Does the A record for swt.passsengerwifi.com differ for each unit? If not, you could 'manually cache' its IP in your hosts file, and get to the login page without needing a DNS query each time.
Every four or five block of coaches you have to login again. However the up address 198.162.100.1 doesn't change.
On the Portsmouth line the state of the wifi is now such that I no longer try it, particularly since the last log in variant. If SWT are paying for it, they should stop.
The WiFi was really good until they switched to using the new address. Now even the IP address doesn't work.
It use to be like this near the start of the rollong and then it eventually become good for a time. So clearly they could do something to make it good again. Not sure what's changed technically to cause the issues.
If like they did before, they resolve the issues, it will improve.

They are. Many new sites from EE as it will be providing coverage for the emergency services, while Vodafone and O2 are upgrading all their old 2G (and useless 3G) sites to 4G. Vodafone is also switching a lot of 2G to 3G, but with sufficient back haul so you'll actually get more than 0.01Mbps or similar!
By 2018, expect big improvements from all. By 2020, EE should be giving 4G to pretty much all land mass, so that will mean railways and motorways covered. Speeds won't necessarily be amazing, but I'd expect 10-15Mbps or more. Elsewhere, speeds will be offered of 600Mbps or more!
Well every so often I get a message from O2 to say they are making improvements for my 4G. After some of these messages, they announced am upgrade so I would get 4G. I asked on twitter about the fact how can I get 4G if I already had it. They never gave me a good enough answer.
As for the 4G it's patchy where I live to say the least.
In Surbiton, which I pass through at times, it's also patchy and at some parts it's non existant and that includes for voice calls! That's not even on the railway lines and I'm talking about outside rather than inside!
Of course there map says it's all fine. I did raise it in the past and some improvements occurred but not every where and it can be variable at times still, in the places where it does work.
