    Hello all,

    As the title states I'm having several connectivity issues which don't seem to be fixed with any suggestions I've encountered in other threads.

    The nutshell version: With 3 different gateways I've had connection drops (both wired and wireless) which are increasing in severity as time goes on (starting as of about 3 months ago).

    The long version: I moved to an apartment a while back, bought my own gateway (Motorola/Arris SURFboard SBG6580), signed up for Time Warner Cable's 24 Mbps, bought Chromecast, installed PLEX media server (I'll explain the significance shortly), and ditched cable.

    For three weeks everything was gravy, then I started getting connection drops on all my devices (I use the ethernet cable for my laptop, wireless for Chromecast, Ipad, Iphone, etc.) It started with only a couple drops a day for about 30 seconds each, automatically fixed on its own. I noticed it happened, at first, on high demand sites or while surfing plus streaming from PLEX to Chromecast, but as the drops increased in frequency and severity (lasting longer and requiring me to power cycle the gateway to reconnect) it started happening without cause (the connection lights would go out on the gateway even when I wasn't actively using it). Eventually it escalated to the point where most of the day my connection would be cycling in and out continually and unfixable no matter what I tried (restarting gateway, computer, & Chromecast). What was really strange was that while some devices would be disconnected, others would work fine. Also sometimes I could be online despite the gateway and connection icon saying otherwise. For example, I'd have a playlist loaded on PLEX streaming to Chromecast and my wired connection would drop (no pages would load, no accessing email, etc.) but PLEX would continue streaming my playlist to Chromecast and playing all the media files. Other times Chromecast would give me connection errors, the Iphone also, but the Ipad and laptop would connect with no issues.

    After hours on the phone with TWC support troubleshooting to no avail they sent a tech out to check the lines. She checked the lines inside and out, ran diagnostics on her laptop, checked settings on mine, checked the gateway settings, and finally decided that this was not TWC's fault at all, the settings were all good (properly configured), so it must be a defective unit. I replaced it with a rental which the tech gave me while I would decide what to do next.

    Two weeks later the rental started doing the same thing exactly as I described above. Within a week it had escalated to be just as bad as with the last gateway. Since it was from the same manufacturer (Motorola/Arris) I figured I'll buy a highly reviewed one from another brand since maybe my computer just doesn't like the company or something.

    So I bought the Netgear C3700. The first 2 weeks were gravy again, but as of 3 days ago the same exact connection issues have started. It has not yet escalated to anything more than a couple of drops a day fixable automatically, but I don't want to wait until it gets terrible again to start troubleshooting.

    The reason why I mentioned PLEX and Chromecast is because I'm suspicious they (one or both) might be to blame based Google searches and the fact that prior to this I've never had similar problems and I haven't added or removed any software since moving in here.

    I've tried just about every advice I can find online and clearly I can no longer assume this is the third defective gateway in a row.

    From what I've seen asked in other threads: I use Norton 360 (and always have . . . since I bought this laptop about 5 years ago) plus Spybot SD which I only use for scans every now and then and not running all the time.

    Next time it happens I would log intothe Gateway with the wired device and look at the basic home screenand check the status of the cable connection, wireless, voice(if youuse it) etc... This would help on where to start troubleshooting.

    If the modem/router is not plugged directly into a wall outlet you may have a defective extension cord, power strip or surge protector. Or, the circuit may be loaded near capacity (probably not easy to determine in an apartment).

    Coolburn, I'll give it a try next time. Is there anything specific I should be looking for, or will it pop out at me immediately?

    TerryNet, I don't have it directly plugged into a wall. I'm using a desk with a built in surge protector. The desk has been through quite a few moves with potential bumps along the way. Would there be any other symptoms to look for in case that's the problem, or should I just go ahead and plug it into the wall and hope for the best? I hope the solution is really that easy.

    Thanks for the tips so far, I'll post back with any updates (if I have any) or unless someone else has any ideas.

    I don't know. Just trying to think of some cause for three different modem/routers to work fine for a short period and then start acting "weird" and getting worse over time.

    I would try that. If you get tech support for one of the modem/routers that will likely be among the first four or five things they have you do.
