The past 2 days or so I started strange connectivity problems with certain IPs including a server I host in US. My BT configurations is the default, with Wireless disabled. I see typical speeds of almost 400KB/sec usually but with some IPs transfers drop to just few KBs/sec although the servers have no problems. Tested from different locations and I do not see the problem. Also I tried with several proxies and there is no issue. The problem appears to be when a direct connection takes place. The host asked my to contact my ISP for connectivity/backbone issues regarding this and so here I am. Other things I tried in the past 2 days. - Reset the router tried with different IPs same problem. - Checked trace route everything looks normal no latencies to target IPs. - Tried different PC systems different browsers, ftp tools etc, no difference Anyone knows what is going on?
This problem is now solved. It was the router cache that was causing the limited transfer rates for some sites. Following recommendations from bt support I had to reset the router to factory defaults. I was able to see normal speeds thereafter. It happened with the stock bt router 2701HGV-C as they said there should be a fix with the upcoming firmware updates. Hope it will help others facing the same issue.
