Hello

 

I have a Motorola SBG6580 router that was supplied by my Internet provider Brighthouse(time Warner) and I am beginning to suspect it may be the cause of my problems.  For the past few months, I've been having issues downloading programs and such.  Many times, most of the time, when I go to install a program or app, it ends with an CRC Error in the file.  It began to show itself with issues updating Norton Anti-virus but shows up when trying to download and install other items.  I just figured it to be an issues with pretty much every item that is linked to the internet through this router.  My PC, my Other PC(Both plugged into the router).  Every computer that is linked via the WiFi also seems to have issues including my son's WiiU.  It continues to fail in updating.

 

Is there a way foe me to run a diagnostic on this router to test and see if it truly may be the cause of the download issues?

 

Thanks You.

I would contact Bright house and have them test the lines into the house. From my research bad connections or improperly split coax lines (the main feed should NOT be split prior to the modem) were the issue. One solution given was to bridge the modem and use a separate router, this is only a bandaid however and doesn't resolve the issue only bypasses it.

OK.  I'll give them another chance to look it over or replce it.  They had someone check the lines remotely and said everything was OK.  The service tech that came out really didn't fill me with confidence.  I'd been thinking it was actually my computer causing the issues until I plugged in a very old desktop that I hardly ever use and began getting the same issues.  That made me start looking at other devices and seeing it in them also.

Another way to test is put a modem without built in router in place and connect directly to the modem. Then access the modem stats page that way and get all your modem stats for a baseline.

Update.

 

So after a few months of the Tech people looking at things and telling me everything was right, I actually called, instead of Chatted and online serviced, their tech people and was told that my hardware was wrong.  Brighthouse had increased my service to 150mb speeds and not changed my router.  I needed a new router to get the speeds I was supposed to be getting.  They came in today and replaced the router with a newer dual band unit and all my troubles have gone away.  It took me this long to get it replaced since I am never off and home during their regular business hours.  While the wife was off for Christmas break, I had her call to have someone come out to look at it and was told by the Tech person there about the issue.

 

I took less than 10 minutes of actually talking to someone on the phone instead of supposedly online chatting with tech support who was telling me they were remote checking their equipment and all was fine.

 

I wish I'd figured it out before I wiped out my system, thinking there may have been a virus or some type of hardware issues......

Thank you for letting us know. Sorry to hear it was such a painful experience to get it resolved.

Any idea why the router  and network speed differences could have been the cause?  I would kinda understand that the speed differences would have caused problems way back in the days when I was trying to communicate with 600baud network with my 2400baud modem or vice versus.

 

I would think the today's technology wold have allowed the slower speed router to correct and accept the packets that were being delivered, or at least sending the signal from the provider to slow it down while they were sending it.  Aren't those kind of handshakes supposed to be fully automated?

 

Just more curious now since I'm not very fluent with the technical side of things these days.  My major tech knowledge only really goes back to the days of the 286.....  I didn't keep up too well after that.

 

Thanks

Without knowing a lot of hardware specifics. My guess is that the hardware and firmware of the older setup had a bandwidth capacity threshold.

It was just one of the Run of the Mill Motorola DOCSIS 3* routers.  I had the model number written down somewhere but can't find it now.  I was going to look it up online to see if there were any known issues with it.
