20meg speed trouble

Dazzle1969 · 23-10-2008, 10:09

I'm having trouble with speed with my 20meg and noticed:
Receive Power Level - 12.4 dBmV
Transmit Power Level - 50.0 dBmV

my modem is the WebSTAR EPC2100R2

Could the receive power level be too high as i've noticed everyone seems to have a far lower number and if so what do i do about it

Thanks

That is borderline low, and if you are having issues regarding speed then a call to Tech Support will probably be in order.

sorry to butt in guys, but i checked my power levels yesterday evening and got the following any onfo
my modem is a : euro-docsis 1.0/1.1/2.0 compliant
upstream transmit power level 51.5 dBmv
downstream recieved power level is minus (-1.5dBmv)

I,m on VM,s 20 meg service but get around half that when doing a quick speed test

What speeds are you actually getting, and are you sure it's not traffic managed speeds or just slow speeds from wherever is serving whatever you are downloading?

pabscars · 24-10-2008, 10:11

in all fairness, i spoke to a gent in tech support and he said to ring back later from home, and he would have another look at it, he checked the modem power settings while i was on the phone and said they were fine, re speeds ive checked at all times during the day, weekends, mornings and evenings and never get a decent download speed, but normally get 700+ upload.
when i went home yesterday i fired up the pc, bearing in mind its connected wirelessly, and got a fluctuating 3 meg max, and an upload of about 500ish. this was the first time i had been online that day, so traffic management shouldnt have been an issue should it. when i first had VM BB installed i did do a speed test and got approx 12 meg, but ive never been able to get that since, it can be anywhere from 2.5meg to 8ish. how can you tell if you are being traffic managed?

books · 24-10-2008, 10:56

I don't know if there is anything you can do to tell if you are being managed. I just know if I am because it's really obvious on my connection. Stuff either blasts down at almost the max speed of my connection, or it crawls down at a ridiculously reduced speed when I'm being traffic managed.

There are some things you can download that come from high speed servers so you know if it's crawling down at a slow speed, then you are being managed. Or you can do a speedtest.

It's possible you have a fault though, but something you could try would be doing a download or a speed test outside of traffic managed hours and when you haven't downloaded anything. So for example the traffic management starts at 10am, so if you can get up early and do a speed test and download some stuff before work at like 8am or something, then you know that you should be getting your full speed then. If you aren't, then either you have a fault, or you are just in a busy area with lots of contention. Something you can also try is plugging your PC straight into the cable modem, rather than going via your router. That just helps eliminate the router as a problem.

From what you said, the 2.5mbit speed sounds like what I get when I am being traffic managed. But the 8ish is a bit unusual sounding, because it's more than you can get while being managed, so if that was your normal then that would be really poor. And in that case I would be calling them up and asking for tech support and asking them to help to make it faster. I think on a 20mbit connection, anything around 16+ is ok in my opinion. Anything around 10 or less and it's a waste of time being on 20 in the first place.

will take on board your advice, and will phone them up later today and post replies
thanks

right, i think i,m getting somewhere now, nipped home at lunch, flicked on the laptop, waited for a gazillion years for it to wake up, plugged it into the modem via ethernet and nothing.....

so booted up the wireless router, plugged in via ethernet again, did a speed test and the result was 17200 down and 711 up... WOW what a result (BACK OF THE NET)

removed the ethernet and tried wirelessly and the speed more than halved to 7.2 down but still 710 upload, so somehow it would appear i,m loosing 10 meg by being wireless, distance cant be the issue because i was less than 2 foot away from the router, so now i dont have a clue what to try next, obviously Virgin are upholding their end of the bargain, so Bo yakasha to VM,
next question is what can be done to improve wireless connectivity, ive tried all RF channels and they all appear to give the same results, ?????
i think i know what may be recommended (new router) right?

Are you able to adjust the MTU settings in the router config?
I don't know if your TCP settings for the WiFi would need adjusting.

Try TCP/IP Optimizer?

yes can adjust MTU settings in router, currently at 1500. will try tcp/ip optimizer and see how things pan out.

Hi Gary L, thanks for your advice, it worked a treat, ran the TCP/IP Optimiser, and voila speed increased significantly, so i,ll buy you a pint at christmas lol.
i do have another question that may or may not be connected to this thread, apologies if not but here we go.
Playing on Call of Duty4 on xbox 360, i now have a good enough connection to host occasionally on team deathmatch's, however when i,m hosting the connection the opposing team get is fantastic and the one i and the rest of my team is laggy to say the least. after a short space of time it comes up with host ended game, when i havent.
i then get dissed by all in the lobby saying my connection sucks.
come on guys get your thinking caps on, if any of you can come up with a remedy i will invite you too have carnal relations with her indoors (40DD) as a thank you
ps thought that might get your brains into gear,

My mate couldn't connect to me last night, setup his port forwarding and we played fine!
Or put in the IP into DMZ.

pabscars · 27-10-2008, 14:01

i already have my ports forwarded and triggered for xbox live, and have also tried DMZ, never seemed to make much difference though, will try again tonight to make sure, but last night some friends were breaking up when having discussions in a lobby, one thing i did last week was, in my netgear router settings there was a box to tick to (open NAT) which i ticked, expecting this to improve things further, even though my xbox's NAT status is OPEN already, ive noticed for quite a few weeks now that, even i can get booted out of games, or wont connect to friends games etc. It didnt seem to be a problem before on my ADSL line
