Alright, in short (I tried...), here is a list of what's happened today:
1) I disconnected the router, took it upstairs, reset it and accessed the router page. The page was password protected, and I found out the routers provided by my ISP have custom firmware on it to be instantly compatible with their modems. This software also builds in another default password and a firmware-upgrade block.
2) I set the router address to 10.0.0.1 and followed your instructions. I experimented a bit with different channels, to see if interference had anything to do with the issue, and to a certain extent it did. One channel would have 30-300 ping, while the other had 30-600 ping. After a while of testing, all channels blurred into the same ping-range of 50-800 with spikes to thousands or 'request timed out'.
3) I looked up this specific router from this specific ISP, and noticed many many people having trouble with it. Basically it's causing nothing disruptions in connection, lot's of people experience disconnects, slow internet, etc. They all said to return the router and get another, decent, router.
4) Both tracert and pathping trace to my router, and time out after that. They never seem to reach my ISP's address. Despite this, internet connectivity seems to work (albeit very slow, with disconnects here and there, like I'm used to by now) 'normally'.
My questions:
- Is it possible their custom (but very outdated, theirs is at 1.0.3 or something, and the latest is 2.0.26) firmware is messing things up? If so, is there any way to update the firmware despite the update-block? People wrote that even manually updating is restricted.
- Could it be that local channel interference is messing up the signal? I did see a difference between certain channels in the moments just after reboot.
- Why can't tracert and pathping reach my ISP? Could it still be that they're messing up on their end? After all we saw the ping spiking up from the pathping hop between me and the ISP.
- After reading and assessing all this, wouldn't it just be easier to urge the house admin to contact the ISP and if need be return the router for another? Or even change ISP if things persist?
Edit: I looked further into the frequency thing, and downloaded "inSSIDer" to scan my area for used frequencies and channels. I saw a few heavily used ones, but this graph stood out for me. My router (blue one) has a frantic graph, going up and down in frequency like crazy. That can't be good, right? Is that the routers fault? Could it be what's causing my problem?
