Merged WIfi connection issues

[Lothian]

I am having problems connecting to the internet with my pc and getting any speed.

My old PC packed in and wouldn't connect to the internet but woudl connect to the router. I bought a new PC and after appearing to run Ok for the first week the problerm has returned. I was getting the no internet problem although it was conencting to the router. I tried


netsh winsock reset
netsh int ip reset
ipconfig /release
ipconfig /renew
ipconfig /flushdns

and reainstalling the diver, with no luck. In the end I just reset the PC but the problem is back. I am only connecting with wifi.
the router and computer have bothe been restarted.

Running a speed checker I got the folowing. I have fibre into the house and think I was getting downloawd speeds when it was installed up near 100 Mb/s

Any clues?

Have you tested with connecting via LAN cable to the router directly to see how fast the internet is coming in ?

Curious that the 3 devices produced such different speeds.

Sticking with the more primitive switching-it-off-and-on-again school of repair, do you have a device which does the media conversion from fibre optic to copper cable, and have you restarted that? Since we got fibre to the home, we've had both the usual hub/router and also a small wall box where the incoming fibre terminates and which links to the hub with a Cat 5 cable. We've had to power-reset that at least once.

I suspect it's too low level a device to cause a difference between different computers, but it might be worth a try.

Just to confirm: It is only the pc connecting wirelessly direct to the router that the problem occurs?

 

[Orphia Nay]

Have you checked for local works/outages with your IP?

 

[Wudang]

Contention? One place we rented an office in I used a Wifi analyser app to test for problems and found the nearby school had a bunch of BYOD access points on the same channel.
At home I had a problem for a while as a critical cable (FTTC to the router) was poor quality.
When my street was upgraded to FTTP there were a number of people reported their speed dropped as new premises were added. Contacting the ISP (zzoomm) their engineers fixed it. I think it was some suboptimal configuration that wasn't obvious until the load increased.
Have you tried traceroute ?
Random thoughts.

Yes

Does your hub use both 2.4GHz and 5GHz wifi, and do you know which one each computer is using?

 

[Lothian]

Have you checked for local works/outages with your IP?

Am on to that tomorrow.

Have you tested with connecting via LAN cable to the router directly to see how fast the internet is coming in ?

No the router is in a different room. I can try plugging the work laptop top in to the router

 

[Lothian]

Does your hub use both 2.4GHz and 5GHz wifi, and do you know which one each computer is using?

Yes it has both and no. The router only appears once in the list

Yes I have turned that on and off and unplugged it

Should take approximately 1 minute checking online.

I'm wondering if it is an IP clash.

Does the pc use DHCP, or is it a fixed IP?

What are the DHCP server settings on the router?

Can you see what other devices are connected to it, and their IPs?

When odd stuff happened with our previous router we renamed one of the wifi frequencies (adding a "5" on the end of the 5GHz SSID and did the same to its password). That made the two frequencies appear as different hubs, which helped us diagnose why some devices kept losing connection while others had no issue.

Ok in the room with the router I get 115Mb/s on WiFi on the laptop. Bank in the "computer room" I am now getting 70 on the laptop. On the PC I am only getting 10mb/s

There are 9 devices at 2.4 GHz and 6 at 5GHz. Not sure if the desktop listed is the one. Those are the 5 GHz connections.

 

[Norman Alexander]

Thanks. If that is the desktop, it confirms it is using DHCP, which is normal in a household setup. So it is unlikely it is an IP clash.

Can I ask what the wireless hardware is in your desktop? Is it built in? An installed wireless card (with an aerial)? External dongle plugged into a USB port?

I agree with Zaganza by testing using a cable connection if possible. If the speed dramatically improves then you have a PC wireless issue. If it does not, it is some obscure network setting glitch between PC and router (harder to diagnose).

One thing I found does tend to help with LAN testing. Assuming you have anti-virus installed, disable all levels of the Windows firewall. Windows will get all annoyed, but do it anyway. I have had PCs with earlier versions of Windows suddenly perk up and run well just by doing this. It means you will need to tune the firewall settings later.

Intel(R) Dual band wireless-AC 3160

Built in.
