which band are you using, 11a, 11b, or 11g?
    11b operates in 2.4 ghz range, which can see intereference from microwaves, cordless phones, and of course other wifi networks. Putting your wifi in a band operating at 5 ghz might help (other devices also operate in this range).

    http://www.airmagnet.com/ may assist you in diagnosing your issues. Also for some reason, my PS3 hoses my internet connection for other clients on my network when it's signed onto PSN (it's connected via wire though, and hoses EVERYTHING not just wifi). I usually have to sign it off of PSN and reset my wireless router before other clients can connect again.

    No cordless phones here (no landline at all, actually), and provided the microwave doesn't interfere merely by existing, and that it actually has to be on, that's not the problem, either.

    I'm in Seattle, so, of course, there are six other wireless networks within range. That could be the problem.

    This basically sounds like your PS3 is hoarding all of the bandwidth for it's own greedy little self. Most routers you use at home (and the modems that love them) can get really flaky when you start pouring too much bandwidth through them for too long.

    I know my linksys wireless router freaks out if I have a couple of torrents running unchecked and it basically hoses my entire network till i unplug the router for a moment then plug it back in.

    You can try changing the wireless channel your router is broadcasting on.

    However, depending on the wireless card/software you use on your PC.. sometimes it's not so easy to change that client side if it doesn't pick it up right away.

    I can't remember what it's called, but there's an opensource wireless network detection software somewhere out there that will scan and give you info on nearby WLANs including channel and signal strength.

    If you can find that software, scan, find out what channel all the other chumps are using, then switch. Most WAPs are preconfigured for channel 6, the next most popular channel is generally 1. I current run on channel 11.

    Just double-checked: It's running on channel 11, wireless G and B. I switched it to just operate in 802.11g, see if that helps.

    Anytime you're having connection issues, make sure you powercycle your router and modem before you start digging deeper, since resetting the hardware fixes them 90% of the time.

    It might be worth noting that I had a similar issue with my wired network when my 4 year old modem started to die. Comcast will replace it for free if you bring them the original.

    I have had luck with rotating the access point 90 degrees before, which once greatly extended the range so whole house was covered and connection-life was improved.

    Yeah, my parents have had two cable modems die on them, both replaced, no questions asked. This one, however, is brand new.

    And yeah, I've power-cycled both the modem and the router many, many times. Sometimes, it seems to help, briefly, other times it doesn't do shit. I reset the modem to factory defaults last night, haven't had any problems since, but I fully expect it to start again. I also moved the modem a bit closer to my room, and around a metal table that was in-between it and me.

    How long has comcast been your ISP?

    I used to have adelphia, but comcast recently bought them out. Aparently they were doing alot of "upgrades" in my area, because myself and my friends started having problems within 2-3 months of comcast taking over. Then after about a month of issues, everything was fine. Now, since I don't work for comcast, I can only assume that "upgrades" took place, But none of my hardware or software settings changed, and one day it starts working again, and really really well at that.

    Two weeks exactly.

    And yeah, my parents had the same experience. It was a pain in the ass to get them set up, but it's been working fine since.

    If your firmware is uptodate after you reset the router to factory defaults, and it's a new modem, it could just be the service currently.

    Did you make your wireless connection require a WEP key? Or is it open to anyone within range? Sounds like you know enough to enable WEP, but just ruling out "LOLZ FREE WIRELESS" neighbors as a possible root cause.

    WPA, actually. Is WEP better?

    I'm in Seattle, man, pretty much the most tech-savvy city in the U.S. I'm not dumb enough to leave a wide-open network for anyone to use. :P

    WPA is better, don't ever use WEP. It's completely broken.

    When you say your connection is either very good or not there at all, this doesn't mean your connection to the wider world is dropping, only the wireless (but I am sure you knew that).

    Try changing it to B mode. B has greater reach and reliability. But it sounds like the wireless is just dying and rebooting, so if you can upgrade the firmware, do it. If you can't, send it back.

    :P figured as much, just had to make sure, Nah WPA is fine. As well, There was a period there for awhile where aparently my frequency was too high, outta the blue. I called em up, they came out, Knocked on the door, tested some stuff, swapped out some splitters and an old cable for a new one. And said "Voolah"

    I get this same bullshit on my PC, also with Comcast. They tried to blame my firewall, my PC, the router, etc, but none of those have changed, only my ISP (since Adelphia shut down).

    My router never has problems, it's the cable the just goes right out whenever it pleases (usually while trying to do something "new". If I haven't clicked a link in a while, or in WoW, if I haven't fought a mob in a while, as soon as I do, BAM, it goes out)

    Um... No. Based on the symptoms he is describing, it sounds more like an issue with his wireless router.

    He specifically stated that when this happens it is the wireless network that drops ( "It's worth noting that my connection is always either "very good" (full bars) or not there at all." ).

    Regardless of the state of the cable modem the wireless network should still be there. Intermittent connectivity to a wireless network is usually the result of interference from other wireless networks/devices. As suggested previously try changing the channel used by the modem (1, 6, 11 are the common ones, if those don't work try 4 or 8).

    Do you have a 2.4ghz cordless phone? If so does your connection loss coincide with the usage of said phone? Any wireless security cameras, baby monitors, etc. in your general vicinity?

    I'd say we should be blaming Comcast. I know when this shit happens to me, my wireless network is fine (I can always stream shit from my PC to the 360, for instance), but my modem will just randomly disconnect the entire fucking network from the internet.

    When you say "lose your connection", do you mean that Windows or your wireless management software tells you that your Wireless is Unable to Connect or do pages just stop loading and/or MSN/AIM disconnects?

    I agree. It's most likely an issue with crowded frequency channels (from other WAPs), low signal strength, or the router's just plain dying.
