slow speeds, it appears it might be my router

[Byte 2.0]

Ok, for about a week I have been having slow upload speeds and normally I don't say much about it. Normally It is with in reason. But lately it started bothering me.

I have a Motorola surfboard connected to a Netgear 814MR router, 3 PC's connected directly to the router.

I have had several firmware battles with Netgear, finally got it stable and working good.

Now for the past week it has been running slow and I figured it was comcast. Tonight, getting ready to call them I run some speed test and was getting like 1500 down and 40 up.

basically I have good down stream and my upstream is like dial up. I unhooked by router and my speeds changed to 1500 down by 200 up..

upgraded by firmware a again, no difference. reset by router it seems to be ok for a while but my uploads are slow enough to cause me lag, once me requests get out to the net it is fast.

I am continuing the tests, the speed difference might have been turning stuff off and back on, it may get down bad again with just the modem.

but what is the chance it is the router?

opps, I may have found the problem. about a week ago, i was just screwing around and while playing with security in my router, i thought it would be a good idea to forward port 135 to an IP on my network that is not being used by anything. since I have one PC running in full DMZ mode, i wanted to make sure it didn't hear from port 135. seems to be performing better now. I will watch it and see, too soon to tell.

nope, that was not it.
still dropping speed and I noticed sync lost on my modem.
I called tech support the guy said he was getting high latancy in the pings to my modem, not my PC. He said it appeared to be an issue with the NODE that I am connected too. He then said it was strange but appeared that i was the only customer connected to this mode(I didn't believe that)

He said he could not just have a tech check the node, it would require an appointment to my home, which i know the local tech just wants to blame modems, which i have 2 difference ones that i can switch between.

I am going to try and talk to the local office tomorrow.

Does it run at full speed connected directly to the modem? Of course, if you're getting high latency on the cable company's side, I'd check your coax from the cable company's entry point, just to make sure it's not there.

my downstream is just fine, it is my upstream. since my upstream is low, it gives the appearence of slower speeds because my outgoing requests are slow, even connected directly to the modem.

[gunrunnerjohn]

Upstream is the more critical connection component, since your cable modem is doing the transmission, and there are lots of other cable modems in nearby bands. I've had a bad cable to the modem cause my issues because my upstream signal wasn't strong enough, but I was getting loads of signal from the ISP's network.

Once again, I'd check the integrety of the cable from the entrance to the modem. I'd also make sure you have a quality 2:1 splitter at the entrance and a straight run as short as possible to the cable modem, and use quality cable.

If I'm faced with coax issues, I dig out my Tektronix 1503C TDR and test the line, but not everyone has one of those!

Any splitters in the cable between the outside feed and your modem must be 1 GHz bandpass or higher, and be passive - no amplifers permitted.

ok, back to blaming th erouter, I have had the modem direct for a few hours today and it has maintained good upload.

I just got back from taking my router to work and connecting it to a DSL modem and upload sucked, 46 killbites per second up.

only think that was the same was the router and the ethernet cable found router to modem, going to try a different cable, but I am supecting the router now.


about the wiring, there is ONE spilter comcast installed outside, one lead is about 4 feet from the modem, other goes to a TV. That is it. All the cable was put in back in march. they connections are tight, nice and new, the cable has nice flex to it, not old and dried out. But I believe it is the router now.

since I have maintained an upload of 28/29 KB/sec for the past 3 hours, with out the router.

Going to call Netgear and try to get a replacement. this router has been junkie since day one.

I may have found the problem. during all my tests with the router I used the same ethernet cable. I finally connected it with a diifferent cable and now i am currently maintaining my upload speeds. the modem to router ethernet cable must have gone bad, got punched or something odd, looking at it of course I can not see a problem but it was in all the tests with the slow upload speed, once it was removed i am holding at my upload at my cap.
