Wifi Signal dropped by 60% - 70%
Hi
Windows 7 64 bit running (more or less) happily for a year or so.
Used via ethernet in one location and wifi in occasional other location (via an external antenna).
When I try wireless in the main (ethernet) location I get arond 10 or so SSIDs show up ranging from 5 bars down to 1
All has been fine until a few weeks ago when I started to get huge difficulties connecting to wifi in the occasional location. Often (say 60%) I could get a connection but no connection to the internet. Less often (say 20%) I'd get a connection to the internet that lasted maybe 5 minutes before disconnecting. Rarely (< 5%) I got a connection that held together for 30 minutes or more.
So I tried in the ethernet location (switched of my router wifi 'cos is swamped everything) and I get maybe 1 SSID showing up (whereas before there were at least 10). When I try to connect to that I get "Windows was unable to connect . . . " and the spinning blue wheel
I notice in device manager a couple of Virtual Wifi Miniports (#6 and #7) have appeared. No idea what they do.
The event log has a lot of Service Contol Manager 7036 events but no errors that seem relevant
IPCONFIG shows
I have no systemrestore points back before this all started (Ioriginally thought it was to do with the hotspot to which I was connecting)Code:Windows IP Configuration Host Name . . . . . . . . . . . . : HPDv6 Primary Dns Suffix . . . . . . . : Node Type . . . . . . . . . . . . : Hybrid IP Routing Enabled. . . . . . . . : No WINS Proxy Enabled. . . . . . . . : No Wireless LAN adapter Wireless Network Connection: Media State . . . . . . . . . . . : Media disconnected Connection-specific DNS Suffix . : Description . . . . . . . . . . . : Intel(R) Centrino(R) Wireless-N 2230 Physical Address. . . . . . . . . : 60-6C-66-7A-91-FD DHCP Enabled. . . . . . . . . . . : Yes Autoconfiguration Enabled . . . . : Yes Ethernet adapter Local Area Connection: Connection-specific DNS Suffix . : Description . . . . . . . . . . . : Realtek PCIe GBE Family Controller Physical Address. . . . . . . . . : A0-B3-CC-51-AD-68 DHCP Enabled. . . . . . . . . . . : Yes Autoconfiguration Enabled . . . . : Yes Link-local IPv6 Address . . . . . : fe80::6d81:a219:db0c:fd76%11(Preferred) IPv4 Address. . . . . . . . . . . : 192.168.1.60(Preferred) Subnet Mask . . . . . . . . . . . : 255.255.255.0 Lease Obtained. . . . . . . . . . : 03 September 2015 17:25:29 Lease Expires . . . . . . . . . . : 04 September 2015 17:25:29 Default Gateway . . . . . . . . . : fe80::8077:52ff:fe45:62c9%11 192.168.1.1 DHCP Server . . . . . . . . . . . : 192.168.1.1 DHCPv6 IAID . . . . . . . . . . . : 295744460 DHCPv6 Client DUID. . . . . . . . : 00-01-00-01-1B-90-05-E6-A0-B3-CC-51-AD-68 DNS Servers . . . . . . . . . . . : 192.168.1.1 0.0.0.0 NetBIOS over Tcpip. . . . . . . . : Enabled Ethernet adapter VirtualBox Host-Only Network: Connection-specific DNS Suffix . : Description . . . . . . . . . . . : VirtualBox Host-Only Ethernet Adapter Physical Address. . . . . . . . . : 08-00-27-00-70-70 DHCP Enabled. . . . . . . . . . . : No Autoconfiguration Enabled . . . . : Yes Link-local IPv6 Address . . . . . : fe80::81bf:8de:8863:97de%21(Preferred) IPv4 Address. . . . . . . . . . . : 192.168.56.1(Preferred) Subnet Mask . . . . . . . . . . . : 255.255.255.0 Default Gateway . . . . . . . . . : DHCPv6 IAID . . . . . . . . . . . : 755499047 DHCPv6 Client DUID. . . . . . . . : 00-01-00-01-1B-90-05-E6-A0-B3-CC-51-AD-68 DNS Servers . . . . . . . . . . . : fec0:0:0:ffff::1%1 fec0:0:0:ffff::2%1 fec0:0:0:ffff::3%1 NetBIOS over Tcpip. . . . . . . . : Enabled Tunnel adapter isatap.{38689B62-749E-4F13-B91D-4AAFB15BB4BF}: Media State . . . . . . . . . . . : Media disconnected Connection-specific DNS Suffix . : Description . . . . . . . . . . . : Microsoft ISATAP Adapter Physical Address. . . . . . . . . : 00-00-00-00-00-00-00-E0 DHCP Enabled. . . . . . . . . . . : No Autoconfiguration Enabled . . . . : Yes Tunnel adapter isatap.{FB543D10-8D1F-449D-B4E5-15949A81BD77}: Media State . . . . . . . . . . . : Media disconnected Connection-specific DNS Suffix . : Description . . . . . . . . . . . : Microsoft ISATAP Adapter #2 Physical Address. . . . . . . . . : 00-00-00-00-00-00-00-E0 DHCP Enabled. . . . . . . . . . . : No Autoconfiguration Enabled . . . . : Yes Tunnel adapter Local Area Connection* 12: Media State . . . . . . . . . . . : Media disconnected Connection-specific DNS Suffix . : Description . . . . . . . . . . . : Teredo Tunneling Pseudo-Interface Physical Address. . . . . . . . . : 00-00-00-00-00-00-00-E0 DHCP Enabled. . . . . . . . . . . : No Autoconfiguration Enabled . . . . : Yes Tunnel adapter isatap.{0545CF7C-F847-42BD-99D3-E092E5B33CFD}: Media State . . . . . . . . . . . : Media disconnected Connection-specific DNS Suffix . : Description . . . . . . . . . . . : Microsoft ISATAP Adapter #6 Physical Address. . . . . . . . . : 00-00-00-00-00-00-00-E0 DHCP Enabled. . . . . . . . . . . : No Autoconfiguration Enabled . . . . : Yes Tunnel adapter isatap.{09EBA21E-CDF7-4C29-954F-422F8E375A63}: Media State . . . . . . . . . . . : Media disconnected Connection-specific DNS Suffix . : Description . . . . . . . . . . . : Microsoft ISATAP Adapter #10 Physical Address. . . . . . . . . : 00-00-00-00-00-00-00-E0 DHCP Enabled. . . . . . . . . . . : No Autoconfiguration Enabled . . . . : Yes C:\Windows\system32>
Any ideas welcome but think Im headed for a repair install
PS I just tried an external antenna and the signal strength is way down on what it used to be. So it does seem something (software) in hte PC is screwing things up but I have no idea where to start looking
So I guess I start uninstallling things and work backwards in time
