I'm convinced that there are some network restrictions somewhere. I can't test samspeed since using my Netgear router as it isn't compatible. Samknows said my speed coming into my router was 1100 when not in modem mode but the speed going out never went above 100 so I didn't really trust what it was saying. No other traffic on my network when carrying out these tests.
PC more than capable of high bandwidth speeds. I'm currently running in modem mode with a Netgear Nighthawk but have tried both ways and it doesn't make a difference. I'm wired directly into my PC with a Cat6 cable. I get really poor download speeds compared to my connection coming in. This has been going on since I've had Virgin. I thought it must just be the steam download servers running slowly but me and my friend downloaded the same game at the same time and he was getting 110MB peak (Talk talk UFO FTTP) & I was getting 25/30 Peak. The best speeds I get are from the Sweden Malmo server. I've tried changing servers - Manchester server is closest to me but very poor speed wise. I get around 25MB peak download speeds from steam. This means I should be downloading from steam etc at a rate of at least 60-70MB/s. (Via - no other speedtest website gets anywhere near close to what my speed should be) My average download speeds are around 700Mbps (Should get nearer 1Gig as the package name suggests but thats for another time). Theoretical treatment of the LBV phase in stellar evolution, with consequencesįor their further evolution as single stars or in binary systems.I'm on GIG1. Our scenarioĪnd model provide testable predictions, and open the door for a consistent Outflow, and a mass-loss rate that increases with decreasing temperature,Ĭrossing a critical threshold value within this temperature range.
