Windows 7 Wireless Intel Ultimate-N issues

[Seren]

Hey,

I recently bought a new laptop from BTO (15M49) and I've been having trouble with my wireless connection. The first thing is that in task manager the link speed sometimes varies quite a bit (118mbps -300mbps or so). This might not actually be a problem but still wanted to mention it..
The main issue is that I rarely achieve my maximum internet speed (testing with ziggo.speedtest.nl) of about 50-52 mbps. it hardly ever goes above 46. Along with that, while I am downloading anything at that speed (46 or so mbps) it is nearly impossible to do anything else online. In that case I cannot even load my router's inlog screen.
This issue does not occur at all when I'm connected to the router by wire. My old laptop did not have this problem either.
Also, in adapter settings I turned IPv6 off as that seemed to make the link speed vary even more..

System:
BTO 15M49 (MSI GT60 0NC)
Intel core I7 3610QM
12GB (3x4GB) Kingston HyperX DDR3-1600MHz
NVIDIA GTX670M 1.5Gb GDDR5
Killer e2200 Gigabit Ethernet
Intel Centrino Ultimate-N 6300: driver 15.1.0.18 from BTO
Seagate 500GB +4GB SSD hybrid
Seagate 750GB HDD

I allready tried updating the driver to the latest on the intel site which had no effect, also all power saving options for the WLAN are turned off (in adapter settings and power options)

In adapter settings:
2.4GHz channel width: auto
802.11n mode: enabled
Bluetooth AMP: disabled
Fat channel intolerant: disabled
Mixed Mode protection: CTS-to-self enabled
preffered band: no preference
Roaming aggresiveness: medium
transmit power: 5.Highest
Wireless mode: a/b/g

My router is a draytek vigor 2130n with the latest firmware in n-mode only and WPA2 security on channel 7 and 3 which are not used by any other network in the neighbourhood (checked with Xirrus)
I allready tried turning WMM off in the router, which had no noticeable effect.

Laptop is obviously checked for virusses and spyware with Microsoft Security Essentials, Malwarebytes and Spybot


I hope someone can help me figuring this out,
Thanks in advance
Sander

Hi Sander, It seems like you've done quite a bit of troubleshooting already, but let's dive into some additional steps to help resolve your wireless connection issues on your BTO 15M49 laptop. Here are some recommendations to further troubleshoot and potentially improve your wireless connection: 1. Signal Interference: - Check for any potential sources of interference near your laptop or router such as other electronic devices, cordless phones, microwave ovens, etc. These devices can weaken your Wi-Fi signal. 2. Driver Update: - While you mentioned updating the driver to the latest version from the Intel site, it's worth checking if there are any updated drivers specifically from BTO for your Intel Centrino Ultimate-N 6300 wireless adapter. 3. Network Adapter Power Management: - Double-check the power management settings of your network adapter: - Right-click on the Start menu, select Device Manager. - Locate your wireless adapter under Network Adapters, right-click on it, select Properties. - Go to the Power Management tab and uncheck "Allow the computer to turn off this device to save power." 4. Wireless Channel Adjustment: - Try manually setting your router to a specific channel (like 11) to avoid interference from neighboring networks. Test to see if a specific channel provides better performance. 5. QoS Settings: - Check if your router has Quality of Service (QoS) settings that prioritize traffic for specific applications or devices. Adjusting these settings might help alleviate the bandwidth issues you're experiencing. 6. Network Troubleshooter: - Run the built-in Windows Network Troubleshooter to detect and resolve common network-related problems. 7. DNS Settings: - Try changing the DNS settings on your laptop to use Google's public DNS (8.8.8.8 and 8.8.4.4) or Cloudflare's (1.1.1.1 and 1.0.0.1). This can sometimes improve connection speeds. 8. Firmware Update: - Ensure that your router's firmware is up to date. Sometimes firmware updates can address performance issues. 9. Different Speed Test Services: - Try using different speed test services (like Ookla Speed Test) to verify if the speed issues are consistent across multiple platforms. 10. Contact BTO Support: - If the issue persists, consider reaching out to BTO support for further assistance, especially if the problem seems to be hardware-related. Keep monitoring your connection after implementing these steps to see if there are any improvements in speed and stability. Let me know if you need further assistance or if you notice any changes after trying these suggestions.
