Try setting your computer IP to a fixed value (not auto) such as 192.168.1.12 and make sure that BC has a fixed port value corresponding to one set on the router for that poarticular intranet IP.
Don't use just one DNS - use both 8.8.8.8 and 8.8.4.4. Sometimes you may need to use 192.168.1 as primary DNS with 8.8.8.8 as secondary, but 8.8.4.4 is also needed. Try it both ways
That set of red lines tells me absolutely nothing. If you want a ping value, open a command prompt and type 'ping 192.168.1.1' (without quotes) and also try a ping to your isp (do NOT post that IP here or anywhere else)

hi , red lines is time when packet loss happen, it happen every 30 mins, i can not give you a ping result, i capture it with pingplotter ( ping monitor program )
Just set IP to fixd value but it still have packet loss , when i turn off BC, packet loss is disappear after some minutes , i thing BC trigger something
Here is my video for easily imagine š
Type 'ping 192.168.1.1' and just note the response (it will run four times)
Do the same for 8.8.8.8 and 8.8.4.4
Packet loss is when you receive corrupt data - it's nothing to do with bitcomet but more to a defective packet (data corrupted or paclen was incorrect)
It should be obvious really that you will only have packet loss when you receive packets - if you aren't sending or receiving packets then you simply won't have any packets to lose

i use ping every time I use my PC , so packet is send & receive frequently , but can you suggest me to check something with BC because every time I open BC, packet loss happen immediately
pls see my video

If you are unwilling to tell me the results of a ping in COMMAND PROMPT, there's nothing further I can do

sorry youtube delete my video , here is every i capture on my screen , include ping result ,pls take a look at this
Your computer is only connecting intermittently to the router.
It's possible that you are not setting the gateway correctly
Try this in network settings
IP address 192.168.1.21
Netmask 255.255.255.0
Default Gateway 192.168.1.1
Use the following DNS server addresses
192.168.1.1
8.8.8.8
in advanced add 8.8.4.4
Open your router settimgs in a browser (http://192.168.1.1) and set it for post number (any five figure number you like) and assign that to 192.168.1.21 for both TCP and UDP
In bitcomet set your port number to match the one in the router

ok thanks, i ll give i a try
Amarsi - that sounds as if you are losing the connection to the trackers. Itās obviously not a common issue (or this thread would be full of āme tooā posts).
Now, whether the problem is between the computer and router or the router and the trackers, I honestly can't say. It could be anything, including out of date network drivers, router firmware or even your ISP interfering (mine used to do that at one time and slowed down any transfers if they felt I was using too much bandwidth). It could even be a windows issue.
As I said, it's unlikely to be BC itself or we would have a huge number of posts on the subject - so far it's only two.
Tracker errors are not only possible but to happen. Look ay thje bottom of the āstatisticsā window and youāll see the number of āDNS failuresā
Itās definitely problem with DHT, since i updated from 1.64 to 1.74. ( Never had this problem before, on the older version )
Whenever u start up bitcomet it get's bombarded with thousands of connections and this gets fixed once u disable DHT in options.
Hope you can fix this issue in 1.75
The default value for DHT is, if I recall, 1,000 magnet files. If youāre downloading more than that, thereās something wrong with your setup. Try deleting all the entries in Torrent Exchange and see if that improves things

I have to wait around 5 minutes until all sessions are gone, have no idea what is causing it./monthly_2021_02/BitComet_2021-02-26_02-15-27.png.c42bfd6af78beb33402f57be9973eb36.png" rel=""> This
Everytime i start bitcomet with DHT enabled, it has lot of sessions.
And yes, I removed all entries in torrent exchange and also history. That didn't fix it. ( The only thing that fixes it is to disable DHT and when U launch bitcomet it has 0 sessions )

Default settings is set to 1000 magnet files, idk what really is causing this.
When i launch bitcomet it takes like 3-5 seconds to boot up, it was never like that on the older version.

Using this version, i updated it directly from the client.
