As I said above my computers internet has been going out at specific times every day. I am on windows 7 with fios. My comouter is the only one affected by this and it blocks both wired and wireless. There are no sceduled tasks on my computer and no virus scan going. My computer states it has internet acces in the bottom right hand corner in the task tray. I really don't know what else to do anymore it has been going on for weeks and I have no idea anymore.

All throughout the world, ISPs promote their services for bandwidths and low costs. But they never assure that they can provide consistent internet connection to their users.

In your issue, I suspect that your ISP is not offering a consistent connection. It is better to get an assurance from your ISP that you are getting the right bandwidth in the consistent way all through out the way. Also check whether there is a packet drop in your connection through ping test.

Then you can think of other issues.

I recently had a similar situation, and the issue turned out to be resolved by upgrading from a DOCSIS2.0 to DOCSIS3.0 compliant cable modem. A similar situation also occurred when I upgraded from DOCSIS1.x to DOCSIS2.x some years ago.

Not saying that's what the issue is, but it's something to check especially if you can confirm your ISP changed/updated DOCSIS version or sub-version support between the time your service was working "OK" and the time it started "Failing". An ISP also may not support ALL the standards associated with a given DOCSIS version, including "downward compatibility" and the same is true regarding individual modems, which further complicates the issue.

In my case, the ISP was providing consistent service as far as THEIR tests on THEIR end showed...but at my end it turned out to be the cable modem (Linksys/Cisco CM100) that proved to be the "internet" bottleneck (aka performance and availability inhibitor). It caused both repeated and and/or intermittent internet performance "hiccups". I first noticed symptoms when YouTube buffering started "stalling" and video would stop playing for awhile...then resume after minutes passed...but my thought processes didn't immediately make the connection. I just put it down to recent changes in YouTube download functionality (I think driven by an anti-copy/download scheme, they stopped using temporary files on the system drive and started using only limited real-time RAM buffering (which causes other problems...bu that's another issue entirely)).

The ISP support team's standard "diagnostic" flow-charts did NOT make the diagnosis and did not help resolve the issue. It was left to me to figure out...both years ago and just recently...very disappointing since I would think this would be a common problem whenever the ISP changes their standards compliance at any level.

BTW, while in both cases the ISP still claimed to "support" the prior DOCSIS version and the old modem, performance at my end was still severely affected in each case.

In the most recent instance, when I changed to the newer DOCSIS supporting modem, ISP "download" performance increased from about 13Mbps* to consistently above 30Mbps (near the ISP service tier maximum for "download") and "upload" increased from about 5Mbps to consistently about 20Mbps (also near the ISP service tier maximum for "upload") using It did also depend somewhat on which ISP target location I used to run the test (e.g. a San Diego server v. a San Francisco or Austin server). In addition, server distance, capabilities, and real-time loading (other users) can affect reported performance at any given time.

The new modem, a Surfboard SB6121 also provided "channel bonding", which when also supported by the ISP could theoretically also improve performance and consistency. For more info on that, see internet search terms [channel bonding in cable modems]

Also, keep in mind that simply changing from a router that supports "10/100mbps" to "10/100/1000mbps" (aka gigabit) will not likely address things if DOCSIS is the issue unless the performance tier guaranteed by what you're paying for your ISP is very high (eg greater than 100Mbps)...although you might see a computer-to-computer performance improvement on your side of the router assuming your computers also each supported "gigabit" in both hardware and software. Wireless performance would be separately limited by your wireless connectivity even if all devices on "your" side claimed to support "gigabit" (e.g. just claiming gigabit network capability doesn't magically make it so in practice).

* Complicating the issue...
Terminology Note: when discussing network bandwidths there is generally speaking, no difference between sites that use the label Mbps and those that use the label mbps when evaluating network performance. In these cases "B" is the same as "b" and are both referring to mega-"bits" per second. However re: "M" v. "m", I think the sites using "M" instead of "m" are simply trying to strictly differentiate between the standard conventions of "M"=mega (10E+6, million) and "m"=milli (10E-3, 1000ths), although "m" is often used interchangeably when discussing network metrics.

There is however, a huge difference between MBps (Bytes per second) and Mbps/mbps (bits per second). Even so, YOU have to be sure what is being referenced to be certain you are comparing apples to apples. Some test sites and/or reference materials do not properly distinguish between the two and just confuse the issue.

To make clear that I had a similar problem recently and figured that nathan (and others) could be going through the same/simiar issue because of the timing. My ISP (without warning) changed DOCSIS compliance specifics. Even though the ISP "still supports" DOCSIS2.x and the specific modem (CM100) I was using, I also had intermittent loss of and internet performance issues until I replaced it with a DOCSIS3.0 compliant modem.

I'm kind of thinking it is a different isue than that and not an isue with my router but one on my machine because it only affects my computer and not others on the network and my service hasnt changed at all before or during the time i have been having the issue besides the blackout. Also I realy thought it was weird but the time didn't change with daylights saving time but two weeks later so now the time moved back from 130 to 300 to the original blackout time of 230 to 400.

Then the only way I suggest is to check out the PC connectivity through another wired or wireless line. What I mean to say is to connect the PC to some other Wi-Fi or wired source from your neighborhood, friends house or do something to change or replace the ISP source.

If you are able to connect to that service, then your PC seems to be safe and free from all kinds of hardware troubles and the problem is in between the chair and the keyboard.

But still I suspect that there is either a packet drop taking place during the said time or some kind of interference happening during that time. Like if your accessing your TV simultaneously, then keep it atleast 5 meters away from your PC.

If not the problem seems to be at the server end. May be you should install a software which keeps a tab of your login and logout and the time you accessed the internet so that you can have a valid proof to prove your point.

BTW Is your PC a desktop or laptop? What is the source from which you access the internet during the said time- Is it a wi-fi router or directly from the router through a cable or a data card? What antivirus do you use?

It is a desktop hooked up to both wired and wireless internet but I have tried it with either disabled. I use to have mcafee but it was really intrusive so I got rid of it and went no virus protection for a bit but then the issue popped up so I downloaded avg. I have about 9 billion sent and 32 billion recieved during the blackout time and the conection indicator in the bottom right corner only sometimes shows that it is having the connection issue but doesn't work compleatly even if it shows it is working at the time.

Now, I got a clear picture that it is not a hardware problem at your end.

I am 80% sure that the server is playing tantrums at the said time and so you need to screw your ISP on a serious note.

But the thing is that you need to prove the point to them and so must find out a way in doing so. Otherwise, there is no point in calling them up without a valid proof to show.

Otherwise, why don't you request your ISP for another IP address. May be this may solve your problem. If not then do as said above.
