Any network connection experts here? I need some serious help, little to no upload speed on a 10Mbps line...
Alright, this is part two of a question
I had asked a couple of weeks ago.
So I purchased the Intel PRO/1000 GT PCI card for my Windows 7 tower as suggested, no luck; with or without using my 3-week-new router (TP-Link TL-WR1043ND), it is the same slow upload speed at around 12.0kb/s and cuts out frequently. Tested as well with Avast and firewall off on a clean startup. Just to make sure it wasn't Windows, I installed a fresh copy of Ubuntu 9.10 onto a secondary drive and the same slow upload speed occurs, with or without the router.
Trying my Vista 32 bit laptop again (running a Generic Marvell Yukon 88E8071 based Ethernet Controller) testing the connection without going through the router and now apparently on this machine the download speed is slow, but the upload speed is fast (I originally thought the connection was okay in the original post; didn't test thoroughly). I installed a clean Windows XP SP3 32-Bit onto a secondary drive just to confirm this. So I tried again on both OS with the router, and now it becomes the same as my tower computer, fast download, slow upload. Problem with the router as well? Reset the router to its default factory settings, slow upload, with or without the router's firewall.
Now I try different cables, an old CAT 5, a CAT 5e, and even a CAT 6, still no fast upload speeds on both tower and laptop with each different operating system. I looked at the original cable provided by the building — it is a Signalmax brand CAT 5e cable and it looks (1) like
at the plug end with two colored-pair of wires (what is this configuration called?) unlike my other cables which all had eight wires packed inside. It took some investigating, but apparently if I use my own cables, the phone stops working (interference?) as the Ethernet and phone jacks are right beside each other in one panel, so I have no choice but to use the building's cable if I want calls to come through.
I now call over a technician from my ISP and my problem baffled him as well. But he had an HP netbook with a Broadcom NetLink Gigabit Ethernet controller and tested that the line was fine. Fast download and fast upload on speedtest sites and FTP, on both Windows XP and Windows 7 (both 32-bit). Nothing was fixed on my end since he can confirm the line was fine and he left.
Just hours ago, I tried advanced stuff for the 3 different network adapters like toggling Flow Control, Receive Side Scaling, trying all the different Speed & Duplex settings, still no fast upload speeds [do note that other than "Auto Negotiation" or "1000 Mbps Full Duplex" I get an orange light on the NIC (all 3), otherwise it gives a green light].
So now what are my options?
I do not want to believe that both my machines, 3 NICs, and my router all have problems. Is there anything else I can try? Could it be the motherboard? The BIOS? Should I buy a Broadcom NetLink NIC to see if it'll make a difference? What about my router? How does that explain the fast upload but slow download speed on the Vista laptop without using the router?
With my Windows 7 tower, on most speedtest sites, the upload part doesn't even go. If it helps any of the experts who are reading this, here's a couple of Network Diagnostic Tool results: http://pastebin.ws/d0ik82
In Gmail, I can't even attached a 120kb PDF file as the upload speed is too slow and times out. FTP doesn't even go. It is suppose to be a 10Mbps line but the upload speed is nowhere near (at least on my machines).
