Tmobile home internet and Zscaler
Recently my company switched to ZScaler for VPN/Firewall services. They have had some internal issues however it appears Zscaler and T-Mobile internet aren't agreeing. When on my home network my download speeds get reduced to .1-.3 Mbps, while other devices such as cell phones and personal computers see 20-40 Mbps. I was curious if anyone else has seen this issue, otherwise I love the T mobile service in my area (rurual), however I need to have working internet to complete my job when at the house.

Hola Marc
There appears to be an issue with the mtu size in the zcalar policy.. I believe the mtu size was reduced for policies associated with users that have wireless internet service.
Since that change it has been working well for users in USA and Europe
I'm sorry, I'm not very technical. I can see there's a problem w/ MTU size (but I don't know what that means). When you say "I believe the mtu size was reduced..." what does that mean, who reduced it? T-Mo? Because as of Monday this week, my work Win PC was literally un-usable on my TMHI connection (wired or wifi). As is the case with most corporate PC users, it's locked down w/ only admin access to changing things like MTU, and as a typical PC user, I don't have the skills to do it, even if I had admin access. I have requested our IT support to help, not heard back. *If there's anything I can do to reach out to T-Mo tech support to get MY connection to work w/ this PC w/ z scaler, please let me know?*
The zcalar policy mtu size would need to be adjusted by those who managed the deployment. It is not something that is t-mobile would adjust or you on your pc. I was not involved with the policy deployment just worked with our security group as they figured out the best value. The default may be 1500 but since you are using wireless internet the value may need to be reduced by 28 bytes values until you are able to work.

Got it, thanks for clarifying! I thought you were saying or implying T-Mo could do something on the tower end, obv they cant do anything to a local PC.
