Have tried unnstalling btooth (no adaptor is physically prsent), but the tray icon for IVT Bluetooth just reappears on re-bbot - done this twice. Maybe I should find and run my old msicuu2 file? Have unistalled (again) PCSuite. Have also fiddled with network settings a bit aimlessly, but it's all still the same - other computers are all fine whilst this one only works in safe mode.
When I came on just now I have just spotted your question about routers and subnet masks. I do not fully understand how to "work" through forum replies in a logical manner. More to the point I do not understand a lot about routers and subnet masks. I did try to explain a fair bit abou having the multiple routers in a long post here a day or so ago.
To recap and elaborate: because the internet was critical to us I double provisoned its supply to our house and added an ADSL service to the existing canle service. Gave the wi-fi networks SSID's of 120120 and 120120o2 respectively. Had some wired PC's on one, other wired PC's on the other. The laptops had the password for both and would go on one Wi-Fi or the other depending on which was the stronger signal. Some parts of the old house with thick walls and the garden building would be struggling on the original cable service. Sometimes the automatic choice did not happen well and people would manually switch for good results. So that was about 4 years ago and all was well. I did notice but certainly did not mind rthat the default gateways were different - 192.168.1.254 and 10.0.0.1 - it kept things separate and working well. Of course some PC's or laptops could not see some others or some hard drives or media locations, as they were on the other network. So, as our household cable bills started to soar at the whim of the cable company they stopped being willing to keep themselves competitive and less than a year ago we left the service. But, still needed good reliable broadband over the house upstairs and downstairs and to the garden building. For a while I ran a physical newtwork cable up the stairs fronm the ADSL router to the upstairs router which had been fed by the cable modem. In other words, one network port from the downstairs router (192.168.1.254 O2 router generating also its wi-fi of 120120o2) was now plugged in to the internet supply port on the upstairs router (which is at 10.0.0.1 and also geerates 120120 wi-fi and had been connected to the cable modem until then). This was nearly a year ago and I do remember that there were / are other PC's plugged into the upstairs router and hd's for merdia and for backup, so there were / are also a couple of network switches involved and it became quite tricky for a few days working out the best way to concertina everything so that it all had internet and network access. A while later as the network cable running up the stairs became a domestic issue, I invested in about 4 mains networking adaptors. You supply one with the internet and get each of the others to pair up with it, so they generate an internet and network feed. One of these is for the audio / tv, one is by me in the evening, another is feeding the bedroom TV smart box with catch up but as you have guessed of course, one of these now feeds the former cable router. I did consider but had no info and found nothing relevant as to whether to try to put both routers on the same default gateway address and / or indeed whether to put them both on the same SSID and if so, whether with the same wi-fi password, so I left everything "separate" just as it had been. I did need to put a fresh switch into the upstairs network cabling and re-arrange the way the mains network feed arrived at the main upstairs PC, in order for both the network devices and the internet to feed that PC and the other one or two en route, but this was by an empirical following through of the leads and some head scratching and I do know that it all works brilliantly on everything, up and down, except this one PC here, which is indeed right by and plugged into the o2 source router.
I expect you will have a field day over the unorthodoxy of all this, for the more I learn, the more I see there are other things to be considered. However, it is also true that this PC was replaced in day long use nearly a year ago after a despeate 2 weeks of trouble shooting (including my discovery of the wonderful Windows 7 Forms) by a laptop, simply because of lack of internet. So that laptop usually sits infront of the PC's LCD and the PC is typically off, or sitting in Safe Mode where it cannot do much, but it has webmail and internet at least. And I plug the laptop into the router, just like the problem PC. Now, the laptop does have Wi-Fi recognising both wireless newroks, but I am now going to fetch that laptop which I've sat out of the way for now, switch off its wi-fi and plug it into the router and check for broadband internet, which I'd be amazed if it isn't coming through. So hang on a mo, please....
Yes, indeedee, both wi-fi netwrks and the wired network if wi-fi is switched off, all work. So the problem is completely specific to this PC. I did spot / remember on the laptop the iPhone network - one can tether a computer to the iPhone and receive "free" broadband, so when I sign off this post, I will try that in normal mode, it does not seem to be seen in safe mode, probably unsurprisingly.
So, I hope this all helps and I look forward to everything - possibly including a torrent of "you can't do that" - no, I hope not, really, I do hope we can crack this. I may btw have to be away for a few days workwise, will confirm soon if so.
Thx. RickyQ
