There is a DSL connection and a DSL router (Speedport W 701V). After some days or weeks (I didn't record the events) the router makes some problems.
- Internet connection is ... broken but not completely disconnected. E.g. requesting a website the page either gets "displayed" very slowly or does not beeing "displayed" at all. A retry sometimes results in more success. So the connection isn't completely gone, but very slow and nearly unusable.
- It is almost the same when I request the router's config web interface.
- A ping to google and to the router itself, both result in massive package loss.
That's why I think, it is more a router problem. And in fact: If I restart the router, everything works fine again, for weeks until the same problems occur again. This is going for years now.
I personally don't know why this is happening. Looks like a software problem (on some level) of the router, because it is not permanent and a reboot solves the problem temporarily.
But to do something I need more information. Unfortunately the routers web interface is limited and does not show anything suspicious. That's why I ask:
How can I get more information about what's going on there?
Here are some approaches that came to my mind:
- I may capture some traffic with ethercap / wireshark and analyse it, but that seems to be complex and time-consuming.
- What's with ICMP? I never used much more than a ping. Aren't there tools with which I can inspect the routers internals?
- Seems like the router does not support SNMP. At least I got no response on
snmpwalk -v1 -c public 192.168.1.1.
Any hint's on cause / root of the problems are welcome, too.
P.S. The router's firmware is up-to-date.
