Very slow internet speeds with new Crucial M4

post #1 of 10
Thread Starter 
So I have had multiple Crucial M4's in the past in this laptop and various hard drives and I have never run into this problem: My internet speed is very slow for some reason, particularly when downloading files. On sites that I previously got 2-3 MB/s download speeds I only get 200-300 kb/s download speeds with the latest wireless drivers (I have tried older ones too). Also, in Skype calls the calls are very laggy and they crackle a lot. Skype says the speed of my PC is slow. The 128GB M4 has the 0309 firmware.

I ran Crystal Disk Mark at 50MB and go the following results (Read/Write):

Seq: 481/194
512K: 343/191
4K: 21/30
4K QD32: 154/94

Also, latest chipset and Intel RST drivers are installed.

What is going on here?

I don't see how this could possibly be your SSD. SSD has no control over these things, and your SSD benched fine.

I blame your ISP, and/or network/chipset drivers.

I have tried multiple chipset and wireless drivers, so I don't think its that. I get very low speeds no matter what browser I use.

Speeds are fine on my other laptop and my phone though.

Is your duplex set correctly?

The SSD is no the problem. It is either your ISP or wireless settings.

How can I check that?

Make sure the connection is set to 1Gb Full Duplex.

Ultimate test...boot into a linux live disc and see if the internet is slow. This will completely eliminate windows as the culprit. If it's slow in Ubuntu then you know it's hardware, if it's not then you know it's windows.

Internet issues are not related to HDD or SSD as the benchmark shows good results.
Try download another browser like chrome or firefox and see if it has the same issues?
Try uninstall and reinstalling network drivers. Check if network socket has some dust in it?
Try TCPOptimizer.

SSD maintenance check-list:
Are you using the Intel SATA socket with SATA600?
Have you updated firmware?
Tried changing SATA cable?
Is ACHI mode in Bios enabled?
Have you updated Intel chipsets drivers and Intel RST software?
Is TRIM working in Windows?
Check if CPU bus speeds are normal and not overclocked?
Have you tried disabling C-States, Speedstep and Turbo boost?
After firmware update, did you try clearing motherboard cmos or try load optimised defaults then reconfigure?

(When C-States are disabled in BIOS; Sleep mode may not work)

Managed to fix the issue. I don't know what it was, but I reinstalled Windows but it works perfectly now.

Thanks for feedback and good to know that it's working.

(I really wanted to know the cause of the problem for future reference but I guess a reinstall also does the trick)
